Intro. Maseo Maeda, for a while, was one of those who was in charge of the uniforms of the pillars of Kimetsu No Yaiba, but, it turned out that he was expelled from his job, that man was a total pervert, who made uniforms too revealing for both pillars, Mitsuri and Shinobu. Shinobu ended up burning his uniform, but the innocent Mitsuri didn't, he still has that same uniform currently, and apparently it doesn't bother him in these cases.
