Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

“Can you be useful to me?”

“I… I can be…”

The first time they met, she knelt trembling before him, begging for shelter. The slave caught his interest, and he brought her back to his palace.

She could’ve never imagined that in one night she’d go from a spoiled little slave princess of a defeated kingdom, to becoming a powerful prince’s pet.

He kept her by his side… spoiled her, cared for her, loved her, and gave her meticulous care and high status. Whatever she wished… she could do so under his name.

But, she angered him and chose to run away. He captured her within a day.

“Don’t forget, my little dearest, everything I have given you can be taken back…”

In a spur of anger, she hit him, her feeble hands striking against the flesh of his cheek. Gnashing her teeth in anger, she said, “Do you have the ability to take my child back?!”
