Appearance
As a Puni Bird, Tsubasa is a plump orange bird, with tiny yellow feet, a yellow beak, a beige stomach, red cheek blushes, large brown eyes with red hue, and yellow eyebrows. On top of his head is a twirled shape tuft of hair. He also wears a red necktie.

As a human, he resembles a young boy with brownish-orange hair and brown eyes. The hair covers the left side of his face along with a swirly ahoge. He wears an oversized light orange shirt with a wide collar and a zipper resembling his necktie. He also wears brown shorts, turquoise sneakers with light orange tabs and white socks. Around his right wrist is a thin gold bangle.

As Cure Wing, his hair turns bright orange and is now out of his face. He now has a long thin ponytail that reaches his feet and his ahoge becomes longer, spikier, and slightly darker in color with a small white wing-shaped clip on the right side. Also on the right is a small brown top hat with a magenta band around it tied in a bow. His top is light orange with pale orange sleeves, brown lining, and multicolored buttons running down the front: a magenta diamond, a yellow circle, and a turquoise triangle. A short orange jacket with a dark orange collar and a wing-shaped brooch with magenta ribbons is worn over it. He also wears short light orange and brown shorts with a large orange coattail attached to it with a turquoise and yellow gradient insert in it. His gloves are light orange with a flared cuff and two gold buttons worn over elbow-length orange gloves and his boots are also orange with light orange toes and brown soles. Around his right ankle is a magenta garter that resembles the necktie in his bird form and he also has two magenta spherical earrings on each ear.

Personality
Tsubasa is a hard worker who cares about Ellee-chan. Tsubasa dreams of being able to fly, so he studies very hard in order to make it happen. He struggles to express his emotions, and doesn't like being pushed around. However, Tsubasa trusts those who have faith in him.

Etymology
Yuunagi (夕凪) means "evening calm".

Tsubasa (ツバサ), also written as "翼", means "wing", which refers to Tsubasa's Pretty Cure alter ego, Cure Wing.
