The first time I read this, right then I knew that this would be a long, [very] tiring and tense journey.
All the characters are annoying, especially the main character. Thank ChardiBSlays for represented what I wanted to spur almost with impatience.
On the other hand, I always have a thing for villains, a handsome psychopath who can control other people's mind.
Matsumune much like Johan from Monster and that's why I like it-- not in a sense how they brutally heartless. It's just that they can see the other side of naivete. They've been hurt and even in different conditions, I was in that position to feel. They justify and they live by that principle. Also, I'm happy that the heroine this time is a little better than before. I don't like Ibuki in meddle things, in an annoying way of hers.
Really, if I think about it negatively it came from how Kanzaki Yuuya presented his pawns. I try to accept his ideas, but the logic doesn't always work here. It's shounen in seinen's clothing. The world building that sails between heaven and earth, hell and heaven, lives and dies. I followed this only to guarantee the conflict that made me curious.
