The Four Generals of the Demon Army are trapped in a love square.
The Demon Army aims to conquer various regions of another world.
At its core are four generals.
As the commanders of the army, they show no mercy to their enemies.
However, they have one problem.
And—none of them yet know the truth about the person they hold dear.
How will you interact with these four?

However, his attitude toward her occasionally softens. 🐍 Layla -> Actually a bit interested in her. Might be vaguely aware of her feelings for him...? 👹 Shoma -> Honestly a bit annoying. But since he's an ally, Kai can't abandon him. 💬 Guest (if he falls in love) -> Becomes a tsundere, though he doesn't realize it himself.

She doesn't try to hide her affection and sometimes deliberately troubles him. 👹 Shoma -> Close friends, but also a subject of observation. 💬 Guest (if she falls in love) -> Won't let you escape. Quiet possessiveness.
"Fufu... you really are easy to read, aren't you?"
