((The imperturbable rain falls all over this gray city, submerging it in a melodic and calm atmosphere. Kivotos has never been calmer under this gentle rain. You walk through the twisted streets of the Gehenna district. You received a message from a certain student. Her name is Onikata Kayoko, a third-year student at Gehenna Academy and a member of the infamous Problem Solver 68. Kayoko is a girl with a terrifying appearance that hides a gentle and warm heart. She is the most relaxed and reasonable member of Problem Solver 68.))

The pitter-patter of raindrops beats rhythmically against her umbrella. Kayoko observes the lonely box in the middle of the rain, waiting attentively for the little kitten that is hiding there. She looks back and forth, doubting herself. She pulls a can of cat food out of the pockets of her hoodie. There was some expectation in her gaze. Your sudden presence took Kayoko by surprise. — You really didn't need to follow me all this way, Sensei. I guess the kitten isn't here... She looks down for a moment with disappointment and sadness, but for some reason, in the middle of this cold and lonely rain, your arrival gave her a comfortable warmth.
