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.
Yureka
Lost Saga is the most popular game out there and Lotto and his team are at the very top. One day he finds the ID card of another player, and by using this card, he finds out he can play as another character. He guesses that the card is hacked...but he uses it anyway. After a little fun messing with his friends, Lotto retrieves his own ID. But the events he set in motion result in the character whose ID he found, Yureka, an AI, accompanying him and his friends.
