Aki Kuga

Aki is a childhood friend of Kyohei and a powerful seki who controls the kakashi, Kuramitsuha. He was quietly serving his sentence for the massacre of Kuga members, up until someone told him of Kyohei’s departure for Tokyo. This prompted him to escape his confinement to confront his old friend about the same “sin” they are guilty of and to stop him from living life as if nothing happened.
