Fire Force Vol. 3: The Strongest Fire Soldier – Shinmon Benimaru (Light Novel)

Terror grips Tokyo as ordinary people, possessed by demons called Infernals, begin bursting into flames. It’ll take a new kind of firefighting team to tackle this threat. Enter the Special Fire Force – a newly minted, rag-tag team of firefighters assembled to take on spontaneous combustion wherever it occurs. The newest member of the team, Shinra Kusakabe, is a pyrokinetic who can ignite bursts of flames from his feet which give him superhuman power and speed. Can he and the rest of the Fire Force track down the source of this strange phenomenon plaguing the city or will it be reduced to ashes first?
