Ko Ogino (荻野 コウ(おぎの こう), Ogino Ko)is a supporting character in the series. He is a former student at Shuchi'in Academy.


His middle school look is short hair that parts at the middle. He also has long eyelashes.


On the surface, Ogino appears to be friendly and attractive. In reality, he is cruel, manipulative, and a skilled liar and is a two-faced snake who was very condescending and patronizing when Yu Ishigami found out about his secret.


Ogino was introduced as Kyoko Ootomo's boyfriend. One day as he talked on the phone, Ishigami overheard his conversation. After a small talk, Ishigami deduced Ogino's cheating. Ogino tries to silence Ishigami by offering him something suggestive and distasteful involving his girlfriend that ended up with Ishigami beating Ogino up. In front of many witnesses, Ogino acts like Ishigami is Ootomo's stalker and thus makes Ishigami the criminal and acted like the victim.

Ogino broke up with Ootomo, and after that was forced to transfer out of Shuchi'in Academy when Kaguya revealed his crimes to the various VIPs who attended the school.

Series Appearances
