Kyouichi suspects one of his fans is having trouble getting by, so he asks Makoto to go check in on her and her young son. Makoto’s mother takes an unexpected interest in the situation as well, and they find there’s more going on than meets the eye.

A woman abruptly commissions Makoto to get revenge for an attack that crippled her brother. But the "beast" who attacked him hardly seems savage, so Makoto decides to dig a little deeper on this case.

Now on the run from most of his former friends, Makoto has to use all the resources he has left to piece together who's causing so much trouble in Ikebukuro. Chances are, it's the same one who seems to have a personal grudge against him.
