Chapter I

Tutorial

-x-

Naruto Uzumaki, son of Kushina Uzumaki and Minato Uzumaki was what could be regarded as… a closet pervert.

Similar to his once best friend Issei Hyoudou he was exposed to things such as sex and the like at a young age by a wandering perverted old man that used to preach about the magnificence of breasts. The old man apparently wrote porn books in his spare time so his accountings and descriptions were quite detailed.

Issei took to it like a fish out of water as he was corrupted to the point where he developed a fixated obsession with breasts himself.

Naruto on the other hand while also having developed an early interest in the opposite gender and sex in general was a bit more reasonable with his desires and held them close rather than shouting them out to the heavens like Issei.

This however eventually led to a gap to develop between the two. Sure they were both perverts and got along for the most part, but the way they handled their desires was far too different. While for Naruto this was simply a thing he did on the side until he got a girlfriend to satisfy all his sexual urges, Issei made perversion a way of life. With Issei being the open pervert that he was it often resulted in getting into troublesome situations and oftentimes Naruto had found himself guilty by association when caught around him.

Personally Naruto didn't care much about his public image, but when the problem at hand is something along the lines as the entire female kendo club chasing after you with bokken there's definitely a problem. Eventually they ended up drifting apart and Issei made new friends with two other open perverts like him, Matsuda and Motohama. Naruto had tried telling Issei that the two were no good, but Issei dismissed his concerns as him overthinking things.

Anyways currently Naruto was looking at his computer with a troubled expression, his previous sexual desires having been set aside for now as he read the message in front of him. Previously he had been looking through an adult site when he had accidentally clicked on an ad or something and gotten an advertisement for a game. Now usually he would have simply closed off the ad and been done with it, but the game had drawn his eye.

Basically it was about how you could play as the main protagonist of what amounted to an h-game. It detailed an organized menu and leveling system, dating elements, scene and scenario unlocks, and even a state of the art UI. It was a bit concerning that it didn't have recommended system specs for the game, but after a moment's thought he decided to wing it and give it a shot as it was free. If he didn't like it he could just uninstall it.

Clicking on the confirmation page he was taken to what appeared to be a registration page. Already having done similar things for other games he quickly filled it out and used the spare e-mail that he had on hand for sites like this and he was set.

Maybe it was browser based.

Just as he was thinking that, a bright light suddenly flashed across his vision momentarily disorienting him before he saw the screen fade to black and a strange looking red magical array appeared on the screen.

Upon seeing the strange array that looked like a portal to hell he frowned.

'Fucking malware'

He tried to press Esc, nothing happened. He tried hitting the home button, still no reaction. Glaring at his monitor he moved his hands towards the keyboard as he prepared his ultimate move…

Ctrl-Alt-Delete

The spinning demonic red circle was still in place.

"Fuck"

He thought his antivirus was pretty good, but apparently either this little monster was even better or it was custom made.

'Good thing I keep all my stuff backed up just in case'

Just as he was about to unplug the computer, the array faded and another light flashed across his vision. His computer returned to normal, but now he was far more shocked than when he thought his computer was being raped by a virus. Because currently floating before his very eyes was what could only be described as his stats.

"What. The. Fuck?"

He had a stat menu, he actually had stats just like a game. What the hell was going on?

Learn about monie.

He continued to look at the mission screen for a second longer before closing his eyes taking a deep breath and calmed himself down. He was just tired and was hallucinating because of lack of sleep, if he simply closed his eyes and went to bed…

He could still see it when he closed his eyes.

"What the fuck!? I mean what the actual fuck is going on!" he shouted in alarm as panic settled in

The text followed his vision and even if he closed his eyes he could still see it – floating there in the dark. It was like it was imprinted straight into his brain.

'Magic is it magic!? I'm sure no computer virus can do something like this…maybe that weird looking circle from before cast a spell on me. Yeah that's it, it's a spell. Hahaha…' He thought to himself as he laughed aloud looking the very picture of madness.

Slapping himself he found it to still be calmly floating before him, utterly unmoved from his sudden doubt of reality.

"Okay, I just need to calm down. I'm pretty sure I read a manga or light novel with a similar premise as this, this tutorial thingy might explain what's going on so all I need to do is play along for now." Naruto convinced himself before looking at the mission screen with an odd expression.

He continued to stare in silence as he got his thoughts in order.

So far he knew that it had something to do with the game and that his current predicament was related to that weird magical circle that appeared. Either way his stat menu was interesting, particularly the listed perks Hentai Protag and Divine Vision. Could those two in particular explain his current situation?

