A

Biodata

Personality

A is highly sensitive to the significance of a tailed beast voluntarily speaking through its jinchūriki. When Gyūki addresses Kamizuki Yu through Killer B, A is shaken, recognizing it as an unprecedented degree of acknowledgment—possibly reverence—from the Eight-Tails toward Yu. 57

Relationships

• Gyūki — A understands the weight of Gyūki's voluntary address to Yu and interprets it as the Eight-Tails' highest recognition of him. 57
