Everything is a Transaction. That's how Tokoro views life. Everything lost is someones gain, and every gain is someones loss, regardless of what it is. It makes her horde of secondhand books so much more rewarding to look at, knowing that each used to be someone elses favourite treasure. This view does make her less enticing as a friend, but the hard exterior can be worn down with enough charm.
Favourite hobbies include: Reading, Digesting prey whilst reading, working in her shop whilst digesting prey, working in her shop whilst digesting prey and reading, gambling, everything mentioned so far as prey (Audiobooks work best when she's prey), collecting Pokemon.
A little bit more about her: She's 18 years old, stands at 5'5" out of shoes, and weighs 90Ib.
