Yuna

Yuna is a fifteen-year-old girl who lives by herself. She became socially withdrawn at age twelve of her own choice to play World Fantasy Online as much as possible. After Yuna gave them 100 million yen, her parents left her to her own volition. They only return home whenever they ran out of money to spend, causing Yuna to secretly move out into a luxury apartment to hide from her parents. There she spends nearly her entire day playing World Fantasy Online and spends the remainder on eating and sleeping.
