His expertise extends to hot springs, where he maintains specific standards regarding bathing etiquette.

He decisively intervenes to rescue Magoichi when the latter struggles against an armored invader, marking their first meeting and forging their connection. This action establishes the foundation for their subsequent alliance against external threats.

He possesses the rare Dragon Eye ability, a trait shared only with Magoichi among the characters, signifying a special capability within the narrative. His knowledge encompasses international affairs, particularly concerning potential European invasions, driving his efforts to protect Japan.

His narrative role intersects with Magoichi's journey as both confront foreign invaders threatening Japan. He interacts with members of the Saika Ikki, notably through Hototogisu, who serves as his shinobi while remaining part of the mercenary group. Hototogisu displays unwavering loyalty to him, devoid of personal ambition.
