The younger sister of the Wakami sisters.
She is cool, beautiful, transcendent, and mature. Also very cautious and a lone wolf. Yet can be emotional around people.
Basically a caring and kind-hearted person, though sometimes a bit sharp-tongued.

She tries to hide it, but she has an inferiority complex toward her sister. It rears its ugly head in when a third party compares the two. However, Shion herself is more than capable and resourceful. Shion is very smart, but Suiren's intelligence level is ridiculous.

She buys a DSLR with the money she earns from her part-time job and names it "Marumie-kun". She just dotes on it. Only when looking into it, she can let her burden go and be honest with herself.

She is firm and precise, and has a very serious personality, but she is essentially timid and clumsy. From an early age, she has been very brilliant and able.

Surrounded by comparison with Suiren, who always gets more favours, she felt that there was no one who could see her as who she is. She grows less interested in others, building walls with the outside world.
