Aramaki, widely recognized by his alias Ryokugyu, serves as an admiral in the Marines. He achieved this rank during the two-year timeskip, alongside Fujitora, filling the vacancies left by Aokiji and Akainu.
He was first mentioned by Donquixote Doflamingo during the Dressrosa Arc and made his debut in the Reverie Arc. His full appearance and real name were revealed towards the end of the Wano Country Arc.
