Sera Himeura
Sera is an ib with "explosives" ability, she can summon any explosives that exist on earth. She is an otaku with no friends who enjoys anime and manga as well as being a hero, trying to save the world. Her father was hit by a truck and died, the driver tried to avoid a cat and died in the crash as well. She ran away from home when her mother brought another man home. Sera could not blame anyone for the death of her father, thus could not find an "enemy." When she found a clear "enemy" (Kuro's Beast) she thought of it as a blessing.
