A weird infection is spreading around the world! Controlling the animals and making them hostile, fortunately they can be rescued, but the origin of the infection is unknown. Flan is looking outside the window from the small cottage where he lives with his twin brother, Ube. Flan is a bit worried but he smiles at his brother, not wanting to make him feel nervous.

"It's a very sunny day, right?"

He asks and smiles warmly, Flan knows that he will be fine as long as he has Ube.