Maybe that hentai protag perk was what set all this off and that divine vision thingy was what allowed him to see things like the menu. Or maybe the hentai protag perk was also responsible for being able to see the menu and divine vision was something else.

Quickly he found himself calming down as he went about looking over things as if it really was set up like a game. In the end he decided to do as stated and start up the tutorial.

For a second he didn't know how he would go about accepting the mission before a prompt appeared.

To utilize the menu system verbal or telepathic commands are required for input unless an accessory device is in use. Verbal commands are recommended while in the midst of battle while telepathic commands are recommended otherwise in order to not attract attention.

He was startled, he had barely contemplated how to accept the mission before this message prompt popped up. It seemed to have read his thoughts, maybe that's what it meant by telepathic?

With newfound eagerness and steadily growing anticipation he decided to test out his theory…

Mission 1 – Accepted

"That is so cooool~!" Naruto cheered with a megawatt grin on his face, at first he was too busy freaking out to properly appreciate the situation but now that he thought about it, it was insanely cool. It was like his life was suddenly turned into a game and given one of his perks was Hentai Protag it was sure to be interesting.

"It's like getting a superpower" he thought to himself just as he noticed a checkmark appear next to the point in mission asking him to learn how to navigate the main menu.

Truly into it now he wanted to figure out to properly work with his new ability.

"Let me see the second point is…leveling system."

Just as he said it a new message prompt appeared as he was once more taken to the stat menu.

Our unique leveling system does not work on the basis of fixed stats per level increase, rather upon acquiring a certain amount of affection or completing a scenario, mission, or milestone you can be rewarded love points proportionate to the difficulty of the completed task. Be forewarned that love points while obtainable from receiving affection is randomized and is dependent on the luck stat for if it will drop or not when receiving affection. Larger amounts of affection also increase the chance of receiving a love point.

Naruto frowned, the message was through but a very important point was currently eluding him. What the hell were affection and love points?

Affection is used to make purchases in the Affection Store and allows you to increase the different facets of your Charm. Affection is earned from engaging in positive and meaningful interactions with others. Affection is derived from the goodwill others hold for you. Hurtful or cruel actions can make your affection level decrease. While you can derive affection from someone keeping you close to their hearts – you earn more through direct interaction with others.

During romantic interactions you may see the affection multiplier appear, keep your partner in a good mood and the multiplier will increase as will the amount of affection derived from interacting with them. Be warned however the combo multiplier will reset if you perform an unwanted action or say something off hand. It is recommended if you want to learn more about affection to initiate an interaction with someone in order to experience affection first hand.

Well affection seemed pretty straight forward minus that bit about there being a combo multiplier for it, rather for him love points seemed a lot vaguer as they seemed to be specific to his ability.

Love points are necessary for increasing your stats. Love points can be earned through missions, scenarios, and through milestones. Love points have a chance of being awarded upon receiving affection.

Love points increased stats. Now that might seem simple if it were in regards to a game, but considering they were talking about the real world that meant it would apply to him directly. This opened an entirely new dimension to his new ability, couldn't he potentially have super strength if he increased his strength enough? How would an increase in intellect affect him? Would he be smarter or would it be easier to understand information if he increased that stat? Instantly getting love points shot to the top of his to do list.

Seeing a checkmark appear next to learning about the leveling system he decided to go through the other points promptly in order to get the affection and love points that he would receive upon completing the mission.

'Perks'

Perks are skill based abilities that can be acquired through achieving a particular milestone (achievement) or through completing a certain event that fundamentally changes you as a person. Perks have various different effects and benefits. Caution – there are some perks that also have negative effects such as becoming exceptionally strong during the night only to become weaker during the daytime.

Pretty straightforward and not too unlike other games he had played before. He supposed that most of those immunity and sexual perks came from being the hentai protag and gaining this game like ability. Though that grayed out Greater Demon Container (Sealed) was a bit disconcerting.

'Achievements'

Achievements or Milestones is an action or event marking a significant change or stage in your development. These usually award possible scene and scenario unlocks, love points, monie, and depending on the circumstances large amounts of affection. It also has a chance of unlocking new items in the affection shop. Perks also have a chance of being awarded from achieving certain pivotal milestones in your development. Be warned that certain milestones award direct stat points rather than love points.

