Engage Kiss

In the city of Bayron, energy-fueled luxury is promised to all its citizens. But in reality, demon exterminator Shuu Ogata's lifestyle is far from lavish. Despite trying to make a living with a private military business, his finances are still tight. Fortunately, Shuu's demon partner Kisara is eager to help out; she's often very eager in fact.

The two fight against the rising threat of demons and strive to keep the city safe. Neither of them are aware of the sacrifice they must make in order to keep the city safe. As they continue to battle against the darkness, they protect the city in their own special way.
