A young individual encountered a kappa while on their way home from a shop. They decided to purchase it impulsively and named him Kaatan. Although the person had no prior experience with owning a kappa, they acquired a book that offered guidance on raising and training these creatures. The book contained several helpful tips for nurturing an intelligent and well-behaved kappa. However, implementing these techniques in practice proved to be more challenging than expected. Kaatan initially appeared to comprehend the instructions; however, he often forgot what he had learned or lacked interest in learning. Despite this setback, the individual remained patient and continued their attempt to transform Kaatan into a cherished pet.
