Dousetsu Inuyama

Overview

Bears the "chū" (忠) bead of loyalty; his birthmark is on his left shoulder. His father was killed by rival lord Uesugi Sadamasa, making him hell-bent on revenge for the sake of his clan. In addition, he is Hamaji's half-brother. His mother was assassinated by Hamaji's biological mother (his father's second concubine), who became jealous due to her inability to bear a male heir. Particularly during the beginning of the series, Dōsetsu is ruthless, selfish, and a reckless loose cannon in the group. (Source: Wikipedia)
