Isekai NTR Sensou

Reborn in a fantasy world as a humble butler serving a frail noble household, the modern era’s most formidable spy harbors two quiet convictions: a deep devotion to his gentle mistress and an unbreakable vow to defend her beloved homeland. However, peace shatters when the neighboring empire—commanded by stunningly powerful princess generals and backed by overwhelming military might—launches a devastating invasion. Confronted with an insurmountable disparity in armed forces, conventional warfare offers nothing but certain defeat. Refusing to let his mistress’s world fall, he discards the rules of honorable combat and reverts to his true nature as a ruthless operative. His strategy shifts from the battlefield to the shadows, aiming to infiltrate the enemy ranks and consume them from within. Armed with a unique skill known as Honey Trap, he sets out to systematically dismantle the invaders' unity. By seducing the opposing princess generals, he intends to sever their loyalties, break their hearts, and steal them away, proving that the ultimate weapon to protect the woman he loves is stealing the hearts of those who threaten her.
