Marin Yukiame is a Hinoe ranked slayer of the Demon Slayer Corps, and a major supporting character of Kimetsu no Yaiba. She is also a user of Planet Breathing, and a member of the Yukiame Clan. After the war, she became the wife of Kaito Yuzora, one of the Kanoe ranked Slayers, who aided in battling Muzan.

## Personality

Marin is a very strict woman, who prioritizes the traditions of the Yukiame Clan, being loyal to her clan at utmost. She will not hesitate to push her fellow slayers to their limits, and will also work as hard as she can. She pushes her brother to the utmost limits, as well as herself. Despite this, she valued her brother's happiness, over the tradition and rules of her clan. She was also self-aware, and very observant. Despite her strictness, she has low self-esteem, and most especially, very low confidence. She also did not believe in herself that much, as she was even hesitant to acknowledge her own strength, saying that Seikuro was far superior to her in every way. She was very uninterested and acted quite calm, rarely showing emotion or rage and instead being cool-headed and calm.

However, when her talents are brought up, she becomes quite flustered and is empathetic with other's feelings, although she appears intimidating, indifferent, and aloof. She is also fond of certain people, such as Himari, the girls at the Butterfly Mansion, her brother Yukio, Hakua, Aoi, Mirai, Mitsuri, and even Saeko, as well as the members of the Yukiame Clan.

However, she does not speak that much with Seikuro, and has a fueling conflict with her and her abusive older sisters who always happen to pick on her. She is also very insecure about herself, especially her looks, as compared to her cousins and sisters, she does not possess a perfect body as them. This makes her want to look beautiful, and so, she ate less and less. She is also tough, uncompromising, and a no-nonsense woman, even more so than Aoi Kanzaki, but doesn't express how she feels clearly.

She did not want to be a demon slayer but was forced by the Yukiame Clan. She also felt no self-worth and was rather self-critical. She was also quite aimless, unsure of her true goal, and why she even lives. She also could become quite envious. She hated two faced backstabbers and was quite cynical of people, being unable to trust Nobara. She felt easily replaced, due to a female in the clan being very common. Despite loving someone that was not decided by her clan, she was trapped by the will of her family. In reality, Marin was only a slave to her clan's will and orders. Out of her fear from losing everything, she followed every rule without any hesitation. However, she sometimes showed care and affection for her friends, most notably Hisui Kaname.

Despite being born in the Yukiame Clan, she possesses an extreme amount sympathy and empathy for the demons that she kills, having no sadism in killing them. When a demon is severely weakened, she beheads them fastly, leading to a peaceful death. She was deeply saddened upon Ren Aoki's death, and was quick to conspire against Nezuko's beheading, upon seeing her innocence even shouting and yelling at Reika. Due to her abuse, she felt absolutely no worth, as she regularly received scars from the clan. She was also somehow straightforward, and sometimes intimidating to both enemies and her peers. She usually possesses no emotion, if you look at her face, but deep inside, she shows care and affection to others.

In the Sunrise Countdown Arc, Marin shows a merciless, violent, sadistic and brutal side, towards Muzan. She remains completely concentrated, and angered towards Muzan. However, she conveyed these feelings of rage and wrath on her attacks. She also expressed horror at the deaths of the Demon slayers, and vowed revenge against the Demon King, Muzan. She mercilessly sliced him, and was completely quiet and focused on taking him down. She is also rather verbally cruel towards him, expressing her hate in an open way, but with a raised voice.
