Masao Maeda

Masao is a young man of ordinary height. Because every Kakushi member covers their head and wears a mask, most of his features stay hidden from view. What can be seen are his green eyes, thick rounded brows, and the wide circular spectacles he relies on to see clearly.

Masao is widely disliked across the Demon Slayer Corps for his lecherous conduct, which has earned him a contemptuous nickname. He designs sexualized garments for female slayers and pesters them about it. When confronted, he deflects and gaslights, even falsely claiming that the kind master Kagaya Ubuyashiki signed off on the outfits.

He grows visibly panicked under pressure and tries to talk his way out of trouble, especially terrified at any chance that Sanemi Shinazugawa might appear, stemming from an earlier scolding that left him soiling himself. When Shinobu burned the uniform he had crafted for her, he flung himself to the ground in apology while wailing over the loss of his work.

Despite abusing his role, Masao is a genuinely competent seamster. The uniforms he produces are noted to resist the attacks of weaker demons, repel water, and avoid catching fire, which shows he understands how to build rugged, practical clothing for combat use.
