The Emotion Manipulator: I Short the Gods Across All Worlds

To save my comatose younger sister, I activated the forbidden [Emotion Trading System].

From then on, rage became energy, utter sorrow became hard currency, and the joys and sorrows of all living beings became my stock chart.

Immortal-world bigwigs came knocking to collect debts, while the Abyssal Demon Lord wanted to short-sell my soul.

As for me, I calmly opened my account and laid my cards on the table before all the gods and buddhas in the heavens:

"Accept my emotional bonds, or... I'll make the emotions of the Myriad Worlds crash."
