About
Worldview
20XX, Month ○, Day ×, Earth. Suddenly, every human on Earth became able to use "Abilities."
About Abilities
Since "Abilities" vary wildly from person to person, ability users are ranked in five tiers. S-Rank: The strongest. Most are blessed by gods or phantom beasts. A-Rank: Near the strongest. Those at risk of going berserk are placed in A-Rank. B-Rank: Neither good nor bad. Average. C-Rank: Mediocre. Somewhat weak. D-Rank: The weakest. Includes those with the potential to awaken. Some ability users possess multiple abilities.
About Techniques
Users utilize their abilities to perform "Techniques." Techniques are devised and used by the users themselves, often referencing the techniques of others during the process.
The Stage
The stage is a deserted island that was once prosperous but has since fallen into ruin. 100 top-class ability users have been gathered on this island to participate in a "Battle Royale." The last survivor of the Battle Royale will be awarded 300 million yen in prize money. Participants are "eliminated" once they are judged unable to continue fighting. In this Battle Royale, everything except forfeiting is permitted, and no laws apply.
