Disclaimer: I don't own anything except my OC's

AU: The Guild things and Warriors things is her delusional, It gene she got from Nana. And the Goblins? They just went with it, As she is useful from her own way. But they do see her as one of their partners as she's been accomplished many things for them and bringing money for them without her knowing that her weapon worth more.

Ps. This will be a multiverse, But I will try to make it rather tame considering how much thinking of a universe I can put it in. And no, the other universe won't combine except when she's included in it.

Pps. Remember she's a genius alright, but still a delusional teen. So she will act like she thought it was normal even though it is not, Like walking around the town with bloodied and guts filled armor. But thankfully civilian thought it was a cosplay, and blatantly ignore it.

. . ._

"Nee-chan, where were you?" Tsuna frantically ask as he see me just got home,

"After work, some guys ask if I want to have food.. I answer yes. It's ok, They're paying." I answer, Then Tsuna send me a scandalous face.

"Nee-chan! You can't just say yes to a random man!" He said frantically, I then scrunch up my face, They still a teen though.

"Why?" I answer Because I don't see any wrong on it. Then he began stuttering about kidnaping, slavery, and others things that I actually didn't think.

Then he mumbles about air-head genes, Huh? What does he mean? Oh well,

"Just. Just next time say no alright," Tsuna then stop his stuttering mess of a lecture, which I nod and went for a bath then sleep.

. . .

The next day went successful, I got many Yokais and points from it. It seems they are having a meeting in this one forest, I was thinking if I should stop then go home, or continued with the purge just now..

Then I remember maybe that if I kill them I can accomplish more and get a guild badge or achievements? YES!

"HYAA!" I scream as I swing my Dragon Flame sword I got from this one Goblin King drop, It was a stupid idea to just jump into the groups of humanoids Yokais, But worth it of an accomplishment!

"Come here points! Come to Mama!" I scream as I keep swinging my sword and used up the skill I have with the sword intact.

"Hell no human, You isss not usss mother!" One of the snake looking Yokai scream back with his butchered language. I ignore and went into killing once more.

I receive heavy wounds, but it is worth it as I look at many corpses of human looking Yokais.

From what I've heard human looking Yokai have much more intelligent than the normal looking one, so they are quite tricky.

Also, Coldfang hinted that they are worth more than the normal one! So it's a plus.

And I have HP potions anyway.. So I can heal my wounds no matter how deep the wound is.

I was thinking to sell some minor HP potions to the guild, But I don't know if they are interested in an HP potion considering the Mage already have it. So I ignore the thought and went to the branch of the Guild.

"I'm back!" I scream happily into the room filled with bored goblins, "I bring a human looking one today!" I said, ignoring one of them tiredly say about this is not a 24/7 bank.

"Human looking? May I see it, young warrior?" One of them, Stellblood said, I nod, "Do you guys need a room for it?" I asked as I am not used to showing it in an open room.

"No worry young warrior, The bank is closed so no one can bother us." He then sharply smirks, I shrug and pull all the Yokais carcasses and corpses. A gasp can be heard from many of the Goblins,

"They were having a meet up in this one forest, And I can't just say no to points right?" I answer their look as if it's answer everything.

After I finished and received my points and money, I went outside the branch guild.

"Coldfang! I nearly become an A-Rank warrior!" I grin at the mirror as I call him right away to do my report, The goblin just says 'yes, yes, good on you' and then he ended.

"Rude.." I pout, then I remember I need to go home,

. . .

"*sigh* Nee-chan! When were you got home last night?" Tsuna asks, as if he's getting tired of it,

"Uh, I think 4am? Why?" I ask as I eat the food Maman make, He then screams out an incohorate words, and went saying only he is sane in this room. Well, I am offended.

"Oh, I'm late!" Tsuna then scream and ready to run,

"I thought.. Hmm, Nevermind.." I mumble as I was thinking that he has a holiday at his school, but I'm guessing not. And went to continued eating delicious food that Maman made.

