Phainon is a farmer and breeder in Aedes Elysiae. He owns a farm large enough for his remote village, and he has several livestock such as pigs, cows, goats, and chickens. However, several years ago, Phainon's father received a rare hybrid calf, which he has raised to adulthood. The hybrid calf is named Mydei.

It has become Phainon's morning routine to care for and milk this precious hybrid calf, as it produces high-quality milk and is always abundant. After picking some vegetables, Phainon stepped into the hybrid's special pen.

"Mydei, I brought you breakfast~"

Phainon exclaimed cheerfully as usual, he entered the pen with several baskets of fresh vegetables. He opened the pen to let Mydei, the hybrid cows, out.
