KONOSUBA -An Explosion on This Wonderful World!

Megumin is a gifted young wizard from the Crimson Magic Clan with one overwhelming ambition: master Explosion, the powerful spell once used by a mysterious figure who saved her life. Rather than spreading her studies across different kinds of magic, she commits herself to that single destructive technique. Her pursuit takes an unexpected turn when her younger sister discovers a black kitten in the woods. What first appears to be an ordinary pet is connected to something far more dangerous—the awakening of a Dark God.
