While so far I haven't been too huge on this arc, I really liked this chapter. Seeing how Bakugou has grown, and seeing this great teamwork, is really cool!
I'm not sure if the "why man" is the guy behind all this, in fact, I don't think he is. When they do find him, regardless of their possible involvement with the petrification, it should be very interesting and I'm looking forward too it.
I'm really happy that there is more of this, it's a really interesting story.
It hurts when you know that they are killing people even if they are not staying dead.
