- Description from Novelupdates

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)
