Enjoji, Kei

Kei Enjoji is the main character of Kizuna. Since he is not the legal son of a yakuza group's chief, he must leave the main house. After departing, he meets Ranmaru and falls in love with him. Although Kei is not the chief's legal son, a rival gang attempts to kill him. They fail in this attempt but nearly kill Ranmaru. Ranmaru does not believe he can walk again, so Kei tells him that he will serve as his left arm and left leg. Kei wants Ranmaru to recover because he loves him deeply. Ranmaru makes repeated efforts and eventually walks again. Thus, their love begins. Later, Kei finds his younger brother, Kai, who is the legal son. Kai and Kei do not get along well because Kai likes Ranmaru, but Kai lets it go when he sees how much Kei and Ranmaru love each other.
