Tifana

Tifana, better known as Ti (ティー), is one of two companions of Shizu during his travels. Riku serves as her guardian.

Ti first introduced to Shizu in the Ship Country by an elder as his guide. She is about twelve years of age, or at least, around the same height of a girl at that age. Her hair is short and white, unlike the remainder of the citizens in the country, who have black and brown hair. She also has an eye color that is not shared with anyone else in the country. Despite her age, she wears a stony expression on her face. She dresses in gray shorts and a long brown shirt, with patches all over. Despite owning other articles of clothing, she chooses to wear this at all times. She oftentimes wears a large messenger bag on her back, as well as elbow and knee guards. Her shoes are made of rubber.

Ti speaks quite little, preferring to answer "yes" or "no" questions with nods or by shaking her head, and refuses to talk about her family. She has an attachment to grenades, so far as attempting to bring them along with her on a stroll. She is eventually gifted a grenade launcher by Shizu, knowing that she has difficulty throwing them. She is also known to own a ballistic knife.

Ti is a child abandoned by travelers who stayed on the Ship Country thirteen years ago, with the intention to cross the ocean. They became interested in the country, and decided to stay for a year, until Ti's birth. As the couple wished to travel again, they made the decision to leave their child behind, due to the strain of traveling with a child. The people in black eventually find her abandoned in a storehouse, and decide to raise her themselves, renaming her in the process.

Ti's name, Tifana, comes from the name of the ship that arrived 600 years ago at an abandoned floating city. It was intended as a vessel for pilgrimage or migration, but it contained only children under the age of three, as all the civilians on board older than that age had been wiped out by a plague. She is, in a sense, the princess of the country, as she knows the most of the inner workings of the Ship, as well as the people. However, because of her status, the citizens feared her as she was able to wander as she pleased, treating her as a demon, or an omen of disaster.
