Best bro is my one true king, Arthur Pendragon. Despite being barely flesh out as his OG story, Fate Prototype is yet to be done, and only his prequel which details him as him just Mr. Knight Guy, his story is interesting from what little tidbits we do know. For one, he knows Roman. And another, he killed a Beast more than once, and is hunting it down once again. Lastly, it’s implied that he’s yet to actually die based on his trial quest, as he still has something he needs to do. Not to mention, compared to the stoic Arturia, he’s less held back by his past, and is actually a rather happy guy.
Best waifu is Medea. Underneath all that witchery, betrayal and using others for her own means is an insecure girl who is afraid to trust others again. Scared of love and yet yearning for it, I just want a happy ending for her. I don’t even mind not having a Medea route in any game, just give us something where she’s happy with Kuzuki or whatever. Oh, and Rider Medea with the Golden Fleece, please. Christmas event main character material right there, what with her throwing whatever crap at couples because she’s bitter.
