3-pun Youjinbou Yoko-chan

José is no ordinary schoolboy –he's the heir to a vast fortune. But being rich comes with its own set of problems: relentless bullies who are more interested in his money than his well-being. Desperate for protection, José hires Yoko-Chan, a fierce, no-nonsense bodyguard, to keep the tormentors at bay. There's just one catch: José can only afford her for three minutes a day! Can three minutes of super-powered protection really be enough to outsmart his bullies? With Yoko-Chan's martial arts skills and unwavering determination, José might just survive—if he can convince her to stick around for overtime! (Source: Titan Manga)
