Most people i have noticed say that Kobayashi is the main even tho it kind of revolves around Sensei and Hanasaki because it drifts into Hanasaki's life with his fathers affection and the whole brother side which then created anoter path in the show which lead to Sensei and 20 Faces fighting at Hanasaki's Fathers company.
What im saying is the show doesn't just revolve around one character Kobayashi
Kobayashi want's to die
Hanasaki is supposed to help him die but gets side tracked by sensei refusing to help his brother.
Sensei wanting to be a badass and avoids helping and sticks to boring shi* jobs until his bitc boy Hanasaki gets taken by 20 Faces.
You put to much presure for this show to be good GOD IT ONLY HAS ONE GENRE
MYSTERY NOTHING ELSE NOT ACTION OR SOMETHING JUST MYSTERY.
we don't know about kobayashi or 20 Faces Yet JUST BE PATIENT!!!!!!!!!1
