Shiren

Shiren is the character who appears in the fourteenth episode of Samurai Champloo Misguided Miscreants (Part 2) although he was referenced in Misguided Miscreants (Part 1). He is voiced by Erik Daves in the English dub, and Ken Narita in the Japanese dub.

History
Not much is known about his backstory, other than the fact that he was friends with Mukuro, and knew Mugen. It is implied that Shiren had feelings for Koza. Shiren is indirectly referenced as the mole who knew where the government ships were, though not by name in Misguided Miscreants (Part 1).

In Misguided Miscreants (Part 2) Shiren makes his full appearance, and he and Mukuro make a deal to get the money and Koza, while Mukuro distracts Fuu and Jin. Shiren and Koza are trying to get the money when Shiren meets Mugen. Shiren attacks Mugen, but Mugen easily kills him. Since Mukuro and Shiren were the only two people ot know where the money was, Koza doesn't have the money and is left alone.
