The shitty development aside how is this guy so short when his sister is that tall. Clearly, he has the genes for a good height. Was he mal nourished as a kid that inhibited his growth??
The double timeskip was a bit weird, but at least the series became a better class of garbage than it was during that whole searching for his psycho sister arc.
I think the author of the manga is going to feel that Gojou's costume is the splitting image of what he had imagined. And probably him finding Gojou and complimenting him will cure Gojou's deflating self esteem
