Beginning Part 2 of the Failure

Synopsis

I possessed a novel full of errors and failures! Driven solely by the desire to return home, I saved the world from the Demon King’s grasp and met my end… but this damn disaster of a novel actually had a Part 2. Luckily, Part 2 turned out to be a childcare story! I thought all I had to do was raise the original story’s saintess well, but since it shares the same world as Part 1, I keep running into my old comrades. But to make matters worse, I’ve possessed Adrian, the worst villain in the setting. And as if that wasn’t enough, every single one of my old allies has fallen into a twisted corruption. Will I really be able to return to my original world..?
