Bruh, Hachiya reminds me of goofy characters like Aqua from Konosuba or Satania from Gabriel Dropout. For those two, I often hear that their best feature is, with affection and no sarcasm, being "slightly retarded". Not only that, but he can act smug that approaches the likes of Uzaki or Nagatoro.
Because of this, I honestly think Hachiya has actual woman moments, and this is especially the case when he is crossdressing.
I predict that Hachiya will be the main heroine, and Hanazono will get the childhood friend debuff.
