Akari Murakami

Akari Murakami is a former resident Kagegakure who was forced to leave when her clan was massacred. Soon afterwards a guild of shinobi called the Koga Guild found her, took her in, and taught her the ways of a shinobi. Now she is revered within the guild for her complete mastery over a shinobi's skills and possesses strength far greater than what her rank may suggest.

Personality
As a very experienced shinobi, Akari has been on a lot of jobs such as espionage, sabotage, and assassination. This has caused her personality to develop an "adaptive" quality. This means that her personality, likes, dislikes, and tics fluidly changes depending on her environment and the people she is with. This trait allows Akari to gain anyone's trust or friendship and effortlessly infiltrate and community, no matter how tight the security of that community is. In addition, with her vast wisdom she can easily pick on body language of those around her to gain knowledge about the community she is in.

When Akari is around her close friends or the Koga Clan, Akari is often portrayed as a very lenient and easygoing person.

Memory Erasing Technique
Akari is able to use the Memory Erasing Technique through her Ketsugan instead of through physical contact. This technique allows her to erase all or portions of a targets memory just by looking them in the eye with her Ketsugan. To restore their memory all she has to do is tap their forehead.

Trivia

 * Akari's abilities were inspired by the traditional abilities and skills of real shinobi and the mythical abilities that are often associated with them.
