The Demon Realm's Little Ones Save the World

Youyou is the Demon King's only child. She should have been the little princess adored by the entire demon realm, but reality is cruel:

The demon realm is doomed!

To avoid becoming a homeless little cub, Youyou is willing to do her small part to save the demon realm.

So she takes on the task her father gives her: go ask the lord brothers and sisters for help.

With the fate of the demon realm at stake, Youyou diligently sets off on her journey.

The Seven Lords of the Demon Realm are seven mighty figures personally appointed by the Demon King.

They have wildly different personalities and strange tempers. Some are proud and unruly, others cruel and violent, and only a handful of demons dare approach them.

Until one day, a little lamb beast arrives in the lords' territories...

The little lamb beast has snowy white, plump, round fur. Sometimes she happily bleats; sometimes she pretends to collapse and refuses to get up until someone pets her. Even the cruelest demons can't help softening around her and speaking in a sweet, high-pitched voice.

The little lamb beast's unknown species catches the attention of demons with ill intent, but soon they discover, to their horror:

The proud ancient demon, over three thousand years old, willingly lets the little lamb beast sit on his head as he patrols his territory.

The second seat, who goes berserk at the slightest provocation, calmly cradles the little lamb beast and lulls her to sleep with a gentle song.

The violent, cruel, and inscrutable third seat even knits the little lamb beast a coat himself, and gently scolds his subordinates: "If you scare my precious, you're dead~"

All the demons think the little lamb beast earned the lords' affection by acting cute, but only the lords know how important Youyou is.

The Demon King gave them power and security, while Youyou gave them warmth, endless potential, and a soul made whole.

They would sacrifice everything to protect her home.

With her by their side, they can do anything.

Later, the prophesied calamity arrives, yet the demon realm remains peaceful.

Youyou: "Dad, isn't the calamity coming?"

Demon King: "The demon realm's calamity is gone. Yours is just beginning."

Youyou: "?"

In the blink of an eye, Youyou becomes the new Demon King.

Youyou: "???"

Dad, that's not right, is it?

P.S.:

1. The female lead was not born naturally. She's a real little cub and can be mischievous.

2. My own worldbuilding, with a lighthearted, everyday feel.
