Sin Dragoon Coronation(赤龍帝の七星兵器庫シン・ドラグーン・コロネーション, Shin doragûn koronēshon), also known as Red Dragon Emperor's Seven-Star Arsenal, is a specialized technique used by Ichijou Tsukino from the Highschool DxD: Яe-birth continuity. By "channeling" and "linking" the Evil Pieces from his fellow peerage members, Ichijou can change his Scale Mail armor into seven different forms based on the individual abilities of his comrades.