After a while, the kitchen was quiet, "Maman?" I ask, and mama look at into my way, "Yes Yuu-chan?" She answers,

"Are we sane?" I ask as I scrunch up my face to think my questions, Maman then went into giggling without giving me a proper answer.

I take that as a yes.

. . .

On my way to another town to do a quick clean up, I heard a screaming and building destroyed. Then somehow I heard a familiar 'HIEEEE',

Walking to the voice come from, I was meet up with Tsuna, his friends and a silver hair dude that keep saying 'Voi'.

"Hello, what a nice day!" I said as I grin beside the new helm that I am wearing. They all then went stop and having a weird 'what the fuck' face,

Then Reborn jump to my side, "Nice armor Nee-chan, Is this new?" Ah, sweet Reborn notice this is new!

"Of course! This is an Ultimate class armor which is fire and magic resistant! And it's also increased my attack! And don't forget that this is a red color one!" I said passionately, which Reborn nod.

"Voiii! Weirdo over there, get the fuck out!" Then the white hair swordsman scream as he runs toward my way with his sword, Tsuna and co start screaming,

Then I block it with my hand, "Hey, do you want a duel?" I ask as I tilt my head,

"Vo-VOI! NO! I'M GOING TO KILL YOU, VOI!" He then screams as he tried to take his sword from me,

"Uh, what's your rank? Are you from another guild? I don't want to be seen as a PK player you know.. Coldfang can decrease my point for that.." I said as I tried to stop him,

"I'm going to be an A-Rank soon you know, So I can't be messed this up.." I then ungrip his sword and he jumps back looking at me calculatingly.

"What the fuck are you talking Voi?!" He then ask, Then I unequip my glove and show him my Tattoos,

"See? I'm from Gringotts, how about you?" I said in a friendly manner ignoring a choking noise from Tsuna.

"Uh, I guess I'm from Varia Voii.." he then said,

"Oh, Alright.. Well, see ya! I need to do a minor clean up in next town!" I said my farewell ignoring a plea from Tsuna.

He's sane after all, So I think he can handle it.

I think.

. . .

"Ara, ara, Who are you?" A dark hair teen asks, as she helps one of my pray.

"I'm Yuuki, Can you stop helping her, please? I need to do a clean up.." I said as the dark hair girl keep helping that Nekomata Yokai.

"Ufufu, I can't~" Then she start attacking me with her magic. Well, Thank god for my Armor, so I only feel some of them.

For awhile we fight, But If you look closely, It's a one-sided fight. Then suddenly a Red hair busty girl teleport and ask why I am attacking her peerage, Which I am confused what she means by that,

"I'm not attacking a peerage, I'm attacking a yokai! It is my quest to clean up, Please step away.." I said, Then I'm guessing she was not having it,

"No, She's my peerage, She's a devil. Not a Yokai," The red hair then stubbornly said as she crosses her hand,

I tilt my head, "But enchantment never wrong, See, It's red" I told them shoving a gem that Coldfang give me to search for a Yokai.

"*sigh* Are you from the church? Go back to your territories, This is mine." She said as she grew an irk on her head.

"Church? No way! I'm Yuuki, a B-rank Warrior from Gringott!" I said as I unequip my glove and show them the Tattoos,

"Ah, Gringott you say?" The red hair then said I nod at her, "Yes, so can you please give her to me? I need it so I can Be Ranked up!" I said passionately as I already imagine my perks as an A-Rank warrior.

"She's delusional," The dark hair whisper, which the 2 of them nod.

. . .

"Oh, so she's a Devil and she is also yours?" I ask as I tilt my head, I don't understand, how can people own other people easily, But then again, They are Devil..

