Comment by Adrien on +99 Reinforced Wooden Stick - Chapter 46

So what I'm understanding is that Luna will die since she's the Lu**, one of the Deadly Sin. So she made the MC genderbend so that he could somehow take her place instead and become the Sin of Lu**. It's a pretty roundabout solution, but i suppose it makes sense.
(Imagine if I'm completely wrong and am spouting some random BS 💀)
