Demon Queen Rebirth: I Reincarnated as a Living Armor?! - Chapter 739 - I Only Trust Your Judgement A Bit!

Tsunderes are refreshing at times but having to chase a wife is hell. Oppress the tsunderes!

In ancient times, oppressive scums were boring old stories. It was pure crap, only for entertainment, having neither escalated or was serious plot. Everyone just enjoyed reading it.

“Your servant is Majestic Star ‘Panther Head’ Lin Chong, from this day forward I am your woman!”

High school student Mikoshiba Ryouma was summoned to a different world in the middle of a war. Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape. After the escape, he rescues two twin sisters from the hands of thieves. The sisters who can use magic, swear to serve him as subordinates. Thus, Ryouma begins his journey on the path of the supreme ruler.

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.