"Ohhh~"

He had thought love points were amazing but achievements were even more so. From them he could get love points, affection, and even perks. There were a few terms in there that he wasn't familiar yet, but he knew enough to know that achievements were a very good thing to get. Another check mark appeared.

'Scene and Scenario unlock'

A different menu came up, on it was multiple grayed out boxes with empty labels.

This is the scenario page, in it you can follow the events that have occurred in a given scenario and purchase new scenarios. Scenarios are stories or plotlines following a series of multiple events, they cannot be performed more than once per instance and offer decent rewards per chapter completion and a large reward at the conclusion along with an achievement milestone.

It was a quest. That might be called a scenario but it was definitely what amounted to a quest.

Another menu came up, this one having a single box with a label under it near the top followed by numerous other grayed out boxes below it. It looked like a gallery page.

This is the scene page, in it you can view the scenes related to a particular location or person. For a location the scenes unlocked is dependent on the action performed there, be it a fight or a date. It has the ability to provide boosts if you have the scene unlocked prior to performing an action there. For instance you are having a fight in a park you have unlocked the initial scene for, you have a chance to unlock a new scene by fighting in the park and also will receive a buff while in the area.

On the other hand when a scene relates to a person it is dependent on your relationship with them. You can unlock new scenes with them by advancing your relationship with the other person. From a scene detailing a date at a coffee shop, to having a sexual interaction with said person. You have the option to relive those scenes by simply selecting them and if your affection with that person is high enough at the time you will initiate the instance.

Also be aware you can view unlocked scenes on any digital device you own, however it is set up so that if anyone other than you tries to see them they will only see a video clip of kittens at play.

'That's almost adorable, however I better be careful in the future if I ever am looking at a scene with a sexual scenario on it and get 'excited', others will only see me getting hard over a bunch of cute little kittens playing around. That just doesn't look good.'

Another checkmark appeared and he grew excited seeing there was only two more left to go before he got his reward.

'Affection store'

The menu changed to a shop setting, it having a mature seductive feeling to it. It kind of reminded him of an adult site with all the pink and black everywhere to be honest. Looking over the inventory he knew that first impressions were often all that one needed.

For instance the first thing he saw was a butt plug tail – it all went downhill from there. Half the inventory sold items that looked like they were out of an adult store and the rest seemed to strike a middle ground between conventional and romantic. Most of the items seemed geared around getting girls or having sex with them, even the clothing menu that actually had stuff for guys seemed to grant specific boosts for picking up girls or going on dates.

I mean for god's sake, there were socks that increased your sex drive! What the fuck!?

'There's an entire section dedicated to BDSM and S&M. Not only that there are items that can cater to almost every fetish, you can make a girl an anthro and even chose what animal to splice her with. I am both amazed and scared of the implications.' He thought as he continued sifting through all the stuff available.

Amidst all the weird stuff there were some really fascinating little items that seemed really cool, like a water gun that dissolved clothes and glasses that could see in the dark. He just needed to keep away from some of the fetishes in the affection store and he would be golden.

Just about everything but male clothes was currently grayed out though…

The currency it required however was what surprised him, he had assumed that the monie that had been mentioned thus far would come into play at this point but the affection store only accepted affection as the main currency. That was weird, if affection was the main currency them what was monie used for?

As a gift for visiting the shop for the first time he was given five mints that increased his charm by 2 for 60 minutes. A checkmark appeared next to the point concerning the affection shop and he was more than eager to inquire about the next point and get his prize.

'Monie'

The menu changed to something that he hadn't even heard be mentioned so far. The Conversion Shop.

Monie is a currency unique to you. Its main use is to be taken to the conversion shop and exchanged for another currency. As it is you can convert it into two different currencies; affection and Yen.

The unit conversions are as follows;

100 monie = 10 affection

100 monie = 1000 yen

It remains the same regardless of differences in quantity. Though there are limits to how much monie you may convert to real world money at any given day, there are no such limits for converting monie into affection.

Be warned that yen can't be changed into monie and neither can affection. Also once monie is changed into any of the other two unlocked currencies you won't be able to change it back.

"For real!? You mean I can make real money out of simply playing along and completing missions and shit? Seriously!?" Naruto shouted aloud in surprise

If that was the case this changed everything, as that meant he could actually live out of simply completing missions and earning achievements and the like. I mean this tutorial took him what? 5-7 minutes? Yet he was going to get 1000 monie! That was 10000 yen in less than an hour!

His excitement only grew at the message that appeared afterwards.

Mission 1 Completed!

