Yūshirō Shihōin

is the 23rd head of the Shihōin Clan and the guardian of its sacred armor.

Appearance
Yūshirō is a young, dark-skinned boy with black hair, which he keeps in a thick ponytail. He wears white, fingerless gloves that extend to his elbows, white shoulderpads, and a black garment that covers his torso and legs with a white band wrapped around his waist.

Personality
Yūshirō cares deeply for Yoruichi Shihōin, having gathered many items to help her when Yoruichi contacted him after so many years of separation and tearing up upon learning that she left early. In conversation, he is very polite, bowing toward and profusely thanking members of the Gotei 13 for taking care of his sister upon meeting them for the first time in several years. He is also somewhat impulsive and oblivious to his surroundings; after entering Wahrwelt, he immediately takes off after sensing his sister's Reiatsu, only to nearly fall off before discovering he can't make Reishi footholds.

The Thousand-Year Blood War arc
After Yoruichi Shihōin leaves for the Soul King Palace, Yūshirō leaps from building to building in the Wandenreich City while telling her to wait up. Soon afterward, he finds Kisuke Urahara and the Visored and realizes that Yoruichi left without him. When a tearful Yūshirō explains how he gathered many items to help his sister, Urahara consoles him by stating that they will still be of use to them. Later, when several Shinigami arrive at Mayuri Kurotsuchi's laboratory, Yūshirō greets Suì-Fēng and thanks her for taking care of Yoruichi.

Soon after, Yūshirō, along with the Gotei 13 and Visored, enter the Royal Realm, only to find that it has been remodeled by Yhwach. Sensing his sister's Reiatsu from afar, Yūshirō immediately takes off to go meet up with Yoruichi, only to nearly fall off the city after Renji Abarai catches him. Yūshirō then moves out with the Gotei forces and Visored to reach the enemy's stronghold.
