  1. before the final episode next week, I solemnly apologize for muse Asia admin and whoever still genuinely love this anime especially in Japan🇯🇵 for how too many global homophobic normies especially in my country backlashed this anime without rational reason back then simply for nothing but Kinosaki character concept back then to the point where they even misuse global norm to justify their lack of deep understanding for the difference between fiction and reality and especially the cultural roots behind every genre and story type of anime and manga including this kind of otokonoko character concept which already exists in early 2000s long before local anime fanbase in Japan🇯🇵 being tainted by too many global normies and elitists like today

  8. would have hated if the end was just that intro of new woman (badass sidekick!) but glad there will be one more ep. hope it will be a nice end so that it feels like a proper series. if there is a s2, it should start nicely also

  27. Man who knew an anime about a toxic weirdo trying to find his wife was such a fun time. Gero is genuinely such a cool guy and all of the characters were so fun and not annoying. I like that he's OP but not to the point where he doesn't know what a struggle can be and its nice that he has dependable friends to rely on when things get tough. Also, its funny to think that Gero's poison is a gentle one that weakens the body in a big way and robs somebody of their senses and feelings but only temporarily enough to subdue them.

    I feel like the story had a good balance of action and comedy and while it stayed in its lane in a safe way, it did it in an entertaining way. Definitely a show I would recommend to a friend or even a family member. lol.
