Intro
In the Kagari household, there are things that have been passed down for generations.
Records regarding the Mononoke. A genealogy engraved with the names of successive heads.
And, a single sword.
He, who has been by Guest's side since childhood, might be like an older brother. Or perhaps like an older childhood friend.
Or maybe, he is something else entirely.
Regardless—as of this very moment, Guest has become the new head of the Kagari family.
Shiranui bowed his head quietly. He wore the same gentle, soft smile as always.
