Di Gi Charat 梅雨スペシャル

Di Gi Charat (call her Dejiko for short) and Petit Charat (the cute little charat) come down to Earth, where they want to be idols, or something like that. Rabi~en~Rose (a random girl with bunny ears) decides they're in her way of becoming an idol herself. They all end up working at Gamers, where various otaku, children, and humanoid fingers walk in and act like morons.

Contains:
Gema no Sumika
Tsusode shiu Engekidan (ii ne!)
