i loved this anime. The plot is innovative, the characters are very particular both for how they were drawn and for their personality. I loved the colors they used. The only flaws are the 12 episodes that do not do this work justice. doing it a little longer, for example 24 episodes, in my opinion, more things could have been explained. we would surely know some mystery thanks to the special episode but I would have preferred it to be longer, everything would have been explained much better. a real shame as this anime is really interesting and one of a kind
