Ginrei is a large black fox summon exhibiting leucism, rendering most of his fur white except around his feet and inside his ears. This distinctive appearance marks him among Anrei Tendo's Kitsunin summons, and he holds recognition as the largest in this group.

His personality intertwines positive and negative traits, manifesting cleverness, playfulness, persistence, and keen observation. He strategically bides his time before acting, projecting an outgoing and effusive demeanor that draws attention while maintaining humor and resilience. Ginrei engages in mischief without severity, endearing himself despite trickster inclinations. Yet he may deliberately incite chaos or malevolent outcomes when situations demand disruption.

Ginrei employs heightened senses for efficient tracking and channels chakra into his limbs to immobilize foes, creating openings for Anrei or fellow Kitsunin. He demonstrates exceptional coordination with four other entities, devising and executing offensive-defensive formations that maximize his agility and limb strength. Using Yin Release chakra, he casts genjutsu by infusing chakra into his tongue during fox-like vocalizations, manipulating enemies for intelligence gathering or infiltration.

His bond with Anrei Tendo eclipses other connections, originating when he imprinted on her as a pup and solidifying lifelong loyalty. His genjutsu activation consistently relies on vocalizations paired with chakra infusion.
