Memories to Come.Beginning his journey in the Philippines, Yuu plunders an ability for seeking out other users and slowly starts taking the abilities from each user he meets, earning him a reputation as the dreaded "One-Eyed Grim Reaper". At a paramilitary facility that exploits adolescent ability users, he gains an ability to detect those with dormant abilities, using an illness-worsening ability to accelerate the abilities' development in order to plunder them. As he travels to various countries, he begins to suffer from extreme stress and borderline insanity from acquiring so much power, yet seeing Nao's flashcards prevents him from going haywire. Upon discovering the last active ability user in China, Yuu is critically injured from an attack by a male bounty hunter, but Yuu defends the young female ability user of courage before being recovered by Shunsuke. An amnesiac Yuu wakes up in the hospital back in Japan with Nao at his bedside. Nao informs him that they are lovers and expresses gratitude that he has kept the flashcards and their promise after all this time. With no other ability users present in the world, Yuu, Nao, Jōjirō, Yusa and Ayumi look forward to the memories they will make from now on.
