Fire Thrower

Firethrower (火炎放射) is an esper power that scatter flames as if it is an extension to one's arm. It is possibly a variety of Pyrokinesis.

The only appearance of this power is in a 4-koma in the 2nd volume of the Toaru Kagaku no Railgun manga, where it is used by Kiyama Harumi through her Multi-Skill ability for the purpose of comedy. Due to its appearance in a 4-koma, it is likely the power isn't canon.
