Dressed as a Man, I Became Tycoon's Sweetheart - Chapter 7 - The Sister-Pampering Maniac

That night, she was dragged to the Bureau of Civil Affairs. Wait, after getting the marriage certificate, the husband ran away? And his identity can’t be found? OMG, did she marry a human or a ghost?

Disheveled, she entered the entertainment industry and almost got sexually assaulted by a director due to the unspoken rule. Young Master Moh suddenly reappeared, and that director was tortured before getting cancelled.

During a shoot, she almost died since her enemy wanted to destroy her. Then, hundreds of mysterious soldiers arrived and smashed everything. The producer was exposed of corruption and his life got destroyed.

She always fights back and takes revenge, not taking the high road.

What? A woman is after her man? No tolerance! She barged into that woman’s home and whooped her ass. She said afterward, “How dare you touch my man?”

Young Master Moh had to cover his forehead; he needed to teach her how to behave like a senior officer’s woman.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

You shall become king—

Ruling over all “serpents” in the world…

Become the man who bears the brunt of dragonkind’s fear and hatred.

A modern era when humanity is threatened by attacks from giant dragons flying from beyond the sky.

Controlling “leviathans”—serpentine spiritual beings created through magic—humanity is locked in a protracted war of resistance against the dragons.

Fortunately, there exist witches known as “magi”—battle maidens of salvation who formed covenants with “serpents” in order to combat dragons.

Nicknamed Hal, the young man called Haruga Haruomi makes his living through facilitating the covenants of these girls.

At the (partially coercive) request of his childhood friend Asya, one of Europe’s top witches, Hal returns to Tokyo New Town after an absence of three years.

Accompanied by the beautiful Asya whose appearance rivaled a fairy’s, Hal is running all over the place to secure his base of operations and taking care of matters related to school transfer when the elite dragon Soth suddenly attacks—!?

Life has been breathed into a brand new myth between dragons and dragonslayers.

A grand opening to the “birth” of a top-class battle epic!
