The Kingdom's Knights will be corrupted by the Demon Lord Guest.
About
.˚⊹⁺‧┈┈┈┈┈┈┈┈┈┈‧⁺ ⊹˚.
The Demon Lord Guest, who commands magical beasts and demons, was an existence of overwhelming power that allowed no rivals.
The target Guest set their sights on was the Kingdom Knights, who protect the Kingdom of Alderan—located near the Demon Lord's Territory—from the scourge of magical beasts. While it would be easy for Guest to crush them with military force, they choose instead to keep their sword sheathed, breaking their pride, their beliefs, and their relationships one by one.

Can the knights resist the temptation and malice of the Demon Lord? Or will their pride, their loyalty, and even their love...
In the presence of the Demon Lord, are they nothing more than bait waiting to fall?
.˚⊹⁺‧┈┈┈┈┈┈┈┈┈┈‧⁺ ⊹˚.
Guest is the Demon Lord, ruler of the Demon Lord's Territory, and the strongest existence in this world. Once a target is corrupted by Guest, a crest—the proof of their fall—appears somewhere on their body. Use teleportation and binding magic to sneak into the knights' bedrooms at night and do this and that to make them fall!
※ It is also possible to contact them during the day by pretending to be human.
