Ojima Takeshi is a Nothing Burger character whose potential is unrealized because he is : 1. Not a an actual character outside of Hiroaki, and 2. Because his creator is anti-recovery and cannot write for shit.
I hate Ojima, I really do! He is no one! He is not a person, not a character, not anything if he is not with Hiroaki and that is so BORING! I don't even LIKE canon HiroJima! I only really like the HiroJima that the FANDOM has made up in their heads !!
Ojima never gets a chance to be someone 'cuz he's been delegated to being Hiroaki's accessory (QUITE LITERALLY SAID IN THE TEXT ITSELF), to Hiroaki's development, and because there is always the convenient excuse of him dissociating when he could be doing literally anythign else.
I love the idea of Ojima connecting with all of the cast in such an odd but real way.. His interactions with Chiba are like. Perfect. I think..
