Pyrokinesis

Pyrokinesis (発火能力) is the psychic power to create flames. The general term for this kind of Esper is Pyrokinesist.

In other works, Ignition Power (Pyrokinesis) is - as the name indicates - the power that makes possible to start a fire. Apparently, a "scientific" rationale for it involves raising the motion of a target's molecules through Telekinesis in order to ignite it. In cases were a fire is started when there is no combustible materials, not just heating power but there might also be a realization-factor involved.
