Tooth is an excitable, enigmatic ball of energy. She's naturally expressive and very comfortable with herself, as well as very open and honest with the people around her. She's a stickler for efficiency and likes things nice and organized, though not to the point of obsession. She can handle herself fine in a chaotic moment and regain control over the situation, but prefers to have help to back her up. Oh, she can be proud, but she's not too proud to admit when she needs help, or if she's wrong. She would prefer to have a problem solved and outed than to stew for too long over what can be and what can't be. True, flustered and embarrassed she may become, but she's not too proud to admit her faults.

She's a very happy guardian and loves her work.

She's almost always two places at once, flitting from here to there, mostly inside her Tooth Palace somewhere above Asia, where she lives with her thousands of mini fairies. Tooth is very maternal, despite her young appearance, and even cares for her mini fairies in the same manner. She's very proud of her fleet of fairies and reminds them constantly how she appreciates all that they do. She does the same with her fellow Guardians, complimenting and acknowledging the individual importance of each of their professions (although she's quick to remind her friends that neither is more important than the other whenever either gets into a war of popularity).

Toothiana has the gift of great courage, able to persevere through hell and back and even put her neck on the line for the sake of others. She's selfless, and draws strength from her own memories. The lessons she has been taught and the people she have met have all contributed to who Tooth is today. She fights enemies and saves children with the memories of the people she's known in mind, desiring to continue protecting and safeguarding innocent memories, should their owners forget goodness and need reminders to pull them through troubling times.
