I have only read seven chapters as this many are posted online, but I will try to leave a proper review as no one as yet.

Story(7): Pretty good. A guy, Haru, has the power to burn anything, anywhere. He's basically a human torch but he can't control his power and causes many disasters. One day he accidentally burns his friend, Natsu, pretty bad. Even so, Natsu decides to keep all of this a secret because she's in love with Haru. 'The Secret Arsonist' becomes a problem in the city.

Art(8): This is the best point of this manga. I really like the art. Nothing else, it's just.. I like it.

Character(7): While Natsu is strong-willed and does anything she can to protect the one she loves, Haru is really weak. Like I said, I didn't read the whole thing, but up until this chapter Haru is a pathetic main character. He lets a girl protect him and keeps setting houses on fire. Even though he can't control his power and he's not doing it intentionally, it's still not ok. There's a chance he will develop and become stronger, so let's not lose hope.
About Natsu, she's a really interesting character. She protects the one she loves, act as if nothing happened for his sake but she still has her own secret.

Enjoyment(7): I had fun reading, it's refreshing.

Overall(7): You should give it a try.

Feedback is always welcome. =)
