Well, I'd say that this anime is like Shakugan no Shana but... perverted and absurd.
The female protagonist looks like Shana, more adult but with small breasts like her, red looong hair, tsundere, she even dresses a green school uniform when she gets into his high school, has fire powers... and falls for the weak male protagonist, who is patient with her and likes her even when other girls are after him.
The art is great and stuff, the opening and ending are enjoyable, the other characters aren't at least annoying. This anime isn't really special but I liked it anyway.
