Promise.Yuu wakes up in the hospital with Medoki, Shichino, Maedomari at his bedside. He learns of the permanent loss of his right eye and the devastating death of Kumagumi. Ayumi, Jōjirō and Yusa each come by to visit during his rehabilitation. Also, he encourages Misa to express appreciation for her parents while she still has a chance, being given this opportunity when Yusa host a television food report on their family restaurant. After Shunsuke explains that Japan will be involved in terrorist attacks soon, Nao suggests for Yuu to travel overseas to plunder the powers of all ability users worldwide, though this could risk his sanity. He accepts this challenge and confesses his love to her, and they make a promise that he will come home safely. She offers him to plunder her ability so she can live a normal life. He then plunders the abilities of Jōjirō, Yusa, and Misa, the latter of whom leaves behind a letter for Yusa expressing how much fun she had with them all. Nao gives some foreign language flashcards to Yuu, and he gives back her MP3 player as a vow that he will come back to her once the mission is over.
