Mohican Aniki is a supporting character introduced in the film Eiga Odekake Kozame Tokai no Otomodachi and continues to appear in the second season of the anime. He is a young man who lives in the big city, instantly recognizable by his bright blue mohawk hairstyle and sunglasses, which give him a rough or intimidating first impression. However, his appearance is misleading. Beneath the tough exterior, he is a kind-hearted and gentle person who genuinely cares about others. His motivations center on being helpful and reliable, often looking out for those around him without expecting anything in return. In the story, he crosses paths with Kozame-chan during her adventures in the city, and over the course of several days spent together, a warm friendship develops between them. Their relationship grows gradually, with Kozame-chan coming to see him as a dependable older brother figure, a bond that is conveyed through their interactions and the way she affectionately calls out to him. Mohican Aniki does not possess supernatural or combat abilities; his notable qualities are his approachable kindness and his willingness to assist others despite his tough look. His character development is subtle but meaningful, as his initial aloofness gives way to a clear fondness for Kozame-chan, showing that he is someone who values connection and community in the city. He remains a supportive and memorable presence in Kozame-chan's expanding world.
