Gema is explained to be the guardian of Dejiko and Puchiko. Essentially he is a floating yellow balloon that is always upside-down with very small eyes and mouth. Creator Koge Donbo once joked that Gema was the best character because anyone can draw him. He ends his sentences with gema. He can shoot darts out of bamboo sticks; but they have little effect on anyone. 

Di Gi Charat is a series of shorts created as advertisements for "Digital Gamers", a store in Akihabara. The series follows Dejiko, princess of Di Gi Charat planet, and her companions, Puchiko and Gema, as well as Dejiko's rival, Rabi~en~Rose through daily ordeals they encounter while working at Gamers. 
Princess Di Gi Charat came from the planet Di Gi Charat given only a cat cap and an outfit to disguise herself. Unfortunately she came with no money, only her guardian Gema and friend Petite Charat. Luckily the three stumbled upon a manager of the store Gamers, who offered them a home if they worked at the store. However Di Gi Charat is a selfish young girl who wishes of becoming a star.

Tiffany Lynn Grant is an American voice actress who is known for her English-dubbing work with the former ADV Films on such anime films and television series as Neon Genesis Evangelion, in which she voiced the character Asuka Langley Soryu. Grant is also known for portraying Nojiko in One Piece, Altena in Noir, and Ryoko Subaru in Martian Successor Nadesico. Although appearing in ADV titles, she was an independent contractor, not an ADV employee. Grant currently works at FUNimation and Seraphim Digital.

Grant enjoyed her role as Neon Genesis Evangelion's Asuka so much that she briefly reprised the character in the radio plays and fan-produced anime derived from the fanfiction series Neon Genesis Evangelion: R, as well as cosplaying as Asuka (in Asuka's familiar red EVA-02 plugsuit and her school uniform) at anime conventions.

She was married to [Matt Greenfield](https://anilist.co/staff/101497/), director, co-founder of ADV and also a voice actor. They divorced on January 4, 2018.
