In a charming village surrounded by rice paddies and bamboo forests, there lived a delightful character named Mosu. His story began during the Starlight Festival when a magical spark from a firework ignited a barrel of mochi, bringing Mosu to life.

Mosu quickly became the village's heart, bouncing through the streets and leaving powdered flour in his wake. The village children adored Mosu, following him on adventures and learning to appreciate the magic in everyday life. Even the grumpiest elders couldn't resist his warm hugs. As time passed, Mosu remained a symbol of joy and adventure, reminding everyone that extraordinary friendships can come in unexpected forms.
