Basically media like Tsukihime where the mc (Shiki) has a double life between interacting with vampires and school. Or fate, where Shirou has a servant and fights in the holy grail war outside of his ordinary life. Knk technically counts but idk. So what are some titles or VNs you'd recommend with this "mysterious" type of vibe to it. It doesn't necessarily have to be type-moon but extra points if it has alternate endings or a followup to it.