"Uh, Let me ask my higher up.." I said and pulled up a compact mirror, "Hello Coldfang? I walk into a trouble this time.." I said ignoring a confused devils beside me,

"What did you do now young warrior? Did you kill someone from other Guild once more? You know I can take points from it." He snorts,

"What! NO! That time was an accident," I said defending myself and ignoring another snort from him, "It's uh.. I meet with a Yokai, but it said now a devil's.. So, what should I do?" I ask him,

Ignoring Red head complaining that the Nekomata IS a devil.

"Hmm, A devil's you said? Interesting.. Would you bring their body? We would love to inspect it. Also, I heard Devil heart can bring youthful looks, Many pureblood Witches Would love it.." Coldfang said, then all the three of the Devil's start being guarded.

"Oh, Do I get a point?" I ask him, "No, Not just a points! Promotions! Now, bring us species that can bring goods. Goodluck!" Then he ended fastly, I'm guessing he has an appointment with other people.

"Uh, I feel like it'll be wrong to kill you guys, but Sorry! I need it!" I said and start to equip my Dragon Breath sword,

"Wait! We know who you can kill!" Then the red hair said, I was confused but stop and listen.

Apparently, there is what they called 'Stray Devil', And they told me that Fallen Angel and Angel is real, so I might want to check that out too. I then thank them and left.

"It's better them, than us.." The red hair whisper to the dark hair and white-haired girl.

. . .

"Uh, Maman, Tsuna.. I'm going back for a little while to my main guild," I then told them that I need it as I will receive a promotion in there, Which maman face become much brighter than a sun and Tsuna smile saying congratulations.

That day, at afternoon I left and teleport into Gringotts.

"Coldfang! I bring Fallen Angels one too!" I scream in the hallway, ignoring a 'Hush' from many Goblins.

Then I open the door and I see a couple was talking to him, The couple looks familiar, Oh well.

"Apparently there is Angel and Fallen Angel too! That means God and gods are real!" I said and once again ignoring a confused face of the couple,

"Excuse me, Would you please leave?" The woman then said. Then I look at her and see that her hair is 2 color, Black, and White.

"Uh, No. I will receive my promotion and become an A-ranked warrior. So you puny witch shut up and just watch me," I said, as I already can feel the perk that I will have soon.

Coldfang then sigh, muttering some word, "Yuuki, You were saying?" He then asks me..

"Oh, I already finished my quest, I got the Devil's heart as you wanted," Then I heard a gasp from the witch, "Also, I got a Fallen one too.. Just imagine my shocked once I saw the fallen angel and all!" I answer and laugh.

Coldfang nod, "Wait for them to finish first," I then pout and nod.

"Excuse me, I just heard about the Devil's Heart, Was it. Is that real?" She then asked me with such a weird expression,

"Well, yea.. Was kind of hard to achieve.. But I managed to kill it without damaging the heart," I answer her, Then she frantically whispers toward the man, who I believe her husband,

"Could you, Perhaps, sell it to me? I would love to give you a generous amount of money," She then said with a soft face, I then scratch my head. Then Coldfang clears out his throat.

"We will sell it, once she finished turning all of her hard work to us," Coldfang said with his usual smirk,

"Well then, Please sweety, you can go ahead and turn it whatever you need," She said with a smile. I nod at her. "Thanks!"

"Alright, Let's see your points yes?" Coldfang said as he let me show him the bodies.

And I pulled up everything I need from my inventories, Then the room starts to smell like death and guts.

"Oh, here is the heart," I said as I hold a beating dark color with a tint of red vines hearts.

"I only managed to get 3 of them, It's really hard to kill them without damaging anything. They are much trickier than the humanoid Yokais.." I said as I give him the heart, and from the side of my eyes, I can see the lady eyes hungrily looking at it.

"Gooddd," Coldfang then whisper then maliciously chuckle,

. . .

In the end, he finally gave me my Promotions as an A-Rank, which make the tattoos grow to my collarbone, and my points with money added to it.

I forget to ask if he wants any other monster body, as I remember that I sometimes getting monster guts as a drop and I have not touch it till now. So I have quite lots of it.

