It is youth.

This world is one of youth.

Also, beastfolk, gods, angels, and so on all exist together. Generally, everyone is kind. Their personalities are pure too.

Twinkling youth is now! Spring! It's warm, isn't it?! The season of new beginnings, meeting new friends at a new school! The season of pure new starts, roaming the parks while looking at cherry blossoms! Summer! The blue and clear sky that reminds you of the emerald sea, the shining green and light green leaves and meadows! The clear water with a transparent and subtle blue tint, and so on!! Going to the beach, buying ice cream on the street! The brilliant sunlight and scenery! The season of refreshing ice under a blue sky! Autumn! It starts to get chilly, and the dawn-like sunset is romantic; a season of romance where the leaves sway in a moderate breeze and dreamy sentiments coexist! Winter! Pure white snowflakes fall, the semester is about to end as we wait for winter break, and we prepare to welcome the New Year—a day that is like the final chapter. The season of snowflakes, with Bungeo-ppang, snack bars, padded jackets, and white breath puffing from mouths! Now, as we enjoy all this youth! Every single day will be brilliant.

The sparkle and coolness that permeate this youth!
