   Summary

   On the mountain where he grew up, Kokoshibo--the ferocious Upper One--finds a shack with two injured boys. Boys who just so happen to perfectly resemble him and his long-dead twin, Yoriichi.

   He doesn't miss him. He doesn't.

   But he takes in the twins, saving their lives and keeping them safe.

   Because they are his, and he will not let them go.
