Ryugato Yachiyo

A strange girl Reiichi encounters in the abandoned Shinjumachi.
She appears before Reiichi and the others amidst the town's strange occurrences, revealing that they are trapped in a “kauriyo” (realm of the dead) and that to return to their original world, they must find the town's deity “Ohako-sama”.
She claims to come from a special family and was sent to Shinjumachi under specific instructions, but...

Her dignified presence and blunt way of speaking often make her seem cold and unapproachable, but glimpses of her seriousness, politeness, and deep compassion can be seen in her actions.

"This is a “kakuriyo”—a place that exist nowhere, born between the realms of the living and the eternal. Me and you all have been lured into this world and are now its captives."
