Since being accused of using his powers to cause the fire that took his family, his face's habit of tensing up into a bizarre smile when he gets nervous has earned him the derisive nickname of "devil". He joined the Fire Force to achieve his dream of becoming a hero and saving people from the fear of the flames, as well as uncover the truth behind his family's death twelve years ago.
Though a newcomer in the Special Fire Force, Shinra has posed a challenge to experienced members of the force and has even defeated a Captain. Being a Fire Soldier, Shinra is experienced in rescuing people and is strong enough to carry four people out of a building. While he mostly relies on his Ignition Ability in combat, he has exhibited skill in ordinary fighting as well, being able to pin an opponent to the ground and break their guard with a sturdy kick, as well as being capable of defending himself from ground-breaking attacks.
