I figured I'd add an alternative for Sakura to summon if she doesn't pull Medusa being Lotara Sarrin the admiral of the World Eater's flagship the Conqueror both as a good choice for a Rider and still adds in that extra girl for the harem if you want to go that way.

I'm calling it now: Kodai is this universe's version of Big-E. He seems to know of Chaos and Deamons, and he's in command of a shadowy organization that has knowledge of the supernatural.

Good story

I know he has Avalon which makes it highly likely he will summon Saber but given his soul is in a weird twisted sort of way tainted by Chaos could he summon Salter or since the Grail is fully willing to screw with people have him summon Luthor that would be an interesting situation if I saw one. Rin summoning EMIYA would be fine but with her connection to Shirou another Space Marine would fit as well maybe armed with a heavy bolter no Primarchs though as one of them is way too much overkill and arguably not human like a normal Space Marine. Sakura summoning Medusa is perfectly fine as that's another girl to the harem though Shirou is showing a hatred of divine/supernatural beings in general so maybe not.

you like happy endings then why the hell do you Write and read warrhammer lol but loving the story so far

Okay you have my attention let's see where this leads.
Also nice to see Kiritsugu, leaving out some small but very important details.

Maravilloso como siempre

Good story. Didn't read the Warhammer fic that inspired it, but i'll do at some point later.

A small harem is always objectively better than huge mega-harem. That way the waifus aren't just immediately forgotten and glossed over whenever a new one appears.

Awesome chapter I look forward to the future chapters you bring forth.

Is this obvious one Bazett? If I remember correctly the association had 2-3 masters. Bazett who was killed by Kotomine shortly after summoning Lancer, Casters master who pissed her off and she killed, and whoever else Caster killed to get the spare comand seals to summon Assasin. Others were Illya with Breserker, Sakura with Rider, Shirou with Saber, and Rin with Archer. Archer should be a hoot to see him react to this completely different Shirou. I'd check the story 'Thats Hell You're Walking Into' to see what I'm talking about.

Glad to see that the story I started has grown to such a size. Indeed, I should call Zahariel a miracle worker with what I am seeing, from the lil' kernel of idea I posted on Spacebattles ;-P

To Bagrat: Gray is a canon character popping up in the El-Melloi files series.

Dope

Just found this story and I’m really enjoying it. I’m glad I picked it up despite knowing nothing about warhammer. Im looking forward to the holy grail war and how it will be different.

This was fantastic! The mystery (heh) continues to grow and the situation with Bazett is resolved well. I've never heard of Grey, is she an OC or is she from some source of canon?

Don't forget you can watch the Lord El Melloi case files anime for more context on how to write for Waver and Gray. Good story by the way. I cannot wait to read the next chapter.
