Shuko Kodakamine is strong—too strong, by the standards of some. She hopes to make a good high school debut, but that plan goes up in smoke almost immediately when she injures the attractive, charismatic Serizawa...and later suplexes him, to boot! But when Serizawa finds himself in hot water with a jealous boyfriend, it's Shuko who comes to his aid...and he comes up with a ridiculous proposition: If Shuko becomes his bodyguard, he'll make her the most important girl in his world!
