While fooling around in the snow, Natsume and Nyanko-sensei run into Gen, a forest guardian who lives inside a statue. Gen tries to take over Natsume's body, but instead takes over a snow rabbit that Natsume had made. Gen pleads with Natsume to help him find an evil spirit who destroyed Sui, his guardian partner, and Natsume agrees. But it seems Gen isn't telling everything he knows.
Tropes associate with this episode:
- Cooldown Hug: A literal case since Sui's body is so hot that Natsume nearly died. Gen's tackle and his words manage to calm her down, though.
- Demonic Possession: Gen originally wanted to possess Natsume, but he instead landed in the snow bunny next to him.
- Foreshadowing: One night, Gen snuggles up to the snow rabbit that Touko made. Since he and Sui were built as a pair, he's gotten so used to having a companion.
- It's All My Fault: Gen blames himself for not being able to save Sui.
- Red Eyes, Take Warning: Both Sui and Gen have red eyes, signifying that they are or are becoming vengeful spirits.
- Snow Ball Fight: Natsume and Nyanko have one in the beginning of the episode. Nyanko becomes embarrassed when Gen tells them that he saw it.
- Suicide by Cop: After nearly strangling Natsume, Gen begs for Natsume to kill him.
- Unusual Ears: Gen's physical form has bunny ears. It makes sense since he possessed a snow bunny instead of Natsume.
- You Can See Me?: Gen asks Natsume this as he emerges from his statue.
