Fortunately, that is exactly what Nobunaga took it to mean. That Klaus trusts him, and wants to direct himself for as much chaos as willed, not that Klaus wants to be a pacifist, nor necessarily prove he can fight alone, which he already knows, but doesn't want to.

"Good. Then let's entangle them further so no one can separate them, like having sex." Nobunaga gives Klaus a hard tug, and an even harder kiss. Ah yes, Klaus' stupid Demon King husband who thinks holding hands is more intimate than sex.

Unfortunately he knows exactly what he would do without Klaus, and he hates it. Klaus makes everything better. Like candy.
