Rin Kairou (凛灰狼, Kairou Rin lit. Frigid, Ashen Wolf) is a Presas known for always being a loner due to her arrogant and prideful nature, never being around the company of other Presas, or anyone at all, but rather ignoring them, and as such never showed any compassion or aided her race, being hated by most Presas who know her as a result.
