Editing Dark Esquire (section)

===Energy Exchange Kiss (★☆☆)===
By kissing, the dark knight and the dark esquire can exchange energy with each other, replenishing it. It is said that a dark esquire who has mastered the skill of mana exchange can exchange energy through kissing as effectively as during sex.<br/>

The mana transmitted directly through the mouth contains much of her husband's essence and enhances the dark knight. As a result, this husband's mana restores a large amount of her wasted energy and dramatically activates her body, increasing the power of the techniques used. In addition, when kissing, the exchange of mana is ensured by the intertwining of tongues, which thus transmits a denser magical force, which enhances the effect of the kiss. Also, the effect of the kiss increases in proportion to its duration.<br/>

As you can see, for all monsters with the nature of Inma, a kiss from a husband is like "feeding" and they are encouraged to "feed" in this way regularly during battle. dark esquires kiss their loved ones even when they are on the battlefield so that their knight spouses are always in perfect condition. This is why it is not unusual to meet a dark knight and a Esquire kissing again and again in the middle of battle. It is a proper and wholesome action. They don't do it without intent, just because they want to kiss. Probably.
