The fanon kills me. :(
Gaia crushing projections is not a thing, Shirou can just willy nilly project stuff permanently.
I mean his 'workshop' has objects that were projected and stayed there for years.
Its only the reality marble that has a time limit if its manifested.

Decided to stick the legendary sword in with the fire-pokers.

The first bonfire is lit, humanity restored...

At that moment, inscriptions appeared on the floor, one of which read: forward of the bonfire, and then, praise the sun! What could that mean ..?

Sans is going to be in for a treat, after all he'll need to watch over a Battle model homunculus and Shirou with his Hero of Justice thing. Poor everyone. Also, will Shirou cook something? Because I want to see the monsters reaction to his cooking!

Next while we get to see what Kiritsugu is doing while his son has fallen into a mountain. I’m sure whatever he’s doing are the actions are a responsible, child friendly parent. Yes. Absolutely. Meanwhile, the underground tries to wrap their head around the concept, conception, and existence of a homunculus.

Interesting can't wait to see what happens next.

Shirou has more determination than Frisk does, given Shirou's feats of LITERALLY SHOVING A HOT IRON ROD AMOUNT OF PAIN EVERY SINGLE TIME HE WANTED TO LEARN MAGIC.

Also, Shirou's mundane projections have never been seen to actually stop existing without his magic fueling them.

And I'm going to be honest,
I kind of want every time that Shirou is pulled into a fight (and his soul dragged out) it doesn't produce a heart but instead, UBW just covers the entire area.
Because it'd make sense, UBW is Shirou's actual soul.

Plus... Flowey beating Shirou? ...

What?

We're talking about a Shirou with actual skills, right? What can a bunch of vines do to a bunch of swords? Shirou can just reinforce his body to the point he has a Rank E in everything and just chop these vines, man.

You know, I really did have sum serious doubts on this story, considering the mixed bag that is half of the whole crossover. I was, not entirely confident in its viability.

The crazy thing is, I was wrong.

This here is some gucci writing, and if I had to be honest with myself, it is almost criminal that it's not as apprecoated as it should be. The AU aspect may seem iffy at first, but it seems well thought of enough to not be a real problem, and oddly familiar for that matter...

It's only three chapters with not much diving into the meaty bits yet, but suffice to say that still got me intrigued in a good story. And I really hope it lives long enough to become just that.

I, for once, would be really interested with how thing will progress, like with the - seemingly either Sella or Leys - Homunculus maid, people usually don't appreciate the other characters enough in a crossover.

Gl boyo.

ha

It’s funny really. That despite every reset Flowey seems to ALWAYS forget about Toriel

I can't tell if Chara being attached spiritually to Shirou is a good thing for them, on a one hand there's literally no chance for Chara to be driven insane va. A geno route cuz that is anti-Shirou as all get out, on the other hand They are now stuck being unwilling narrator to the most stubborn, bullheaded, altruistic, and mentally broken person on the planet fuck Shirou gets a frickin Reality Marble thats not normal for a human there's a reason they're usually explicit to vampires.

Take your time, the important thing is that you have fun writing

Good fight between Flowey and Shirou, especially the conversation they had and what Shirou's reaction to the fact that a species of monsters who can seemingly use third magic(if he is aware of the specifics of them)especially since it entails the Materialization of the soul and the immortality gain from mastering it maybe similar to an infinite Determination being a property that keeps a human soul persist after death even for a short while. yeah pretty sure if Shirou goes through the game's true pacifist that he will gain that refuse death immortality hax.

pls. dont abandon this, I really want to see how Shirou develops and whether or not he has a red soul along with the reset power

And so shirou’s adventure in the underground begins in earnest!

One meter tall...?

Flowey?

That's a bit too tall.
I'd understand like a foot at best.
