Hideyoshi Sarutobi

Known affectionately as Saru, this mischievous character is a close companion to Nagasumi and is frequently depicted with monkey-like, lecherous tendencies. While he serves as a loyal protector to Kai, his devotion is often driven by a desire for wealth rather than pure altruism. At times, he adopts the persona of the "ero-sennin," an eccentric hermit who emerges to provide comedic, perverted wisdom to those around him during pivotal moments.
