Ehhh, I liked the main character at first, but then something clearly went wrong. It seems that the developer just can't decide whether the MC will be normal and adequate, or whether he will behave like a retarded schoolboy. First he ran to his cocksucker to tell her that myths exist, and then he decided to introduce them to her. Completely ignoring the fact that it's like a very serious secret, ignoring the fact that it could jeopardize both her and those he revealed to her. Then his deduction and the detective's rational thinking apparently went out for a smoke, and he decided that one pleasant day in the company of vampires would completely change the mind of an old friend who had been told the exact opposite throughout her life. Again, he didn't care that by doing so he was putting those he loved and promised to protect in danger of death. It's also sad that we don't have a choice and we're put in front of the fact that the MC somehow finds the twins attractive without letting us skip them in any way. Simple, come on... It's not like they're even close to Suzu, Aki or Miko.
Also, here's a question. Is there any way to skip or get rid of Jun? I find that character incredibly annoying.
Well "his cocksucker" despite her looks is intelligent but regarded as a nutjob in the force.
Meaning first she would have figured it out on her own and second even if she snitches to someone it is most likely regarded as the rambling of a madwoman.
That is because she basically talks about many forms of Myth already, the harm it would do by telling her is minimal at worst.
Him trying to convince Ori by exposing his friends is risky, yes. But it was a sort of last-ditch-effort i.e. he had no time for a less risky and/or ordinary plan.
Plus keep in mind Ori is MC's childhood friend (not the players, though) meaning he is ... emotionally compromised.
Similar for the twins actually.
He was their babysitter, meaning he already has (or had?) a deep relationship with the two of them before the player took charge of MC.
Right now there is no way to skip Jun in any way.
Reason for that is that she essentially has a shadow of MCs heart alongside her own i.e. she is physically drawn to him.
She won't and can't accept a refusal from MC.
MC could certainly try to shoo her away in any form, but at that point she would likely revert back to a stalker.
Right now it is uncertain what the results would be exactly, but rest assured they would not be pretty.
If the story develops a bit more it is possible that MC can "free her of that curse" and let the human girl trapped in a myth world go free.
Keep in mind she is as old as the other girls in the class and her childish innocence could be a ruse i.e. she merely plays the clueless little girl to make others have pity with her and lure MC into having sex. I suspect that she is quite the informed, aroused and horny slut ...
