A man he’s only just met asks Makoto if he can help him figure out who killed his son five years ago. Thus begins some detective work for Makoto, which ends up digging up things that perhaps should have remained buried in the past.

As tensions rise between the G-Boys and the Red Angels, Makoto finds himself mediating from the middle as usual. But this time the situation is different, and the stakes become much higher than they've ever been.
