Lenalee, Lavi, and the others have finally arrived in Japan. However, when three Level 3 Akuma appear, the group decides to hide rather than risk fighting them.

Allen continues to train with Fo in order to revive his Innocence, without much improvement. Some members of the Asian Branch start questioning the necessity of keeping Allen within their base.

Despite their best efforts, Lenalee and the others are unable to avoid the three Level 3 Akuma pursuing them. Just when they think they have no choice but to fight, an unexpected development occurs.

A Level 3 Akuma whose dark matter holds the power of decomposition has invaded the Asian Branch base. As Allen still cannot activate his Innocence, Bak and the others try to protect him.

Even though Allen's body is half decomposed and he still hasn't been able to revive his Innocence, he returns to the Level 3's location in order to save Fo.
