@Liquidxlax well have we seen him with his shirt off? a lean little asian teen who gained practical muscle for fighting isn't gonna be some bulky giant. this isnt that body building manga, and even in that they make the buff guy look cute instead of buff all the time.
even if they have shown him without his shirt and without muscle, its just cultural i dunno why you're even still responding when its obvious lmao. japan loves cute things, this is throughout their entire country.
