There's a new gang in town, and the word on the street is that they're acting as enforcers for a local business that treats its employees in highly questionable fashion. It's up to Makoto and one of said employees to uncover the truth.

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.
