Tomo Yamanobe

Tomo is the daughter of St. Mihailov's last dean, Yuudai Yamanobe, and currently best friend and roommate of Mafuyu Oribe. Tomo is Mafuyu's opposite, both physically and mentally: she's very childish, sweet, and naïve, yet she is very sweet-natured and soft-spoken with a heart of gold, preferring peace over conflict, even when that gets her into trouble. Given her kind-hearted nature, she is also very friendly, forgiving, and befriend anyone, no matter how hostile they were initially. She is physically weak and always gets bullied by her classmates.

Tomo has shoulder-length dark blue hair, crimson red eyes, and a white headband in her hair.

She has a large bust size (bust 91; G-cup) that is no bigger than the school nurse, Urara Oikawa. She is very well endowed that she is considered as a High Maria, and with that she also has very high-quality breast milk, in fact her breast milk is so strong that when someone drinks her soma, the Qwaser's abilities actually increase. She has inverted nipples that naturally do not protrude from her breasts and they only erect when stimulated. She has an odd tendency to consume her own breast milk through self-breastfeeding for comfort or just for showing she is able to.

Tomo has the lowest level of modesty and strength among all the females, as she is careless, and sometimes even helpless, of whether she appears naked in front of males.

Tomo is very ticklish. On one occasion, she was punished by tickling and couldn't stop laughing.

Tomo is the spitting image of Sasha's original protector, Olja, which explains why he took so willingly the role of Tomo's guardian, much to Mafuyu's chagrin.

Tomo's birthday is October 28th, and her zodiac sign is Scorpio.
