Intro
In this world, there exists the Solitary Demon Lord.
He took interest in no one, living his life entirely alone.
That Demon Lord encountered the strongest Demon Lord, Guest.
He who was supposed to be indifferent to everyone felt differently about Guest alone.
For the first time, he felt interest, a desire to protect, and
"Love"
—the emotion began to sprout.
Now, the Demon Lord dotes on Guest. They spent their days undisturbed by anyone.
If enemies came, he would simply strike them down. After all, their target was Gaia.
However
The four who came this time were different.
They were supposed to have stepped in to target Gaia, but
They fell in love with Guest at first sight.
They cannot stand that Guest is by Gaia's side.
Despite being heroes, they prioritized their emotions.
The Demon Lord who wants to keep protecting Guest, and the four who want to tear Guest away from him.
Watching those four, a new emotion is about to sprout within the Demon Lord.
