**Dias**, a war hero hailed as the savior of his nation, is rewarded by the king with a fief — only to find it is nothing but a vast, empty grassland with no people and no homes.
As he stands at a loss, a girl with blue horns named **Arnar** appears. From that meeting, a colorful cast of companions slowly gathers, and life begins to take root on the barren land.
He builds his domain not with the sword but with the plow, not through war but through trust — a gentle yet stirring tale that begins July 10, 2026.
📝 魅力・見どころ・特徴 ネタバレ控えめ
01The thrill of building a domain from absolute zero
Zero subjects, zero buildings. Watching a village take shape step by step from a truly empty plain is the core appeal — a slow, building-game-like satisfaction.
02A lord who protects daily life, not a battle hero
Though a war hero, what Dias faces is cultivation and human bonds, not battle. A protagonist loved for his character rather than his blade gives the story a warm afterglow.
03The fateful meeting with Arnar, the blue-horned girl
The girl with blue horns met on the plains is the key that sets the story in motion. The bonds she brings turn an uninhabited land into a home for everyone.
04An ensemble of richly distinct companions
Beastfolk, merchants, children — people of different races and circumstances gather in one domain. It can be enjoyed as an ensemble drama where each person's story and growth intertwine.
05The 'reward' feel of domestic management plus fantasy
Fields you struggled to prepare bear fruit, homes are built, people arrive — a structure where effort is visibly rewarded. A soothing isekai you'll want to watch at the end of a long day.
06Opening theme 'Wonder' by CROWN HEAD
The forward-looking opening 'Wonder' powerfully pushes that first step from zero. A track that perfectly matches the exhilaration of frontier-building.
07Ending theme 'Yakusoku under the Starry Night' by Kaya
The ending gently accompanies the close of each day. With its image of a starry sky over the plains and promises among friends, it leaves a tender afterglow.
08Newcomers can start right from the anime
Because the story literally begins from 'zero subjects,' even those who haven't read the source can dive in without confusion — as if growing the domain alongside Dias.
💡 注目ポイント・展開予想 軽めネタバレ
The early arc will likely center on transforming the empty grassland into a place to live.
From the meeting with Arnar, exchanges with the beastfolk village will widen, and through trade and farming the domain will gradually take shape.
Because Dias carries the past of a national hero, the politics and neighboring powers around him are expected to become a highlight as the story advances.
🧾 これまでのあらすじ ネタバレあり
Here is the starting point: Dias, who distinguished himself in war, is granted a fief by the king as a reward.
But what he receives is a vast grassland with no people and no buildings — a literal 'zero start' with zero subjects and zero facilities.
In that hopeless situation he meets Arnar, the blue-horned girl, and from there his journey as a lord begins. Episode 1 is expected to depict this meeting and that very first step.
