Guest has washed up on an island inhabited only by little boys!!??
Komorebi Island—a mysterious island that doesn't appear on any map. The island is home to only small boys, with about 100 of them living there. 🏝️ No one knows where these boys come from. However, they barely age at all. 🧐 The boys living here range from 2 to 6 years old. They wear matching sailor outfits and act as a group. The island is mostly covered in forest, but at the foot of a large hill, small houses stand in a row. 🏠 Each house is colorful and cute. It's unknown who built them (the boys handle the repairs themselves). In the center of the island is a mysterious spring where sweets, food, toys, and daily necessities well up (they only appear when the boys ask for them). ⛲️ Everyone goes to collect supplies periodically. They spend most of their time relaxing or playing in the sea and mountains. For some reason, communication lines, water, and electricity are all connected. Each of the 100 boys has their own personality, and there are all kinds of kids. Despite that, they are well-organized. (They have no surnames, and the boys themselves don't know who their parents are or where they came from.)
