I'm just writing this review to say that this show is better than the other reviews and ratings would have you believe. Sure, in the beginning it starts off as a typical isekai type anime harem thing, but it's not actually a harem because they're all just friends and the main character has brain trauma. Everyone seems to think that's a bad thing, too, but I think the way he emotes with his body instead of his words actually adds to his charm! The animation is actually really impressive too, way better than your typical cash grab isekai anime. It seems like the animators actually put passion into making this project. The ending also answers enough questions to leave me satisfied but leaves more than enough to make me look forward to season 2. This is not to say that this anime is the best ever or that everyone will like it, but by the end it turns into something genuinely interesting and fun, even if the first part of the series doesn't give that impression at all.
