Komugi transforms into Cure Wonderful (キュアワンダフル, Cure Wonderful?). As a dog, she ends her sentences with "~wan" (「～わん」, "~wan"?). Her catchphrase, which she adapted from Iroha's, is "Wonderful~" (「わんだふるー！」, "Wonderful~"?).  As much as she tries, she can't be friends with Nekoyashiki Yuki.

Inukai Iroha (犬飼いろは, Inukai Iroha?) is one of the four main Cures in Wonderful Pretty Cure!. She is Komugi's owner.

Iroha transforms into Cure Friendy (キュアフレンディ, Cure Friendy?). Her catchphrase is "Wonderful!" (「ワンダフルー！」, "Wonderful!"?), which Komugi likes to imitate. She is the first friend of Nekoyashiki Mayu. She loves animals and wants to be friends with all of them.

Nekoyashiki Yuki (猫屋敷ユキ, Nekoyashiki Yuki?) is one of the four main Cures in Wonderful Pretty Cure!. She is the Nekoyashiki's adopted pet cat and the mascot of The Pretty Holic. When becoming a human, she considers herself the "older sister" of Mayu and her loyal protector.

Yuki transforms into Cure Nyammy (キュアニャミー, Cure Nyammy?). She is very judge mental and aloof, and isn't interested working along side Iroha and Komugi. Due to her feline instincts, she is more aggressive than the others when fighting a Garugaru. Although she overcomes this and her aloofness.
After this, she seems sensitive and shy, just like her owner.

Nekoyashiki Mayu (猫屋敷まゆ, Nekoyashiki Mayu?) is one of the four main Cures in Wonderful Pretty Cure!. She is the owner of Nekoyashiki Yuki.

Mayu transforms into Cure Lillian (キュアリリアン, Cure Lillian?).

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. She hates Yuki's overprotectiveness.

Yuki woke up in Mayu's bed. She's been awake, slowing watching her owner sleep. She licked her face. Mayu woke up, smiling. "Aw, my little kitty, Yuki!" She snuggled with Yuki. Mayu cuddled Yuki tightly and got dressed. She stared at the mirror and smiled, "I know that today's going to be a good day!" Mayu said. "Isn't that right?, Yuki?" She asked. Yuki didn't respond. She stared back at Mayu, Annoyed. She found Mayu's friends annoying. They were talkative, happy and friendly. Maybe a little too much for Yuki.  Especially Komugi. What an annoying mutt. Yuki often thought of Komugi. She quickly transformed into a human to prevent Komugi from "playing" with her. Komugi was still able to hug Yuki. "Hey, Yuki!" "It's so cool how you're a precure with us!" "Let's play together, Wan!" She said with a beaming smile which only angered Yuki further. Yuki started to pull away from Komugi's grasp, but she was still clinging onto her. "Come on!" "Let's play!" Said Komugi. Yuki rolled Her eyes as Komugi approached her owner, Iroha. Yuki didn't like Iroha much either, but she knew that she was not as bad as Komugi. Iroha waved to Mayu and Yuki. Komugi and Iroha rushed over to hug Mayu. Which annoyed Yuki further. Her anger was so strongly expressed. Then they both rushed over to hug Yuki. "Hello, Yuki." Said Iroha. Mayu noticed how much Yuki frowned, Mayu hugged Yuki and tickled her. "Aw, is Yuki angry?" Teased Mayu. Yuki couldn't help but laugh as Mayu continued to tickle her. "Coochie coochie coo!" Mayu teased.  Yuki laughed as tears rolled down her face. Mayu finally let go of Yuki. Mayu hugged her and smiled softly. "I love you so much, Yuki!" Yuki smiled and said softly "I love you too, Mayu-Chan." Said Yuki.  Yuki felt off.  She clutched her chest as her eyes clouded over. Cruel thoughts filled her heart and soul. She looked at Komugi with a look Komugi never saw before. Komugi  tried to hug her, But Yuki swatted her hands away. "Go away." She said.
"But why?" Asked Komugi.
"You stupid mutt!" "Just get away!"
"Hey, don't say that to her!" said Iroha.
"Who's going to stop me?!" Cackled Yuki.
