Synopsis

About Haven't You Heard? I'm Sakamoto

Model student, beacon of inspiration, gentle spirit of guidance, and friend among friends — you name it, Sakamoto can do it. He’s your go-to guy for any problem. But not everyone takes kindly to his unflappable persona, because, let’s face it, no one can truly be his match. Right? In the face of bullies, braggarts, and killer bees, Sakamoto always keeps his cool. You haven’t heard of Sakamoto yet? Don’t worry, you will.
