Shiina has long, straight and red-pink hair tied into long and thin twintails, which are seen suspended around her face out with two butterfly-shaped orange ties or pins. Her fringe is quite long, reaching to her eyebrows. She has light green eyes and she is often seen wearing her school uniform. It consists of a white shirt, and a black cardigan over it. A blue tie is in a bow with an orange-checkered skirt and brown shoes.
Shiina has a quite childish and cute personality, and it seems like she is very shy as her speech usually ends up with her stuttering and fidgeting. She can be mature sometimes and she is a little airheaded.
She always gets nervous when Seiya is nearby and it looks like she has a crush on him and is able to look past his behavior and see the good side to him.
It is hinted that she has a crush on Seiya, and even thought that she doesn't show it that much, but she wants to spend as much time with him as possible, and she said that she gets very happy and glad when she gets to spend time with him. But she can get a bit jealous when another girl is with Seiya, as seen in episode 8, that she got jealous when he (actually Tiramy) was ''dancing'' with Kanae Tsuchida.
- Her pigtails and small figure resemble Hachikuji Mayoi from the Monogatari series. Another similarity is the stuttering, though in Hachikuji's case, she does it on purpose. She also resembles Wendy Marvel from Fairy Tail for the same reasons, both characters even share the same English VA.
