Niko Mikadono is a high school student known for her long red hair, which she always ties in a ponytail, and her striking golden eyes. Despite her small stature of 150 cm, she possesses immense physical strength due to her rigorous karate training. As a powerful karate master, Niko carries herself with confidence and charisma, earning admiration for her toughness and determination. Her athletic build and disciplined presence reflect her years of dedication to martial arts, making her both respected and formidable among her peers.

Beneath her tough and commanding exterior, however, Niko has a softer and more reserved side. Though she is often seen as a tomboy, she secretly enjoys cute and feminine things, revealing a shy and gentle part of her personality that contrasts with her strong image. This balance between strength and sweetness defines Niko’s charm, making her a complex and endearing character.

Niko’s Sister

Kazuki Mikadono
Niko deeply loves her sister Kazuki and, having known her the longest, can easily sense when something is different in her demeanor. When Kazuki came down with a high fever, Niko wrestled her into bed and placed a cold compress on her, knowing how stubborn her sister could be. Despite their occasional clashes, Niko’s care and protectiveness show her deep affection for Kazuki. Thanks to Yuu’s influence, the two have grown even closer and now act more like true sisters, openly expressing their bond.

Miwa Mikadono Niko also shares a strong, if sometimes competitive, bond with her sister Miwa. As children, Niko often carried Miwa on her back, as Miwa loved getting piggyback rides. Now that they are teenagers, they tend to butt heads frequently but still care deeply for one another. Niko often gets annoyed when Miwa brags about having the bigger chest, yet their sibling banter only highlights their closeness. Despite their differences, the two even teamed up to follow Yuu and Kazuki on their date, showing that their playful rivalry doesn’t diminish their sisterly bond.
