Moto Sekai Ichi'i no Sub-chara Ikusei Nikki - Chapter 2: Sub-Character

In the world of One Punch Man, the seventh S-class hero of the Hero Association, the King Engine King has obtained the super god skill system.

As long as you have reputation, you can extract the skills of the heavens and the world!

DNF’s extreme swordsmanship, the flames of fire in the god of death, the Tensei and Samsara in Hokage, the top three-color domineering in Pirates, the dragon slaying magic in Fairy Tail… Look at the system panel. For the 100 million prestige balance, KING took a discount and chose Stud. “Ding!”

When she reborn, she finally understood; men can never be relied on.
That being the case, she can only rely on herself to win, that
splendid brilliance she yearned for, in this lifetime.

To my scheming Stepmother and ruthless sister, I will
destroy all your backings, pull off your wings, and step on your
arrogance! As for Grandmother whom speaks kindly but has a snake-like heart,
and a father who is hypocritical and exploits advantages; I will tear
off your pretense and cut off your hope! Let’s see how you can still
scheme against me!

Witness her splendid fight against her stepmother, punish scum men,
and create havoc in the imperial court, as she soars with the wind and
rises above the water!

But as for that man who still stands! How dare he play with my heart?
