The supporting character's harem is very normal - Chapter 299 You mean... Charlotte?

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

“Your Majesty, please break-off my marriage with Her Highness the Imperial Princess. I fell in love with Lady Adriane Reese.”

“Six engagements, Six break-ups.”

The princess’s fiancé always had an affair with the maids!

“I don’t want to marry the crown prince, I want to live with my father forever…”

“Such a useless being. Begone!”

The princess who is known to be weak and s*upid, Apollonia.

But she has another hidden face…

“It’s because the throne is hard to obtain, my father also spent 10 years on trying to kill my mother, the empress.”

As Apollonia grinned, her red eyes shone intensely. Usurpation of the throne.

Her goal was clear. She was never shaken.

‘I want to live my life with my father.’

To be exact, I want to live my life where my father is seated.

Please wait, father. Your daughter is on her way.

But one day, he stumbled upon something that would change everything: dungeon streaming. And from that moment, his world would never be the same.

I opened my eyes to find myself in another world. For some odd reason, I ended up as a sword. Before my eyes laid a plain full of magic beasts, and so, I launched my body and flew in search of a partner, a wielder (females only).
