Ooumi, Megumi

Megumi Ooumi is a 14-year-old pop star and The Keeper Of The Book to a 6-year-old Mamono named Tio. She is frequently seen in video games or performing at concerts, yet despite this, she remains an ordinary girl.
She possesses a very kind-hearted personality and views Tio as a little sister, often soothing her fits of rage and helping to explain the world to her.
Megumi first encountered Tio when she found her injured on the docks. Initially, Tio kept harshly to herself when they first met, stating that Megumi would only get hurt by helping her fight off Mamono. They eventually started to get along, and Tio came to trust Megumi.
After being helped by Gash and Kiyo, Megumi regarded them as friends, like Tio, and swore that one day they would return the favor.
