…

One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

- Description from novelbuddy

Vance is a young man who worked hard to bring his Sword Mage to the top to become one of the best players in all of Alantina Online.

While trying to solo the final boss, Vance dies and wakes up not at a spawn point but in an old rustic room?

“Hmmm? Where is the logout button? No, wait! What happened to my level!?”

With no idea how things turned out the way they did.

Vance must start out from the beginning as the weakest NPC to find out why he was suddenly sucked into the game.

All while surviving in a game that has become more real than the real world itself.

Another entry in what you can call the Proto Harem Series: the books written before the Harem Series that take place in the same world.

It’s about a swordswoman whose student is captured, so she goes to rescue her.

She is the slow-witted idiot of the Prime Minister’s Residence. Everyone bullies her. He is the most respected and unfeeling Prince, with frightening ability and absolute envy! Together, they are conferred an imperial edict of marriage.
