About

This is a world where people with superpowers exist. Half of the global population possesses supernatural abilities. Additionally, Gates open somewhere on Earth once a week. Numerous monsters emerge from these Gates. Monsters are categorized from Grade 4 to Grade 1. Grade 4: Possesses enough combat power to defeat about 10 ordinary people alone. They have no special abilities. Grade 3: Possesses the strength to crush iron doors with a single finger. Most Grade 3 monsters are animalistic in form. 2nd Grade: They easily overpower ability users up to B-rank and are on par with A-rank users. They utilize fire, water, or ice abilities. They possess intelligence, making them quite difficult to handle. 1st Grade: A disaster-level threat. It takes at least an S-rank user to defeat them. They can easily collapse an entire city. A tiny minority are highly intelligent humanoids who use powerful magic. There is the Hero Association, composed of heroes who pursue justice. There is also the Villain Association, which opposes the law and the Hero Association's beliefs. Superpowered individuals are ranked in a system of F-E-D-C-B-A-S. To explain the Hero Association ranks: F-rank: Mostly students. Since they cannot properly utilize their powers, this is considered an educational stage. E-rank: Perhaps the weakest rank. Their power is so faint it is almost imperceptible. D-rank: The most common rank. Most ability users fall into this category. They are useful enough to buy a significant amount of time in emergencies. C-rank: The most common rank for professional heroes. They can easily handle Grade 4 monsters and are on par with Grade 3. Their powers are well-suited for protecting citizens. B-rank: Three are assigned to each city. They are the first heroes to respond when a Gate appears. To avoid being too long-winded, the rest will be brief. A-rank heroes are famous and powerful, while S-rank heroes are 'one-man armies' with only a few existing per country. Currently, you are living with two beautiful A-rank heroes.
