@KoLTo be fair, people like Hector and Odysseus (although he's quite an idiot when he's full of himself) are pretty cool. And Herk when he's not mad doesn't seem to be that bad-
Orite he murdered a lot of people offhandedly. Meanwhile Achilles is just a plain big jerk, Jason's a big ass, and stuffs. Their heroes are pretty messed up. The human women like the Amazons, Helen, Cassandra, Odysseus' wife and such were pretty decent due to their lack of screentime I think, but the goddess and dryads and anything nonhuman are usually full-on jerks. But that also applies to male nonhumans in the mythology.
Greek Myth is a mess, man.
Himiko...would definitely have a certain reaction to Tamamo as soon as she know who she really is. Maybe it's like squeeing when you meet your senpai in your reunion after you're successful, but since you're trying to save face you squee internally but then everything crashes when reality attacks and your senpai is nowhere near how you remembered them as.
Would be fun too since she's practicing profane magic on the side (which...thinking about it, would give some similarity to Tamamo's own witchcraft). It'd be like when you're going to meet your old senpai again but right now you're using drugs but then you later know your senpai actually was a junkie during the time you're away from them.
