Natsu

Haru's girlfriend. In the present time, she is seen as cheerful and cute (she's the first in popularity polls in her classroom), being very dedicated to her boyfriend.


Before getting to know each other better, she was rather cold to everyone else, the reason of her being called "Fuyu", or winter, which is the opposite of her name ("Natsu" = summer).

She discovered Haru's powers while his hands were burning in the PE storage room and got burnt in the process. She ultimately survives, the doctors believing it is a miracle that she would live, promising Haru she'll keep his secret safe afterwards.

Natsu has a power as well. She shows Haru a fast recovery after he accidentally burned her on the school's rooftop; however, the burn marks remain (even though she showed Haru otherwise), so as of chapter 9 she harbors a yet unknown power.
