Damn off to a good start. I was not expecting Shiro to summon Archer but in hindsight it makes sense. Was expecting Saber but Archer would be a better foil for him here. Curious to see which fate route is he getting these memories from. This story seems more like a deconstruction of Shiro as a character which is great to see so I'm not really expecting a romance but I'm rooting for my girl Saber ( or Archer the dude need stop and learn to love himself jk lol). Keep up the amazing work. Will be looking forward to this.

Good first chapter

Hell yes let’s see where this goes!

nice

This is confusing not in a bad way bit kind of interesting. The haphazard narration does resemble Shirous current state of mind. But it would help of you were more descriptive of where he is. Like small pauses to focus on the scenery or something to show that time has indeed passed and it's not all just happened at the same time.

Damn. Well, that's something I haven't read before. Good job!

It's so weird but the good weird y'know
Continue the story please

I cant believe you are my master?!

I'm curious on how Shirou and Archer going to do about the issue of mana here especially if Archer going to fend off against someone like Cu.

Continue, that's an order

Really interesting! Curious who Rin will summon, perhaps Saber?

now this is chaotic.
