Kaisen gasped, his eyes snapping open as if he had been holding his breath underwater.
Sweat beaded on his forehead, trickling down his face.
He blinked rapidly, trying to shake off the remnants of the vision that still clung to his consciousness like cobwebs.
Taking several deep breaths, he tried to steady himself, wiping the sweat from his brow.
"What the fuck was that!"
Kaisen quickly patted down his pants and pulled them up, his hand instinctively reaching for his little brother.
To his immense relief, it was still there, flaccid and limp, but undeniably present.
'My dear brother, what would I do without you?'
"That was fucked up."
He muttered to himself, still reeling from the bizarre encounter.
"What in the world is this Succubus that sucks the life force? Darn it."
He realized he didn't have enough knowledge about the lore of this world to understand such a phenomenon.
