Shiro is a bubbly and clumsy girl. She has lots of energy, most likely from the fact she eats nothing but sweets. She is shown to have loved sweets throughout her life, particularly cookies, and her sweet tooth may be her way of staying connected to her childhood. She has a very childlike outlook on life, and this leads to her mind not understanding much; Shiro doesn't even understand the concept of a girlfriend and has a simplified outlook on love.
