Masachika Kumeno

Masachika Kumeno was a Demon Slayer closely acquainted with the current Wind Hashira Sanemi Shinazugawa.

Appearance
Masachika was a young man with an average build and short, spiky black hair. He had noticeably small, rounded eyebrows and two prominent scars on his left cheek. His mouth was usually curved into a happy smile.

Masachika wore the standard Demon Slayer uniform that consisted of a dark gakuran jacket, white belt, and baggy hakama pants tucked into white wraps of cloth around his ankles.

Personality
Not much is known about Masachika's personality, however, he was likely a very kind person, befriending Sanemi and even introducing him to someone that could help train him. In his will, Masachika considered Sanemi as a brother and wished the best for his loved ones.

History
Little is known about Masachika prior to joining the Demon Slayer Corps, but he had a younger brother killed by Demons.

After Sanemi began wandering in search of demons to kill, he met Masachika by chance. Masachika was already a member of the Demon Slayer Corps, and he arranged a trainer for Sanemi so he could properly learn how to defeat Demons. The two challenged and successfully defeated the previous Lower Rank 1 of the Twelve Kizuki, but Masachika perished in the conflict.

Sanemi rose to the position of Wind Hashira alone, bitter over his friend's death. When he confronts Kagaya Ubuyashiki about the latter's inability to fight, Kagaya apologizes for his weakness and identifies Masachika by name, much to Sanemi's surprise. Kanae Kocho then informs him that Kagaya has memorized every slain Demon Slayer's name and background, and Kagaya decides to give Sanemi Masachika's will.

Synopsis
Some years prior to the beginning of the story, Masachika encounters Sanemi by chance. They strike up an unlikely friendship, and Masachika even introduces Sanemi to a personal trainer so he could properly cultivate his skills. An unknown amount of time later, (but still several years prior to the beginning of the story) Masachika dies in battle against a past Lower Rank 1.

Sanemi Shinazugawa
Sanemi and Masachika had a close brotherly relationship, with Masachika viewing Sanemi as the younger brother he lost.

Abilities and Powers
Masachika was an incredibly powerful swordsman in his own right, as a tag-team effort between him and Sanemi was able to successfully defeat Lower Rank 1, the most powerful of the Lower Ranks despite sacrificing his life in the process.
