alright so like, spoiler alert. tokiomi here is the father of tohsaka rin and also a powerful magi. essentially his goal was to summon a servant--he was excessively pleased when gilgamesh answered the call--in order to win the holy grail war; however, his plan (as in being a magi, they have very specific ideas on things) was to sacrifice all seven servants that were summoned to open the 'great grail'. so he was gilgamesh's original master and gil liked him for a while, trusted him even. so when kirei told him what tokiomi was planning, his faith in the boring old guy was pretty much shot. essentially, gilgamesh grew bored of tokiomi after a while anyway and went on to start bothering tokiomi's mentee, kirei. so gilgamesh comes from somewhere later in the fate timeline, he's been with kirei for a long time. his feelings towards tokiomi are pretty resentful, he's really very happy with his new master. so you can take him from anywhere, obviously not his actual death which sucks cause i don't think anyone would be able to fix him from having his spine severed LOL but i mean if you can find a way, please do it? cause he'd be super hating on kirei and also really ticked off at gil for not defending him. and it'll be great.
man there's a lot of feels to be had here. seeing as how enkidu can be alive here. now, he was gilgamesh's first and only friend; he was the one thing that gil really, really treasured. he was sent by the gods because gil was getting too powerful, so enkidu was formed of mud and clay and his task was to defeat gilgamesh back when he was ruling uruk and amassing large amounts of wealth and basically mistreating his people. so these two had a great battle wherein gilgamesh basically depleted his arsenal from the gates of babylon and enkidu used a great portion of himself up trying to fight back. eventually, they came to an impasse and decided that they would make better friends. essentially, enkidu opened gilgamesh up a lot, even though he was still pretty much a prick. long story short, gil loved enkidu in some capacity, but they were THE best of friends. after gil rejected a goddess, she told her father to kill them and, since enkidu was made by the gods, he perished. gil absolutely mourned his best friend and was really never the same since.
more spoiler alerts. so here he is, the shittiest priest you'll ever se. i love kirei and gilgamesh times a thousand, i think their relationship is complex and interesting and they are The Ship™ that makes me wanna die. so, obviously, i would love kirei for the kotogil ship because its great and they've been together for like 10 years now. so gilgamesh found kirei way more interesting after a while, tokiomi grew boring to him, and he started to deflect onto kirei. he feels some kind of kinship with kirei since he's also a dark, twisted fuck. gil is really hedonistic and gives into all sorts of desires and pleasures, and he wants kirei to basically give into that. when kirei turned on tokiomi and killed him, gil couldn't have been more excited about it. so they formed a contract after that. so anyway, like i said, their interactions are great. i'd prefer if kirei was taken from around the same timeframe as gil, somewhere in their 10 year span of being contracted. because of the lack of the grail's existence, all servants have physical forms here now, so basically, kirei can't really control him as effortlessy with his command spells anymore, but gilgamesh will still probably do whatever for him. so, since they've been together so long, they've 100% started some kind of relationship, there's no way they weren't fooling around before. so obviously you can come talk it over with me and we can hash out details, but i neeeeed a kirei <3
so i only put three characters in here, but those are the three i really want; and honestly, i'll even take enkidu and kirei over everyone else. tohsaka rin would be nice to have around, since she knows gilgamesh and kirei was meant to look after her. saber would also be great because of gil's former obsession with her. so, honestly, anyone else from fate/zero or fate/stay night. its been a while since i've seen either series, i refreshed a little bit so i could write gilgamesh better, but i'm still a little rusty with his interactions with other characters. i just know that saber and rin would be great, but OBVIOUSLY i'm not gonna turn down anyone! caue gilgamesh is a piece of shit and getting him to interact with other servants and shit is A+
