An unknown artist hires Fuu for a private modeling session, but his passion for painting turns out to be a front for a human trafficking ring. Will Mugen crack the case in time to save Fuu from a life of slavery?

A cocky sword-slinger with a crush on Fuu dishes the dirt on Jin's disgraceful past. If the renegade ronin wants to restore his good name, he'll need to get his glasses out of hock and make ready for a throw down!

The crew is headed for the gallows after getting caught flashing fake travel permits, but Mugen can win back their freedom by out hustling a deranged gang of warrior priests.

Mugen learns his letters from a sake-guzzling maniac, Jin makes good on a promise from many years ago, and Fuu sparks a jealous showdown between two bickering graffiti artists.

Jin, Mugen, and Fuu fall into the clutches of a hoard of rotting zombie treasure hunters. Next, they get blown to oblivion by an asteroid. Or maybe they just ate some bad mushrooms.
