Ye Yunchuan transmigrated to The Devil is a Part-Timer! intending to play a game of wits, but unfortunately, he received the 'Many Children, Many Blessings' system.

Even more suddenly, the apocalypse arrived. Since a battle of wits was out of the question, he could only resort to a battle of... 'kun' (a euphemism for a certain type of battle).

Let's see how a master of 'kun' battles conquers the anime multiverse.

(Note: The protagonist is despicable, shameless, and a turn-off. Those who are righteous and upright, please do not enter.)
