Ethan wakes up expecting to see the walls of a hospital room—only to find a system message blinking in front of him:
[Ding! You have killed a green worm]
[Ding! Green worm has been added to your summoning list]

Anything he kills becomes his to command?!

Ethan finds himself in a brand new world filled with magic and power. Awakened with an SSS-ranked class, he rises to power by conquering everything that stands in his path. While other summoners struggle with their dozens, he gathers millions as his army. There is no limit to how much he can grow, but he quickly realizes that forbidden power doesn't come without consequences.

Limitless Summoner: Rise of the Soul God

Ethan placed a firm hand on Luna's small shoulder and looked her straight in the eye. "Alright, Luna. If this is what you want, I'll help you."

Luna's face brightened, but Ethan raised a finger before she could get too excited. "But this isn't something we can rush. I need to figure out the right way to do this. If I mess up, it could hurt you."

She nodded vigorously. "I trust you, big brother!"

Ethan inhaled deeply. Just as he was wondering what to do now and how to proceed, a system prompt flashed before him.

[Ding! Do you wish to contract Xerthamia Thalia as your summon?]

Ethan's eyes widened slightly. Was this her real name? It sounded like a disease more than a name. Should he tell her? He decided to save it for later.

"Yes." Ethan mentally willed, wondering what else was going to be revealed.
