In “Samurai and Ninja,” the multiverse-hopping Gavan Raiya (Kunai) arrives on Lambda Earth, where he crosses paths with the stoic android Gavan Bushido (Setsuna). The episode centers on Setsuna’s existential struggle as he attempts to understand human sorrow through a “crying support group,” leading to an emotional breakdown that triggers a high-stakes duel between the two Sheriffs. Their clash of samurai discipline versus ninja agility is interrupted by the discovery of a dimensional rift, forcing the rivals to momentarily align their blades against a growing inter-dimensional threat while Setsuna continues to grapple with his lack of physical tears.
