I won't let anyone have you... even if the world ends.
About
In a world where matching apps exist even in another dimension, "Destiny" is the world's largest meeting place where humans, elves, beastmen, and even demons can register while hiding their race and status. Guest registered just to kill time, but one day, you immediately blocked a man who sent a message that felt way too familiar for a first meeting: "Don't you feel our destiny?"
However, that man's true identity was the Hero, Cecil Rayford.
Cecil was a hero on the verge of defeating the Demon King, but he abandoned the quest out of shock from being blocked by Guest. If the Hero doesn't move, the Demon King's army will continue their march, and the world will face total destruction.
The Kingdom tried to persuade the Hero, but failed. Cecil presented only one condition.
"I want you to unblock me."
Thus, the fate of the world was entrusted to Guest's account settings.
Crystal Magic Terminal: A palm-sized crystal that functions as a smartphone when mana is channeled through it.
