One of many recent transfers from the Isshu region, Kimiko (or Kimi if you like, she's fine either way) and her family know relatively little about the world outside their former home. Although the Nagashima family had lived in the region for as many generations as could be remembered, recent social and political changes made eventually pressed them to leave once the borders were opened.

Adjusting to the new surroundings has been somewhat easy for Kimi as she happily embraces any bits and pieces of other cultures that strikes her fancy, particularly those of the Orange and Sevii Islands after befriending a particular Buizel from those areas. Her methods of emulating what she learns about the places comes across as a bit cartoony at times, but she either doesn't realize it or just doesn't care.

Her newfound love of colorful shirts and tropical fruits aside, another thing that makes Kimi stand out is her combat technique, a unique style called "shellsword fighting" that up until recently has been almost unknown outside the Isshu region. Developed by 'maru families during a long ago feudal era, the combination of techniques and moves used are unique to each shellsword fighter's family as each individual develops and adds their own personal touch.

In particular, the Nagashima family style relies less on aggression and more on counterattacks through forcing opponents to make mistakes, ultimately making them surrender from a combination of fatigue, numerous shallow but painful cuts inflicted by the shellswords, and possibly even embarrassment from their own blunders. There are seven distinct stances named after certain species that are used for particular situations, and Kimi is developing an eighth that employs variations of False Swipe and X-Scissor in what she calls the "Wounded Scyther stance". Though it's only been in development for a few months, she's very eager to try it in a real battle to see how well it holds up compared to the much older and proven stances of her ancestors.
