Gun x Sword-san

Synopsis

These are a series of 13 omake episodes of Gun x Sword, tied in very loosely to the plot, with the characters as chibi puppets. The main characters are Wendy and her turtle, Kameo, who is the size of a human in this series and is able to talk. All the episodes seem to center around analysing various events in Gun x Sword and mocking the themes displayed.

They are included on the DVDs.
