Yureka

Yureka is an AI who accompanies Lotto during his adventures. She was created by a hacker to give him an in-game alibi in case he'd encounter a problem. She seems childish and naive at first, but over time she learns a lot from her fellow adventurers and becomes a person who will do everything to protect her friends. Endowed with strength and great speed, she fights with the help of two short swords.
