A Delinquent Became My Apprentice

Urara is an ordinary high school girl with a natural affinity for cats—and they love her in return. Seeking comfort among her feline friends, she heads to her usual secret spot, a hideaway where she can spend time with the many strays that gather there. But on this particular day, her peaceful refuge is interrupted by Izumi Hyuga, a bloodstained delinquent who appears before her with an unexpected request: he wants to be certified as a "kitty master" and become her apprentice.
