Fumie Oshiro (大城 文江)
Fumie is more famous in the Internet by her nickname - Kawaii-ko. More than a million of people have subscribed for her main Youtube account, and about 1.2 million of people are also the subscribers of different off-topic channels. Because of this, she is often paid by different companies, when she adverts their production, and that boosts her self-esteem. Nevertheless, she is too proud to be a "purchasable creature" and never accepts intentional requests for advertisement. She is the oldest one in her class, but she doesn't take much responsibility, although you can always trust her words.
