Let's Go! Tamagotchi is an anime series focusing on the lives of Mametchi, Memetchi, Kuchipatchi, ChaMametchi, and their friends. The series premiered in Japan in December 2007, while an English dub was uploaded by Bandai in December 2008. It was originally uploaded a week before the release of the first movie in Japanese.

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 analyzing various events in Gun x Sword and mocking the themes displayed. They are included on the DVDs.

In a world on the verge of a great disaster that began five years ago, heroes who, with the help of a device called HxEros, use the power of Ecchi (H) and erotic power (Ero) to save the planet from libido-devouring monsters! Enjou Retto and Hoshino Kirara are childhood friends who have drifted apart from each other. One day, they're caught in a battle against a "Censor Bug" that feeds on human's sexual energy to evolve. After successfully taking down the enemy, they join a group of heroes like them, using the erotic power of the HxEROS force to fight off monsters. (Source: MU)
