Japanese VTuber Amakusa Miro, renowned for her unique style of playing video games exclusively with her feet, recently showcased an unusual muscle development on her left foot to her followers. She humorously dubbed this phenomenon the “Amakasu muscle” and playfully suggested that companies might consider advertising on her distinctive feet.
Miro explained that this distinct muscle formation is not an anomaly but rather a result of the constant, intense strain placed on her foot during gameplay. She first noticed it while reviewing one of her past live streams. The VTuber elaborated that she keeps her left foot elevated and uses it for character movement—specifically, controlling the left stick and the D-pad. In contrast, her right foot typically rests on the controller, managing action buttons and camera controls.
This specific distribution of physical effort has evidently provided a rigorous “workout” for her left foot, leading to the noticeable enlargement of this particular muscle. Such a unique adaptation highlights the extraordinary dedication involved in her gaming approach.
Miro specializes in competitive multiplayer games, demonstrating impressive skill in titles like Splatoon 2, Monster Hunter Wilds, and Mario Kart World. She has achieved significant milestones, such as reaching the maximum rank in Splatoon 2 and solo-defeating a high-level monster, Arkliv, in Monster Hunter Wilds in under three minutes.
Taking her unique physical trait in stride, Miro joked that she might have developed muscles that are absent in other individuals. Her lighthearted suggestion about ad placements on her feet further underscores her amusing perspective on this distinctive aspect of her gaming career, blending humor with her remarkable talent.