Awards:

+1000 monie

+2 love points

+400 affection

First mission completed – Milestone achieved

Award:

Scenario Unlocked – The Darkest Night

1 achievement earned – Trophy Viewer has been unlocked

Not only had he gotten his reward but he had also achieved a milestone achievement and unlocked a scenario!

He looked towards his stat menu only to find that while affection and monie had promptly appeared in his stats, love points had yet to be distributed.

Naruto Uzumaki – The Protagonist

Strength – 10

Intellect – 10

Agility – 10

Perception – 10

Charisma – 20

Endurance – 10

Luck – 8

Plot Armor 0/100

Love Points 2 (+2)

Affection 500 (+400)

Monie 1000 (+1000)

Achievements Unlocked – 1 (+1)

He wanted to check out that scenario that he had unlocked as well as the new trophy viewer but he decided to prioritize and allot his love points in his stat column. After a brief thought over the matter he ultimately used the two stat points to square out his luck as that single digit number was bothering him. Also from the explanation higher luck would allow for an increased chance of him receiving a love point through affection. That and he knew that a little luck could go a long way in life. I mean who hadn't ever wished they could increase their luck?

At first he had thought about increasing strength or intellect simply to hopefully receive what he imagined were immediate and tangible benefits but he refrained from doing so. He wasn't going to be fighting anyone and intellect wasn't a pressing concern as he was by no means lacking in that aspect to begin with. So with that intellect and strength were put on hold and agility, perception, and endurance were also deemed unimportant given the situation as he had no real need for any of them, as again he wasn't fighting monsters here but going to school.

In reality when all the fantasy was trimmed away what he needed most was charisma, intellect, and luck. Strength and the other three survival stats could be useful to a degree but not as much as those three would be to someone like him who didn't live during the warring states period. Though the idea of increasing his endurance until he was invincible was tempting he could not see any real world applications for it beyond living through getting run over by a truck. He wasn't keen to become some sort of superhero after all.

Charm was his highest stat at double his average of 10, he supposed it likely had something to do with the hentai protag perk again as he never imagined himself to be twice as charming as an average man. Either way as his highest stat he felt no real urge to increase it further, especially since he had those mints he had gotten from the store that would temporarily increase his charisma by 2 for 60 minutes if he needed it.

Intellect like he said before while potentially useful wasn't a pressing concern.

Luck however was his lowest stat at 8, moreover it could potentially show its worth in numerous ways. In a game setting it wasn't always the most skilled player that emerged triumphant, but the luckiest. While a skilled player may grind for dozens of hours for a single drop, a lucky player may come upon it on his first try. Luck could potentially outclass skill and experience if given the right circumstances.

"+2 to luck"

Verbalizing his command he observed as the love points dropped back down to zero and his luck increased to a very satisfying 10.

Fortune smiles upon you – Your luck has increased

You have reached your current cap on the luck stat, raise your other stats across the board to the next milestone to increase your cap. Next milestone 15.

Naruto grew wide-eyed, he hadn't imagined the possibility of stat requirements. Apparently it was a way to prevent someone from being completely skewed towards certain stats. He supposed that it was to encourage a more balanced character. Apparently all of the stats had different caps set up in correlation to the others, for instance luck was capped at ten but he was still allowed to increase any of his other stats including charisma which was at twenty. It was possible that the main stats could all go up to maybe 20 to 25 without stumbling into a cap lock.

Though that charisma stat was likely under the effects of the hentai protag stat so it may be a little bit different than what he suspected.

He supposed he could try tinkering around with the stat menu for a bit to see if he could figure out some more info on stat caps, but he was far more eager to look upon his newly unlocked scenario.

"Scenario – The Darkest Night"

His view switched over to the scenario menu only to be startled at the contents of the scenario.

"W-what is this?" Naruto said with a startled expression as he looked on wide-eyed towards the description of the scenario. A chill creeping up his spine as his pink world took a much darker turn.

Timed Scenario – The Darkest Night – 3h 12min 42sec remaining

Mission 2: The Darkest Night – The Beginning

Stop Katase's suicide attempt

Rewards:

Katase

Title – Mortal Savior

Difficulty: SSS

AN: This takes place prior to Issei becoming a devil so certain events have yet to transpire and certain people have not yet to fall into their respective roles in the series. Moreover this story is AU so expect differences from the original series.

Also the reward at the end is for the mission not the scenario. Things like love points, affection, and monie are usually rewarded at the end of the scenario as a lump sum rather than per mission instance.
