Why Mob joins the Body Improvement Club
Mob’s psychic power makes physical weakness look like a problem he could ignore. His early connection to the Body Improvement Club reframes strength as a patient, social practice: something he can pursue beside other people, on ordinary terms.

Power does not answer the question Mob is asking
Mob can move objects and confront spirits with abilities that make ordinary physical effort seem almost beside the point. Yet his interest in improving his body is not a bid to become more formidable in the supernatural conflicts around him. He wants a kind of progress his psychic talent cannot supply. That distinction matters: strength, for Mob, is not simply the capacity to make something happen. It is the experience of working toward change with his own body.
The series makes the contrast quietly comic. A boy with extraordinary power is interested in a goal that demands repetition, time, and limited results. Psychic ability offers him a shortcut through many obstacles, but a shortcut would miss what he wants from exercise. His ambition suggests that he recognizes the difference between being capable and feeling capable. The Body Improvement Club gives that difference a place to matter without asking him to renounce what makes him exceptional.
Joining begins with uncertainty, not a triumph
Mob approaches the club without the physical confidence that its name might seem to require. The members are visibly stronger, and he is not suddenly transformed into their equal by deciding to join them. That gap could make the scene a conventional makeover setup, where an insecure boy is admitted only because a hidden talent is about to emerge. Instead, the initial appeal lies in the club’s willingness to let effort begin before it produces a visible payoff.
This is an important shift in what membership means. Mob does not have to arrive as an impressive recruit or explain his psychic ability to earn a place among the others. He can enter as a beginner. The ordinary awkwardness of that position gives his goal dignity: he is not pretending that the gap has vanished, but choosing to approach it. For a character so often treated as a source of overwhelming force, being inexperienced is a meaningful role to accept.
The club treats effort as something shared
The Body Improvement Club’s members make a strong impression through their physical presence, but the club’s appeal comes from more than their bodies. Their attitude toward Mob helps separate strength from intimidation. They do not reduce his current limitations to a reason he should stay away. By welcoming him into a collective routine, they make improvement a shared activity rather than a private test of whether he deserves to call himself strong.
That social setting changes the emotional stakes of exercise. Mob is not left alone to compare his reflection with an imagined ideal; he has other people beside him who understand training as ongoing work. Their encouragement does not erase the effort involved or guarantee a particular result. It makes the first effort possible. The club’s warmth therefore challenges a common story about strength as solitary self-mastery. In Mob’s case, company is part of what lets physical growth become thinkable.
A modest goal protects Mob’s right to choose
The club also offers Mob a form of agency that his psychic power can complicate. His abilities attract attention because they can solve dramatic problems, and people may look to him for what he can do. Physical improvement is different: it is a goal he chooses for himself, with no immediate crisis demanding it. That makes the decision feel personal even when he pursues it alongside others. He can care about a part of life that is not organized around being useful.
Mob’s early interest in the club does not promise that he will become a champion or that physical strength will settle every insecurity. Its value is more basic. It gives him a way to pursue ordinary growth without measuring himself by his extraordinary abilities. The club’s example suggests that strength can mean endurance, support, and willingness to begin while still weak. Mob’s most human aspiration is not to prove that he was powerful all along; it is to build something that power alone could never give him.
