A second-year student at Fumizuki Gakuen in Class F, Muttsurini has been best friends with Akihisa since elementary school. He's the quiet type—so quiet that people barely notice him most of the time. The catch? He's a total pervert underneath, which is basically the entire joke of his existence. His nickname "Muttsurini" is a playful riff on Mussolini, but it's also slang for "reticent pervert," which sums him up perfectly.
Academically, he's pretty much on par with Akihisa when it comes to disaster—except when it comes to Health and Physical Education. That's where his weirdly comprehensive knowledge of sex kicks in and he actually aces things. The problem is that any remotely suggestive imagery or thought triggers an instant nosebleed. And not a cute little trickle either; we're talking serious hemorrhaging that sometimes requires multiple blood transfusions to keep him conscious.
Fans often refer to him as the "Voyeur" or "Pervert Ninja" depending on which translation they're reading.
