Respawned as the Tutorial NPC (But I Have the Admin Panel?!) [LitRPG and Isekai/Reincarnation]

Kenji Arata was supposed to say one line. That’s it. “Welcome to the Kingdom.” After a completely avoidable argument with a truck, he wakes up reincarnated—not as a hero, not as a villain, not even as a background adventurer— —but as the tutorial NPC standing at the front gate. Locked in place. Scripted dialogue. Zero freedom. Until the system glitches. Suddenly, Kenji gains access to something he absolutely should not have: An Admin Panel. He can slightly adjust dialogue.Spawn minor items.Influence quests. Very slightly. Very illegally. When a group of players—led by a suspiciously lucky “main character candidate”—begin taking his secret hints seriously, Kenji accidentally creates hidden quests, unstable boss fights, and narrative chaos that shouldn’t exist. The more he bends the story… …the more something else starts watching. Because Kenji wasn’t meant to be summoned into this world. Someone else was. And the system is slowly trying to correct its mistake. Now trapped between players, fate, and a divine server that doesn’t recognize him as either NPC or player, Kenji must carefully scale his authority—without crashing reality itself. After all… He was only supposed to welcome people to the kingdom.
