Megaba (from the Japanese words for メガネ = megane, lit.eyeglasses and ばあちゃん = bāchan, lit.grandma) is the owner of the candy store Megasi-ya. Megasi-ya also sells software and metatags. She is a craftsman of metatags in Daikoku and a high level software programmer. She is also Yasako's grandmother, and the head of the Coil Denno Investigation Agency.

Imagine if the internet was 'projected' over the living world and you interacted with it using a portable device - glasses and visors which connect you to an augmented reality. In 2026, this technology becomes reality... 
 
Yuuko Okonogi moves with her family to Daikoku, home of an ever expanding tech network which makes up the interactive virtual world. Her grandmother runs an agency to investigate missing children who appear to have vanished from the 'real' world and entered the city's Dennou - literally meaning "electric brain" - a term used to differentiate between the virtual and 'real.' 
 
A hacker culture is emerging amongst the children of the city. Yasako is soon introduced to Isako, whose powers for hunting computer viruses known as 'illegals' belie an agenda that might have sinister motives.

Chapman's also jokingly self-deprecating about some of her past roles, as typically she's "the bitter woman who gets melted, put into specimen jars and blown up".    (source: Wikipedia)
