Does a Cat Second-Stringer Dream of the Nen Continent?

Kenma Kozume, the brains of Nekoma's volleyball team, comes down with a fever after a practice match and inexplicably gets bound to a System. [Dear Host, let's go explore another world! Mission objective: conquer the world!] "I refuse." [Huh? Monsters, rare beasts, treasure, artifacts, perilous lands, secret realms, mysterious magic radiating from a language called [Unknown], a mysterious otherworld! Don't you really want to go, Host?!] "...I guess I could." Sorry, but it's really hard to refuse a mysterious otherworld! It sounds super fun, okay! [Legend tells of a cat demon mage from beyond the world, wielding the power to destroy it. They control all things and have limitless abilities. Stay vigilant, for the cat's eyes are everywhere.] This warning has spread across the continent. Every hunter is wary of its subject, and every one of them has seen the legendary figure. The subject of those rumors, who can only visit the otherworld in his dreams, hates talking, has a System backing him up, and has a pair of catlike vertical pupils: "..." All I did was use your Nen and pull a little prank on you. Do you really have to be so stingy? He skillfully dodged yet another Blood Cult follower, ignoring the eyes trying to see whether he had ears. As he faced the Chimera Ant King before him, he skillfully used his ability. The next second, a black cat with an odd tuft of bangs dropped from the sky. Looking at Kenma Kozume, it spoke in a human voice: "Kenma, are you really a cat demon?!!" An unknown, mysterious otherworld, companions with wildly different personalities, incredible and powerful creatures... All of it was so much fun. The world was just a much bigger game, and he was its only player. Please Note: * The cat will have a huge golden finger and be strong in every way. Slice of life. * Mainly Hunter x Hunter.
