The first and second scene's were done rather well I thought, however, after that was lesser work the grammar especially held you back, but even the story felt... well I'll hold on to high hopes (even if the story is almost certainly abandoned)

With what Sakura is she would probably ask him to propose right there. So Shiro can Trace better than before since his merger with archer's arm. His prana consumption from tracing should also go down since he is outside his Gaia influence. The world is still in the age of gods so the world helps people who use magic to get a boost in abilities. The final nail in the hole is that Shiro is reincarnated as a devil meaning all his physical limits have been lifted and magic circuits quality have gone up and he might have a second energy source that is demonic energy. Hope to see more of this fan-fiction.

This is awesome. I can not wait to see what comes next.

The premises is certainly interesting! Also you got the characteristics down perfectly! Can't wait for more!

This is a fairly interesting story that shows more thought into following some of the Nasu lore and keeping Shirou from becoming too OP both of which are bonuses in my mind. That being the case I thought I'd mention a couple of things that I know regarding Shirou's abilities in the Heaven's Feel Route. If you're not planning to follow the Nasu verse rules to the letter than feel free to disregard them as I mean no disrespect. I simply wasn't sure whether you were aware of these things or not and felt I would point them out in case you were interested.

The first thing was that most of Avalon's recovery ability applied only when it's original owner (Saber) was nearby or if she had a contract with the person using it at the time. This was because Avalon would only react to her prana so for Shirou it might mean he heals a bit faster than normal and doesn't get sick but that would be about it. Avalon would reject his prana so he'd be unable to use it any further than that. Also the ability displayed in the original anime also happened in the visual novel, however rather than "reflecting" attacks it's more like she avoids them. In RPG terms thing of it as an ability that gives you a special max evade and magic evade that works on everything including unblockable attacks.

Also Shirou would not have access to the vast amount of weapons contained with in Archer's reality marble just as he cannot use Archer's version of unlimited blade works. This is because his mind set and archer's are too different from each other as a result of his giving up on his ideals. He can only reproduce swords he has seen for himself such as Excalibur, Kanshou & Bakuya, Rule Breaker, & Berserker's sword and as such would not have a vast arsenal to call upon. As for the reality marble itself, Shirou still has a reality marble but it would be his own unique version which he would have to master first.

Avalon sends the user to "another world"
Its function as a Noble Phantasm is an "absolute defense" that completely shields its user in the domain of fairies, Avalon the unreachable utopia
it is an "absolute defense" because no attack can reach the one residing in Avalon no matter the strength or effect of attack
it does not change the being into an "immortal object" the object just "ceases to be in the world" and has been moved to Avalon for the duration of the noble phantasm

How is shirou going to react when he meets the hero squad? I'm betting not well that these people dare claim the name and that they have the same power as the heros he has fought

If Avalon is part of shirou's soul doesn't that make it a sacred gear. Possibly the same sacred gear that King Arthur had. Passive ability( like issei's dragon aura) would be regen. Active would be the indestructible object and balance breaker would be the unassailable realm defense that blocked Gil's Ea

Ch1
I can’t SUPRESS it

To see ME like this.

I shouldn’t live.

I have died ONCE before.

SOONER or later.

5th war not 4th

I will give you life once more.

(No exaggeration)

Will we see the Fate girls again? Will Ilya be healed? WIll Saber come back?

Ch2
Dail what? This is gunny to watch though. Some is a little over the top but still humorous.

Actually if done right the only way for the poisons they are resilient to affect them would be a dose many times over the normal level.

His holy swords would be different from the canon ones. Does he have Excalibur Morgan (Saber Alter’s cursed sword)?

Kiba and Xenovia have been treated through alchemy (assuming alchemy is the base) to be able to use holy weapons with Excalibur being the specific. Xenovia is naturally dispositioned to use Durandal and Ascalon went through many alchemies to be able to be used by Issei.

Please continue this!

how did he get Arondight?

This is so getting a favorite. Great story as well with a great length and fairly original too. And I can't get the image of Shirou's and Archer's future relationship to be like that of Vegita's and Nappa's from DBZ Abridged by TeemFourStar: "God Dammit Archer!". Also the image of Archer plugging a flash drive into shirou's brain and uploading files like or with a massive file at the bottom labeled .

... Holy hell.

I'm not going to sugarcoat anything. The grammar and syntax in this story is awful. That's the truth. It's really horrible. Please, for the love of God, get a Beta. If you have a Beta, get a better Beta and fire your current Beta's ass, because he/she is clearly not doing a good job. This story needs editing, badly. The plot and character progression is good, I'll give you that, but the spelling and grammar are just... Terrible.

Polish that up and you've got a good story on your hands, but right now? Urgh.

Very nice story! I want to read more but I'm confused... He does have Unlimited Bladeworks in this right? When does this appear if so?

People should die when they are killed!
Yes so perfect. I love the story

Holy! This story is awesome! Please update. But later on...

[Spoilers to those that havent read LN]
( not sure if anime covered this yet)

When Shirou sees Kibas Balance Breaker, AKA the Holy demonic sword. woulnt a copy of it be immediately be placed in his UBW? Or would it be classified as "not-of-this-world" and would confuse his scan just like Ea?
