I haven't read the manga either, but the anime left me feeling emotionally unstable. If you're going through a bad time, it's not recommended, especially if you're someone who gets attached to the characters. 😆 The plot is too good, even for me, who's not a fan of violent themes. I was hooked from the first episode and would watch the anime again... but I'm not that strong, haha. 😭
P.S. I'm a fan of the ending! 😭
