Ozaki VS Kozo Kanamori

Ozaki
Ozaki (尾お崎ざき Ozaki?) was a Demon Slayer and part of the Demon Slayer Corps. Ozaki was a petite young girl with wide, dark brown eyes that faded to a lighter color at the bottom and shoulder-length black hair that she wore tied up in a mid ponytail, with some sparce, shorter bangs left hanging over her face. Not much is known about her personality, but it's seen that she was a very considerate, selfless girl when she warned her fellow Demon Slayers to not approach her since she'd just end up unintentionally hurting them. As a low-ranking Demon Slayer, it's assumed that Ozaki possessed the capability to swiftly deal with the weaker Demons.

Kozo Kanamori
Kozo Kanamori (鉄か穴な森もり鋼こう蔵ぞう Kanamori Kōzō?) is a swordsmith affiliated with the Demon Slayer Corps. Kozo is a man of average height and build with chin-length black hair that spikes near the ends. His hands are covered in visible blisters and he wears a Hyottoko mask over his face. Kozo is usually seen wearing a long, pale robe with a black haori. Kozo appears as a gentle, soft-spoken individual. He is capable of understanding the hot-blooded Hotaru Haganezuka and cares for others very much as seen when he continues to protect Hotaru against an attack from Upper Rank 5, Gyokko, despite being critically injured.[2] However, when it comes to his swords, Kozo is very passionate. When Inosuke Hashibira purposefully chips the dual blades he received from him, the swordsmith is furious and berates him.
