Machio Naruzo

Machio Naruzo (街雄 鳴造, Machio Naruzō; "Naruzo Machio") is a bodybuilder and personal trainer at Silverman Gym who regularly coaches the main characters from Koyo Women's Academy.

Appearance
Machio is a tall man of fair complexion. He has messy short black hair, blue eyes, and a very handsome profile. He is most commonly seen wearing a blue and white tracksuit. Although he normally appears to be a slender of average frame, he is in fact very muscular. Once flexing, he reveals such a deceptively large and well-defined physique, which is a complete contrast to his babyface, that he literally rips apart his clothing as he bulges out until all he is left wearing is a speedo.

Personality
Machio is by nature a very kind a helpful man who is dedicated to help the members of the Silverman Gym better themselves. When Hibiki asked him if he would laugh at her after she is barely able to complete three sets of bench presses, he answers that he cannot laugh at someone trying their best. He is noted to have a charming personality and he is very knowledgeable about bodybuilding and exercise.

Machio's running gag involves him doing a bodybuilder pose where he bursts out of his clothing to reveal his well-built body. So fixated on physical fitness and his own physique, he looks for almost any excuse to show off, as even words that remind him of his muscles compel him to flex. He appears to be oblivious to how much his body freaks people out and apparently no shame about being almost naked in public.

History
Little is known about Machio's past, but, it is known that he has been incredibly buff since high school, due to being a member of the football team. He went to the U.S to study sports theory and studied under Barnold Shortsinator.

Plot
Machio appears when Hibiki tries to leave the Silverman Gym due to the too many macho men training there. She immediately changes her mind when seeing him and develops a crush on him because of his good looks.

Physical Abilities
As his physique would imply, his strength is leagues above the average human. He is able to effortlessly tear through his clothes simply by flexing. He is also able to chose whether a piece of his body or his whole body flexes to tear through his clothes. He crushed an iron grip with a single grasp.

By his own account, he was strong enough to bench 100kgs when he was just starting out.
