Character Profile: Seishiro Sakurazuka

Seishirou is a kind veterinarian, who becomes the Sumeragi twins' inseparable companion. He has some odd quirks, but always has a warm, teasing smile. He joins in with Hokuto in teasing Subaru about them getting married, but always laughs it off as Subaru blushes furiously.

Seishirou also is the Sakurazukamori, or the "Sakura Assassin". He made a bet with Subaru long ago, which entails the climax of the series.

X is about a final fight between heaven and Earth. The seven seals are mankinds last hope. The seven angels want to purge humanity from the Earth. Kamui, a young boy, holds the fate in his young hands.

When his mother dies, he comes back to Tokyo for the Shinken, a divine sword. Later on, the sword is stolen by Nataku, a synthetic human with no gender, and his best friend's father is killed trying to protect it.

When Subaru and Seishiro meet, Subaru lights the other's ciggarette. Then all hell breaks loose.
