Aaron L. Goosby/Yon

Yon is a Thought Projection and one of the Seven Concubines (Romaji: Shichisokushitsu, Kanji: 七側室).

She is representative of Aaron's happiness and deception and as a result she serves as his spokeswoman whenever he is in such a mood.

Personality
Contrary to popular belief, the Seven Concubines aren't just manifestations of Aaron's personality. They're also individuals in their own right and as a result of such each of them have a personality of their own.

Whenever she isn't serving as Aaron's spokeswoman, Yon prefers to just kick back and relax. She'll take lengthy naps or indulge in a book of her liking.

Much like Aaron, Yon is an introvert. Meaning she prefers to be alone rather than with others. As a result, she doesn't take kindly to interruptions. And is willing to resort to violence in order to deter others from doing so.

Aaron L. Goosby
Yon thinks of Aaron as her personal pillow. At times, Aaron is amused. Most of the time he isn't though.

Wŭ Xíng Magic
Much like Aaron, Yon is a practitioner of Wŭ Xíng Magic (Romaji: Gogyou no Mahou, Kanji: 五行の魔法). Wŭ Xíng Magic consists of casting Combination Spells that are composed of Wood Magic, Fire Magic, Earth Magic, Metal Magic, and or Water Magic. In particular, Yon specializes in Wood Magic.

Wood Magic
Wood Magic (Romaji: Moku no Mahou, Kanji: 木の魔法) is Yon's area of expertise. Under normal circumstances, Yon utilizes to generate bizarre-looking trees that'll do most, if not all, of the work for her. Only when necessary does she actually manipulates the wood herself.
