勇者パーティーに属するヨハン・グリーシアは、SSSランクの固有スキル『建築士』をもつ冒険者。

Johan Greesia, a member of the Hero's party, is an adventurer with the SSS-rank unique skill "Architect."

彼は『魔王城の近くにギルドメンバーの拠点を立てる』『トラップハウスを建築し、多くの魔物を自滅させる』など、独自の方法で魔王討伐に貢献してきた。

He has contributed to the defeat of the Demon Lord in his own unique ways, such as "building bases for guild members near the Demon Lord's castle" and "constructing trap houses to cause many monsters to self-destruct."

しかし勇者が魔王を倒したその日に、役立たずの烙印を押されてパーティーを追放されてしまう。

However, on the very day the Hero defeated the Demon Lord, Johan was branded useless and expelled from the party.

さらに冒険者としての資格も失い、せっかくスキルで作った拠点も全て勇者たちに奪われる。

Furthermore, he lost his adventurer qualifications, and all the bases he had so carefully built with his skill were taken by the Heroes.

全てを失い、スキルで家を建てる気にもならず、一人で野宿をするヨハン。

Having lost everything and with no will to build a home using his skill, Johan camped alone outdoors.

そんな時、彼は同じく野宿をしている一人の幼女と遭遇する。

It was then that he encountered a young girl who was also camping outdoors.

「フェルキアのお城……。なくなっちゃったの……」

"Felicia's castle... it's gone..."

なんと彼女は、魔王の一人娘だった。

Astonishingly, she was the Demon Lord's only daughter.

勇者が魔王城に攻め入ったその日、魔王である父の命令によってたった一人で逃げて来たフェルキア。

On the day the Hero attacked the Demon Lord's castle, Felicia had fled alone on the orders of her father, the Demon Lord.

そんな身寄りを無くした彼女を他人事とは思えずに、ヨハンは一大決心をする。

Unable to view her, now without family, as someone else's problem, Johan made a momentous decision.

「任せて！　僕がフェルキアのために、世界一の魔王城を建築するよ！」

"Leave it to me! I'll build the greatest Demon Lord's castle in the world for Felicia!"

「うーーーーっ！（喜びの舞い）」

"Ooh! (A dance of joy)"

そしてヨハンは彼女のために、美しさも難易度も最高クラスの鬼畜魔王城を建築する。

And so, for her, Johan began constructing a brutal Demon Lord's castle, one of the highest class in both beauty and difficulty.

さらに、復活した魔王城に再び攻め入る勇者たちを『建築スキル』で撃退していく！

Moreover, he repels the Heroes who once again invade the resurrected Demon Lord's castle with his "Architect skill"!
