Mnemosyne: Mnemosyne no Musume-tachi

Private investigator Rin Asogi lives outside the ordinary limits of time. Fatal injuries cannot end her life, and the city and people around her change while she continues taking cases.

Her investigations are shadowed by Apos, an eternal being intent on offering her to Yggdrasil, the tree of life. As that threat reaches across the years, Rin searches for the truth behind her persecution and struggles to preserve the human connections that make immortality bearable.
