Help me find a proper character name?

I'm creating a manga but i don't know how to name my character. I'm terrible at making names and i can't find one that sticks. I'm looking for a name like naruto or natsu, cause that seems to stick to me the most. What i mean is i want a name that begins with the letters N, A, and ends with the letter U. Also my character utilizes fire as a fighting method so i would like my name to have something to do with fire.(like how naruto means maelstorm because swirls are a recurring theme in the series. like how Natsu means summer and he uses fire in his fighting method.) I need a name that is short like two syllables but still sticks with the vibe of the character who is brash, simply. somewhat of an imbecile, but really kind hearted and protective of his friends. also I would like the name to be of asian backround(doesn't have to be, any language will suffice.) and please provide more than one name option. if you can't its cool. i know it seems like i went into too much detail but being an artist and being creative are important to me so i want it to be as perfect as possible. thank-you in advance.
