Akihito Koyuke

Akihito Koyuke is a Shinigami and the longest serving member of Seke Miyamoto's L'Obscurite, besides Seke himself. Before defecting from the Soul Society, he served as an unseated member of the 1st Division, as well as one of the Kamui of the 22nd Generation of Hakuda. He was one of the few Kamui after the 20th Generation that wasn't actually a Captain, claiming that he chose to remain so low due to any higher level not appealing to him at the time. Despite this however he did eventaully stand in as the Captain of the 1st Division, and Captain Commander of the entire Gotei 13, while Shigekuni Genryusai Yamamoto was in the Royal Guard; however, he still took direct orders from Yamamoto himself during this short amount of time.
