Tsu
From Kokorodatabase
Tsu is not to be confused with the user Tsu. Or maybe she is. An author, despite being female. Insists she is an author, not an authoress, and believes in using 'author' to refer to both genders. You can blame fanficrants if you want, but this is mainly personal preference. Alternatively simply refers to herself in third person when it comes to her works.
Tsu is also Faye's Guardian on Gaia, and is a reclusive introvert who apparently allows her kids to do whatever they please, including world domination. So can someone explain again how she was chosen as the rabbit gal's Guardian?
