She's a human who looks like a normal ninja with teal hair. She sports a gray baseball cap with the color blue under the tip of the cap. She wears a dark colored garb similar to ninjas, but with baggy pants and dark gray shoes. She also wears a dark blue mask to cover her mouth as well as a dark blue bow around her waist. Under the ninja garb, she seems to wear a gray long-sleeved T-shirt and gray pants.
As such her namesake, she is pretty shy. It's said that if one talks to her, she'll vanish in a cloud of smoke, usually leaving behind an object as a decoy. However, when she is fighting her enemies, she seems to play along with them, even gloating when Vormulax hissed to her. Much to her shy nature, the only responses she makes are quiet giggling.
When Mikayla became one of the protectors of Lakewood Plaza, she and Shy Ninja are shown to have a friendship or partnership.

- She's said to be very athletic, being the local high school's baseball champion. She can hit the ball with great speed and run around the bases so fast [one] can't even see her.
- Her weakness is that she hates being put on the spot or having attention called to her.
- She would have been Enid's rival but the story was not made.
