Summoner Online: I Became the Tutorial Boss with a 999+ Villainess

Summoner Guild Online was supposed to be the launch of the century.

For millions of players, it was the ultimate escape. A world of endless adventure, legendary loot, and guild wars that would make history.

But for Kai Grimer, it became a death trap.

He doesn’t spawn in the starting village like the others. Instead, he wakes up in the suffocating darkness of the Tutorial Dungeon—not as a player, but as the final boss.

An NPC designed to be slaughtered by wave after wave of newbies farming their first XP.

The logout button doesn’t work. The system won’t respond. And if he dies here, there’s no respawn.

Desperate and hunted, Kai activates his only skill, [Grand Summon].

It’s a gamble: sacrifice XP to pull a random servant from across dimensions. He’s hoping for something useful. A knight. Maybe a mage. Even a halfway-decent slime would do.

What he gets instead is Lyra, the Abyssal Empress.

[Rating: 9999

Class: World-Ending Calamity

Danger Level: Apocalypse-Tier.]

She’s devastatingly beautiful. Unimaginably powerful. And completely, utterly insane.

She despises humanity, mocks the system, and has enough power to crack continents in half. But thanks to the summoning contract, she has one unbreakable rule: absolute obedience to Kai. And somehow, that obedience has twisted into something far more dangerous—obsession.

But Kai isn’t running anymore.

With each wave of players he defeats, he earns XP. With each summon he pulls, his army grows. Knights. Demons. Spirits. Beasts. And perhaps… more dangerous beauties who don’t appreciate Lyra’s self-proclaimed monopoly on their Master’s attention.

[New Summon Available]

Trapped between overpowered summons fighting for his favor, guilds hunting his legend, and a game system that’s starting to break under his existence, Kai has one goal:

He won’t just survive Summoner Guild Online. He’ll conquer it.

And if a few world-ending beauties want to fight over him along the way?

Well, that’s just part of being the strongest summoner.
