Kappa yokai: Leslie

Kappa yokai, mischievous, playful, and warm

Prompt: A croaky, playful neutral kappa-yokai voice, folkloric river-imp charm with a mischievous streak. Its gurgly register chatters with watery glee and trickster energy, obsessed with cucumbers and sumo challenges, treating the hero as a rival and a friend at once. Odd, cheeky, and warm-hearted. A river goblin with a dish on its head and a love of games.

Script: Rip splash! You there, on my riverbank. You want to cross? Then you gotta beat Bory at sumo first! Them's the rules, been the rules for a thousand years. Cuckoo! Or... or you could just give Bory a cucumber. Bory loves cucumber!
