Seishirō (静止狼, Seishirō) is the current Lieutenant of the Eighth Division within the Gotei 13, and thus, the partner to Shisai Kyōraku. A stern, but compassionate man, who holds his Captain in check from the depression he has suffered throughout his life, Seishirō is an ideal example of a Lieutenant. Set with his own, unique attributes that differ him from common Shinigami, Seishirō is perhaps one of the most unorthodox Shinigami who is currently enlisted in the Gotei 13.
