Marika is a calm, cute yet fiesty 10 year old Gothic lolita girl who somehow ends up in the mysterious town named Galihabara which she is soon told to be she can't leave until she comes to "like" science. She is very reluctant about it and put down by the whole idea, assuming she won't ever be able to return to her home due to her often becoming easily confused to the slightest equation. She's hinted here and there to take a slight interest. Scientific procedures are sometimes explained during Marika's meals, being the glutton she is.
