Roza

Razo was good friends with Hiru, and they enjoyed going to the beach to get tans and check out girls. After he used some sunblock he got from a pink-haired girl, he turned into Roza, and she spread the sunblock on Hiru to turn him into Hira. Such is life. She is one of two protagonists in Tanning Lotion."'I found some really nice suntan, for free!' - Roza is appreciative of her device of transformation"
