But when Miyuki arrives at Tokyo, a man tries to take the boy, and given the boy’s reaction, it looks like abduction. Miyuki gets the boy back, and makes a run for it by car, but the guy pursues in a black sedan representative of the Yakuza mafia.

One of them, named Shou-kun, is a large snake which takes a liking to Miyuki, and hijinks arise when the duo returns to Bokuto, and the girl finds out Shou-kun has gone missing!

But this time the guy who has been responsible finds a baby that was neglectfully locked in a car. The mom goes into a panic when she comes back and finds her car broken into and the baby missing.

A police officer comes out of retirement to help out with things in Bokuto Station.
