I personally think that this anime is underrated. I liked the art style, character setting and character development though the sound effects were nothing out of ordinary. Considering that it has 12 episodes only, I think the story progression was decent as well. I liked how every character had developed with the flow of the story and how the story was not following and orienting around one character only but all of them. I'll be looking forward to the next season~ ( I liked the tringle obsessed guy xd and I somehow can relate with tenma with the whole being a hard headed and kind of arrogant guy)
