齋藤 千春

A friend of Momoko. She is a cheerful girl who always seems to be at ease. While she admires Momoko's aggressive attitude, she is also a good advisor for Momoko, who has many unexpected problems.

She is also an author of erotic doujinshi and has a great interest in sex. She is open to all kinds of erotica (yaoi, yuri, and regular stuff).

She seems to be doing research by showing Momoko what she has written, but in fact she enjoys seeing Momoko's reaction. When she writes, she wears glasses.

Her usual calm and natural atmosphere disappears and her eyes become sharp when focusing on her work. She is an impressionable young woman with an ear for music. However, she is not very good at love or sex.
