Kazehiki! Voiced and Managed by くるくる数字
Released November 6th, 2015; Kazehiki is the ghost of a boy who died very young. He haunts the halls of an abandoned church afflicted with an eternal cold, and is constantly sleepy. He doesn't remember much of his past, other than his persisting faith in God; he acts as the priest of the church he inhabits, and prays every day to be lead to heaven.
Something I got wrong in my post abt Gekiyaku, is that there is a connection between her and Kazehiki, in that they were created to be duet partners! Any actual blood relation is left unclear, and the creator wants people to come up with their own theories on them. The only canonical notes of their relationship is that Gekiyaku's extremely clingy towards him because she believes him to be her little brother, but Kazehiki doesn't feel the same and is usually quite frightened by her.