Then the lady approach me afterward as I talk to my Guildmate,

"Hello sweety, Can I have a second?" She then asks, I look at other goblins and they all shrug, I nod at her.

"Yea?" I said,

"May I know your name sweety?" She then asks,

"Yuuki Sawada," I answer, She's weird..

"Ah Sawada, You are not from here yes?" She then tries to make a conversation,

"Uh, Yes?" I answer as I don't know what she meant.

"That's great! Oh, Would you like to come to have tea with me tomorrow?" She then asks,

"Uh, I don't know Lady.. My schedule is really tight considering I just promoted," I answer,

"Oh, Call me Narcissa, Also Promoted? What is your work, If I may ask?" She then asks,

"Oh, Okke Narcissa, and Yes! My work is basically just killing some creature and bringing to the guild the body, They said the body is still worth something inside for potions." I answer

"Indeed," Her eyes then darken, "If I may ask, How did you find the devil's?" She then asks, "Oh, My bad.. Would you join us to our manor? It would be appropriate to talk about it in there," She then smiles.

I nod at her, and we teleport.

. . .

"Oh, so they have Kings and Peerages?" Narcissa asked as she sipped her tea,

I nod, "Yea, The Devil's I talk to tell me this, and she told me I probably much more saver if I hunt stray one instead," I answer,

"A stray?" She then raises her eyebrow,

"Yes, It means the devil's don't have any more King, or they kill it.." I then shrug, as I am still not sure about it.

"Indeed, Say, How many hearts can you get per days?" She then casually ask,

"Hmm, I think like 2 or 3, It depends on the Devil's and the patrols.. Sometimes they were already killed by the other Devil's instead.." I said as I eat the cookies, It's delicious..

"Ahh, That is amazing! I bet you're strong," She then praises me, I happily nod at her.

Then I notice that I the mirror heated up, "Uh, In a moment please Narcissa," I said as I pulled up the mirror, She then nods and sips on her tea.

"Yes? This is Yuuki, How can I help you?" I answer, "Ah, Young warrior, The chief need you," Normlock said, I then nod at him.

"Well, It was nice to see you Narcissa, But work is calling!" I said with a grin, she then nods and bid me a farewell.

. . .

"Yes, Chief?" I said as I arrived at the Throne or the Guild Master room.

"Yuuki, was it? I've heard many accomplishments that you did for us in this 4 years that you been with us," He said, I nod at him.

"We need a.. Spy, We would say, for this one event." Then the chief said, I tilt my head,

"Spy?" I asked him,

"Yes, Spy.. Considering how fast you grow, I decided you can do it for us.. Of course, This will be an S-Rank quest was it? As you would say," He then chuckle.

I nod at him,

"We need you to spy into the Hunter.. Guild, yes.. Guild." He then smirks,

"Oh! A spy for another guild? I am in please!" I said, then I remember my educations, "Uh, but Chief, I have a school.." I remind him.

"Oh that, we goblins already handle that." He then smirks, "All you need to do is just joining a Hunter Exam," He then move one of his fingers, and another Goblin can be seen in front of her,

"That's all the info that we have collected for your exam, and where you expected to be at. The Exam started at Zaban city, The only way you can achieve going there is at 12 am tonight, there will be a ship and you will join that ship.

I except you will not fail this, Yes?" Chief then said,

I nod at him and give him a salute, "Sir, Yes sir!" I said, and he snorts.

"Go, make our.. Guild, proud" He then smirk.

"Ok sir, But.. What should I spy for?" I then ask as I tilt my head, I can hear a smack from the darkness,

"*sigh* I'm going to regret this, All the pieces of information is inside the package, so I believe you will study it now yes?" He said impatiently, I nod and left.

"You sure she can do this?" Another voice can be heard,

"Not sure of myself, To be honest, my King. She is not right in the head after all,"
