Duel Masters LOST: Gekka no Shinigami

After a duel that nearly costs him his life, Win receives a Crystal Card from Crista and learns that it may be connected to the memories he lost. He and Niika head to a card shop seeking answers while Tokyo is shaken by grotesque incidents in which victims have their hearts removed. Behind the crimes stands Kyojiro Kokujo, the man feared as the Black Reaper, who wields a forbidden power called Assimilation. The mysterious card, Kokujo's attacks, and Win's missing past begin converging, pulling him into a battle where victory is no longer the only goal. Win needs an answer that can tell him who he was and what Kokujo intends to do with the memories surrounding him.
