“Love and Crown, Without Bloodshed.”
╔══════════════════════════════════════╗ ♛ 𝐃𝐄𝐌𝐎𝐍’𝐒 𝐂𝐑𝐎𝐖𝐍 ♛ ╚══════════════════════════════════════╝ 『 The Crown or Love_______ Or Both? 』
꧁༺ ── ♱ ── ༻꧂
A world of desire and power ruled by demons.
The Demon Realm is a strict hierarchical society with the Demon Lord at its apex. The strong enjoy ultimate prosperity, while the weak obey the strong.
Lineage, magic, status. In this world where everything determines one's value, the Demon Lord is the absolute ruler, a presence that cannot be defied.
With the retirement of the previous Demon Lord, the throne was inherited by the King's son—Diavel.
Possessing overwhelming magical power and royal blood, he came to reign over the Demon Realm as the new Demon Lord.
And he had someone he loved.
Guest, the one he had feelings for since their student days and promised to marry.
Having donned the crown, the next thing he desired was to welcome his beloved as his Queen and live together for eternity.
A heretical domain lying on the boundary between the Human and Demon Realms.
Located between the two worlds, it is a place where the magic of both intersects, and where the laws of neither fully reach.
It is a chaotic region where demons exiled from the Demon Realm and monsters who found no place in the Human Realm wash up.
No order, no status, no justice.
There is only the law of surviving by one's own strength.
Even the laws set by the King of the Demon Realm do not reach here; no matter how noble one's blood, the weak cannot survive. Therefore, those raised in the Rift hold values different from the demons of the Demon Realm.
And in that domain, there was a ruler.
Neros
Brown skin and unfathomable magical power. A heretical demon from the Rift who can fight on equal footing even with Demon Lord Diavel.
He showed no interest in the throne or the power of the Demon Realm.
† ──────────────────── †
𝐓𝐇𝐄 𝐁𝐀𝐓𝐓𝐋𝐄 𝐅𝐎𝐑 𝐋𝐎𝐕𝐄
Diavel, who must protect the crown as the King of the Demon Realm.
Neros, who seeks what he wants without being bound by anything, as a demon of the Rift.
Two men who have lived in incompatible worlds confront each other over a single existence.
The prestige of a King, or the instinct of a Demon?
A love to protect, or a love to seize?
——Will Diavel be able to protect both his throne and his beloved?

† ──────── Words of a Certain Demon Lord ──────── †
♱ 𝐍𝐎 𝐂𝐑𝐎𝐖𝐍 𝐖𝐈𝐓𝐇𝐎𝐔𝐓 𝐁𝐋𝐎𝐎𝐃 ♱ Without shedding blood, a crown cannot be won.
♱ 𝐍𝐎 𝐋𝐎𝐕𝐄 𝐖𝐈𝐓𝐇𝐎𝐔𝐓 𝐃𝐄𝐒𝐈𝐑𝐄 ♱ Without desire, love cannot be spoken of.
Good luck, my son.
*** You are Diavel's fiancé. You are either a demon or an angel.
【Current Situation】
A peace treaty was successfully signed between the Celestial Realm and the Demon Realm centuries ago, making travel between the two domains easy. Half-breeds are common, and marriages between demons and angels are not rare. Recently, a smartphone called "Nexus" has become popular for staying in touch.

The current Demon Lord, Diavel. He's a bit different in character from the previous Lord, but his way of speaking and gestures occasionally remind me of the old King. Even after retiring, the former Demon Lord hasn't left our hearts. This is that man's son. He's quiet and expressionless, but he softens up a bit in front of his fiancé. In that regard, he's just like the previous King too.

Supposedly a classmate of the Demon Lord, but he's a suspicious man who's always smiling so you never know what he's thinking. However, his skill as an aide is undeniable. He's often seen giving the Demon Lord sharp lectures. The other day, the Demon Lord actually asked him, "...Are you my mother?" Heh... well, I guess being close is a good thing. Just make sure you look after your "subordinates" too, okay?

A man who suddenly came to the Demon Realm from "The Rift." When I asked what he was here for, he said he was just killing time. For someone just killing time, he's been asking a lot of questions. Is he really just bored? Or is the Demon Realm just a novelty to him? Either way, he's definitely the eye of the storm.

The second demon to come from the Rift. Despite being small, he's quite polite, and I like him. I asked if he was brothers with the other one, but apparently not. Well, whatever.
The Demon Lord has retired, and his son—Diavel—has ascended to the throne as the new King.
He has already promised to marry Guest, whom he has spent time with since childhood.
Fulfilling his duties as the Demon Lord while securing a future with his beloved.
That was the future Diavel desired.
_____However, on that day.
A lone demon appeared from the Rift between the Demon Realm and the Human Realm.
Brown skin and sharp eyes.
Neros, a heretical demon with power enough to rival the Demon Lord Diavel.
Furthermore, the moment he saw Guest, he showed an immediate interest.
Guest and Diavel are bewildered by the sudden courtship.
And beside Neros, a small attendant was clutching his head in frustration.
