Shingo is the fastest of the guard and is considered to be the wisest of them. She often gives the other guard-members advice and guidance. She is a little older than the others, but it doesn't stop her from performing well in battle. She often can come across as snappy and strict, but always looks out for the well-being of her friends. Her voice is slow and smooth, and her words can often sting. She will often drag out her syllables when she speaks.
