Kyougo Komiya is one of the students of Class 1-C and a member of the Basketball Club.
We do not know much about his personality, but according to Satsuki Shinohara, he worked extremely hard every night to become a regular player in the basketball club. So it can be said that he's a hardworking person at least when it comes to basketball.
Komiya often acts as one of Kakeru Ryuuen's henchmen as he was involved in Ken Sudoy's incident and followed the Ayanokouji Group on his orders.
