Vampire Hunter: Blood Rights, a highly acclaimed Virtual Reality Roleplaying Game. Lucian Silver was a normal guy who worked months to afford this game.

He raced home the day his VR unit arrived with the game. His enthusiasm was so great he spent 12 hours to make his character look similar to the NPC with the same name as him.

His choice would change his life forever!

Lucian Von Silver was a baron who had a fiancé in the game that would devolve into one of the early villains because of his jealous and how the protagonist would approach his fiancé Carmilla. This friction would eventually escalate until he died at the hands of Lance. Carmilla also died trying to block the sword aimed at his heart, showing her true feelings that were hidden all these years.

The moment Lucian created his character, lightning struck his apartment first, frying his computer. He thought to salvage his computer only for the second bolt to arc and strike him. Lucian died instantly.

Lucian awoke to find himself inside a strange mansion inside a casket. He has switched bodies with the former NPC Lucian Von Silver the baron. His blood boiled, although he was given a second shot at life. He was stuck inside a useless playboy who had nothing but his body as capital.

His fiancé was the beautiful woman named Carmilla. She struggled to show her emotions properly, which led to the strangely dense playboy and her to miss each other’s affection for each other.

Lucian felt despair. He wasn’t smart enough to survive with ease. Neither was he a martial artist with hidden powers. Just an unfortunate boy who failed to protect his sister and became a shut in.

A system appeared to save him from death.

[The Seduction System]

This system would help him grow out of his otaku personality. He’d gain a currency called Seduction Power [SP]. With this currency, he could buy various items, power-ups and bloodlines. But to gain this, he needed to seduce, molest, and have sex with women. He felt uplifted with a system aiding him. But he was a virgin with no female experience. What did he know about seduction? Could he really use this system?

Let us follow Lucian on his dark and thrilling erotic adventures. Will he kill the [Hero] Lance, or just flirt with his fiancée after discovering her deep affection?

But... Would the dark tides of fate and destiny allow him to be so relaxed simply by seducing women?

There was a mysterious old man who approached the failed swordsman with the “100 million years button”. A magic button which can achieve the same effect as training for 100 million years if you push it.

The failed swordsman who pushed the button had his doubts, but immediately felt tremendous power rising in his body. So he pushed the button many times.

However it was a cursed button. The moment it was pushed, he was confined to the 100 million years prison of time. The first 100 years were devoted solely to training. After 1000 years he had forgotten why he swung his sword. He stopped thinking completely after 10,000 years had passed. After 100 million years he became crippled and finally managed to return to the real world. At the same time losing all his memories from the past 100 million years, the only thing that remained were his sword techniques. “I can become stronger just by pressing the button!” or so he thought and pushed the button many times after that. Foolishly trapping himself in that 100 million years of hell each time.

As he continued this loop, he began to think “If I destroy this world, will I get out of here?” A few billion years later, he finally escaped from the loop.

This is the story of a failed swordsman trying to make a name for himself in the world.
