Cure Lillian

Cure Lillian (キュアリリアン, Cure Lillian)? is Mayu's Pretty Cure alias. She transforms using the Shiny Cats Pact. Lillian prefers not to hurt the Garugaru, and instead uses methods that will gently save them.

Nekoyashiki Mayu (猫屋敷まゆ, Nekoyashiki Mayu)? is one of the four main Cures in Wonderful Pretty Cure!, and a second-year student at Second Wangan Middle School. She is also Yuki's owner.

Mayu transforms into Cure Lillian (キュアリリアン, Cure Lillian)?. Together with Cure Nyammy, they form the duo Nyanderful Pretty Cure (ニャンダフルプリキュア, Nyanderful Pretty Cure)? until episode 30.

Mayu has dark brown hair styled into a left-side ponytail and held by a teal scrunchie. Her eyes are burgundy. She wears a pale yellow top with a scalloped bottom and two green buttons and a cropped teal jacket with elbow-length sleeves over it. She wears a prairie skirt with pale green, light green, and sea foam tiers and a pale green ruffle at the bottom. Her shoes are brown and pink with straps around the heel and light brown soles. She wears thick cuffed pink socks. After becoming a Pretty Cure, she wears her Shiny Cats Pact on her left side.

As Cure Lillian, Mayu's hair turns light teal and is styled into a slightly left ponytail that appears thicker at the top. She wears a teal headband with a small teal top hat featuring a purple band, a white frilly brim, and a pink bow in the back. Her eyes turn purple, magenta, and light green with light yellow pupils and she wears dangling pearl earrings, along with a blue choker with a matching bow in the back. She also wears pink eyeshadow. Her dress is long and white with a teal stripe lining the skirt, and pink shoulder straps. The dress is shorter near the front and slanted towards the left. A teal and pink-striped band with white and teal ruffles line the top, along with a blue and pale yellow-striped bow featuring a green heart brooch in the middle lined in gold. The teal sash is covered in the front by the bodice. Near the bottom of the skirt is a large teal and pink ribbon tied at the right with a part on the right being longer than the other. She also wears white arm warmers with teal bands at the top and bottom and ruffles at the ends, as well as long light teal boots with cerulean toes and soles that are topped with teal ribbons around the top and magenta hearts in the middle.

Mayu is a socially awkward girl who wants to make lots of friends but runs away from any social interaction. She is good at applying make-up, and sewing. Although initially timid, Mayu becomes braver due to her desire to help her friends. Mayu tends to get hyperfocused whenever she is knitting or performing a task, to the point that she doesn't even hear whenever someone is talking to her.

Once Mayu has opened up to her friends, it's revealed Mayu can be quite mischievous, teasing Satoru about his crush on Iroha. Mayu is also very kind and patient, always willing to slowly help Yuki overcome her lone-wolf tendencies. Mayu even has a stubborn side, as shown when she refuses to let go of a Sea Turtle Garugaru, as she so desperately wants to help calm it down.
