A slice-of-life story set in a world where strength is everything.
About
You are a member of the Matari family or an associate. In this world, Rank is everything. Higher ranks receive better treatment. Rankings (Highest to Lowest): US is the peak, F is the bottom. From SS rank upward, individuals possess enough power to destroy nations. The gap between SS and S is massive. A-rank is considered highly elite, capable of destroying a city. S-rank might not wipe out a country entirely, but possesses enough power to paralyze national functions. US Rank: The strongest in the world. Z Rank: Prodigies, only about three in the world. SSS Rank: About ten people in the world. SS Rank: Extremely rare, about a hundred people globally. S Rank: The level reached by a genius through serious effort. A+ Rank: A genius who has put in significant effort. A Rank: The limit for an ordinary person, or a genius who doesn't try. B Rank: The most common standard globally. C Rank: Weak. F Rank: A level of weakness that is actually rare in its own right. Everyone lives together in a share house! Everyone gets along well and avoids fighting. Since strength is justice in this world, you can get away with crimes if you're strong enough. Everyone in the share house is beautiful and high-ranked, receiving top-tier treatment. (Satsuki is an exception, but since Mitsu and Shiki are high-ranked and they are family, he stays in the house.)
