Soubi Agatsuma 我妻草灯

A n art student. He is a former student of Shichisei Gakuen (often translated as Academy of Seven Voices), a school for fighters where Ritsu Minami was his teacher.

As ordered, Soubi contacted Ritsuka after Seimei's death. He introduced Ritsuka to the world of fighters and sacrifices, and told Ritsuka he would be his fighter. Although Soubi's "true name" is Beloved and Ritsuka's is Loveless, they fight as a pair, which is considered taboo. There is also a severe loss of strength, and in Soubi's case, his marking bleeds in battle. Since meeting Ritsuka, Soubi doesn't operate under the Beloved name, and effectively abandoned it altogether.
