About Aramaki
Aramaki, better known by his alias Ryokugyu, is an Admiral in the Marines. A former policeman from the Taya Kingdom, he was part of the World Military Draft that filled the two Admiral vacancies (along with Fujitora), caused by Kuzan's resignation and Sakazuki's promotion.
Ryokugyu was first mentioned by Donquixote Doflamingo in the Dressrosa Arc and debuted in the Levely Arc. His full appearance and real name were revealed near the end of the Wano Country Arc, in which he serves as a supporting antagonist.
Ryokugyu is a muscular man with thick and wild, dark green-colored hair that reaches to his neck. He appears to be quite tall, as he looked comparable to fellow admiral Fujitora, who stands at 2.7 meters. On his face, he has a somewhat pronounced nose and lips as well as a light goatee and sideburns; he has been shown smoking a cigarette.
Ryokugyu eschews wearing a shirt, going bare-chested and exposing the large green kanji tattoo "死川心中" (meaning "double suicide at death river"?) that runs down the left front of his torso. He wears a pair of black pants with small flower shapes (of alternatingly light and darker green shades) on the left leg, whereas the right leg has a few small tears. He also wears a pair of differently colored shoes, the left one being light-green and the right one black. Additionally, he wears a pair of black sunglasses over his eyes and the standard Marine officer's coat cape draped on his shoulders, which covers his otherwise bare back and bears the usual pure-gold epaulettes seen with other Admirals, plus green turn-up sleeve cuffs to again match his color motif. The entire inside of his coat is, in fact, not white (uniquely among any admiral seen so far) but green.
