【Manga adaptation volume 7 and novel volume 15 now on sale from TO Books! Junior Bunko edition volume 7 releases on 9/1!】

A fantasy world where Western and Chinese cultures intertwine.

Born in a corner of that world, Ageha (鳳蝶), the only son of the Kikunoi Count family in the Kiou (麒凰) Empire, was doomed at five years old.

In addition to his severely overweight physique, he had zero allies.

To make matters worse, his suddenly appearing younger brother, Regulus, was apparently going to kill him in the future over the right of succession to the peerage...

His only weapon was the suddenly awakened memories of his previous life as a Japanese person: "cooking and sewing."

Amidst this, Ageha ended up raising his younger brother by chance, and --"My brother is super cute, isn't he?"-- before he knew it, he was completely doting on his brother!?

For his fledgling younger brother, he made educational toys by hand and even developed chawanmushi.

Mobilizing all his previous life's special skills and domestic abilities, he steadily improved the neglected territory!

His small steps even involve the gods and change the entire country—a territory management fantasy about young brothers!
