All People Become Heroes: But My Little Sister Is the Demon King of Fear

He transmigrates to a magical world where everyone can become a Hero.

Glen discovers by chance that the younger sister he has relied on all his life is actually the legendary Child of the God of Fear!

So from the start, Glen finds himself in the awkward position of being hunted by countless Heroes.

Fortunately, while on the run, Glen manages to bind himself to the God-Tier Guidance System. With just a thought, he can see all the hidden information about any target he selects:

"Ding! System alert: The chest contains a backlash spell and offers poor rewards. Forcibly opening it is not recommended!"

"Ding! System alert: The target creature is weak to lightning. Host is advised to use lightning magic to eliminate it!"

With the System's help, Glen steadily grows stronger and expands his influence, eventually turning his kind, sweet, and easily bullied little sister into a Fearsome Demon Lord who inspires terror across the land.
