Tsubaki Inoue

Tsubaki is a kind and level-headed girl, contrasting how peculiar her life is. For years, what's now her body had been a forgotten corpse, until one day she woke up. Upon digging herself out, Tsubaki terrified a local gravekeeper but quickly formed a bond with him, and he adopted her as his own. In spite of poverty and her condition, with his guidance, she blossomed into an outgoing and adventurous researcher with a knack for uncovering the truth.
