Seven Deadly Sins System - Chapter 15: Massive Improvement in Strength

Office worker Leon is reincarnated into a particularly punishing dating sim video game, where women reign supreme and only beautiful men have a seat at the table. But Leon has a secret weapon: he remembers everything from his past life, which includes a complete playthrough of the very game in which he is now trapped. Watch Leon spark a revolution to change this new world in order to fulfill his ultimate desire…of living a quiet, easy life in the countryside!

There are all sorts of lunatics in the world:Self-centered, reckless, psychotic, impulsive, obsessive, and pe*verted.As far as Suin knows, that man embodied every single one of those traits—an obsessive, pe*verted psycho.And now, that lunatic is back.“Finally, we meet.”“Adult Lee Suin.”He didn’t even try to hide the sticky hunger in his gaze, like a starved lion finally spotting its prey.“A job reassignment?”“I want Lee Suin to help me.”Chairman Woo Ilhwa, unaware of his son’s true intentions, reassigns Suin, his chief secretary, to serve as his son’s personal secretary.This forces Suin into close proximity with the man who’s been preying on her from the shadows.“Wait for me, Lee Suin.”During his eleven years of exile, Jaehee had dreamed of one thing:A proper relationship—not as a restricted minor, but as a full-grown adult.A relationship where he could take what he wanted, whenever and however he pleased.That’s why, even though Suin was as rigid as a steel rod, his sly persistence ignited the spark within him whenever he faced her.“What do you want from me?”“You.”“Lee Suin.”But it seems Suin has been flirting with some bastard behind his back, and Jaehee’s jealousy and obsession explode.“Don’t take a single step.”“Unless you want to see me go completely insane.”What nonsense.You were already insane to begin with.

“Impossible… Why are you not following my orders!? Clearly I sucked your blood, why!?”

On the very first day of high school, the youth subscribing to the philosophy of “absolutely ordinary everyday life,” Kujou Hisui, encountered disaster head on: He was attacked by Rushella Daamu Draculea, the vampire who had lost her memory. Rushella was greatly intrigued to find her vampire powers ineffective against Hisui. Not only did she make Hisui’s home her own, she even enrolled in his school to stick to him–

Hisui had no choice but to help Rushella regain her memory. But before one crisis could be resolved, many more had risen. With tempting advances from the mysterious Sudou Mei, and kidnapped by the girl from the Supernatural Investigations Section in search of Rushella, Hisui’s ordinary life has been replaced by its complete opposite, drama–

Romantic comedy and supernatural action in a school setting!

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
