"Awakening"

A parasite of negative emotions takes over the blue Matsu after a long time of bottling his emotions towards his brothers. One day he just becomes another person. Not the sweet Karamatsu Matsuno we all know and adore, but a cruel, savage, angry human being. What will happen to the brothers with Karamatsu in this state of mind? Who would bring him back? Would he ever be back to being his normal self?

Inspired by the song "Enemy" from Imagine Dragons.
