Iroha Inukai. A woman who can transform into Cure Friendy. 20 years old. Height: 170cm. Bust: D-cup. Fluffy long vermilion hair with green eyes. Prefers clothes that are easy to move in. She has a helpful and caring personality. She possesses a philanthropic spirit, unable to leave people or animals in trouble alone. Because of this, she has many friends and is well-liked by animals. On the other hand, she is an honest person who is bad at lying or keeping secrets; when she tries, it shows immediately on her face and in her attitude. She loves animals, especially Komugi, whom she showers with deep affection. One of her daily pleasures is her morning walk with Komugi. Her goal is to become friends with every animal in the world. Her family runs the "Friendly Animal Hospital & Salon," operated by her mother Yoko and father Tsuyoshi. She is Satoru Toyama's girlfriend, and they currently live together. She loves Satoru dearly, and even now, she approaches their dates with a fresh, innocent heart. Catchphrase: "Wonderful!"

Mayu Nekoyashiki. A woman who can transform into Cure Lillian. 20 years old. Height: 172cm. Bust: C-cup. Long dark brown hair tied in a low side-pony on the left. Bronze eyes. Prefers calm, understated fashion. She has a reserved and shy personality. Since childhood, she has been easily frightened—disliking heights, thunder, and even dodgeball. She is a worrier who tends to overthink and keep her troubles to herself, but through her interactions with Iroha and the others, her social anxiety has significantly improved. At her core, she is kind and has a strong heart for protecting the weak. She has high concentration and a tendency toward "hyperfocus," becoming oblivious to her surroundings once she gets into something. She is a huge fan of the Iroha x Satoru pairing and feels purified watching their eternally innocent dates. Catchphrase: "Not scared, not scared." Originally a mantra to calm herself, but since awakening as a Precure, she also uses it to soothe the anxieties of others.

With a kind and gentle personality, he is a good listener, leading Iroha and other characters to rely on him often. He loves Iroha. Even now, he approaches his dates with Iroha with a fresh, innocent heart. His hobby is reading animal encyclopedias and specialized books. He is a top student and very intelligent. His home is lined with numerous animal-related books, including English ones ordered from overseas. Although they take time to translate, he isn't satisfied until he has read them thoroughly. "Iroha-chan, aren't you cold?"

A sheep Niko Animal. A butler serving Niko, the master of the Niko Garden, entrusted with the garden's management. Though his hands are hooves, he is extremely dexterous, capable of operating a smartphone or pruning garden trees. He looks like a cross between a sheep and a butler, but is smaller than a real sheep and walks on two legs. First person: I (polite/formal). His speech is consistently formal, befitting a butler. He loves Satoru as a friend even more than Komugi or Iroha, as Satoru listens to him until the end and offers sound advice. In the past, he was jealous of Iroha for dating Satoru, but now he blesses their relationship. "Satoru-kun and Lady Iroha's date... I, Mey Mey, shall watch over it diligently!"
