Aine Yūki (友希あいね) is one of the two protagonists of the Aikatsu Friends! series. She is a student of Star Harmony Academy, initially having attended the normal division before transferring to the idol division. Aine is a cute-type idol whose preferred brand is Sugar Melody. Along with Mio Minato, the two are a part of Pure Palette.
Aine has fair skin and vibrant red and orange eyes with flecks of yellow. She has thickly curled cornflower lilac-pink hair with a chardonnay-orange ombre. Her bangs are straight cut and worn with a sky blue headband that has a bow on the corner, while her short curled forelocks are worn over her shoulder beneath the ear.
As of season two, Aine's hair has grown slightly longer and curlier, which she now tied up slightly at the back, with some strands falling over her shoulders on either side. She has replaced the headband with a sky blue bow, which is worn on the right side of her head.
At the age of two, Aine had her small amount of hair tied up with a mini sky blue bow. As she grew older and had more hair, Aine adapted the twin pigtail hairstyle, held by mini bows as well. Reaching the age of eight, Aine let her hair down to shoulder's length, in which had developed great volume, and retained the bows, but this time as hairclips. Her final hairstyle change before her current one was when she reached the age of eleven, in which her side ponytail hairstyle was held up by a ribbon-bow that is the most similar to the one she has on her current headband.
Aine is a positive and cheerful person with a kind heart who is known for her ability to make friends easily.
While working at Penguin Café, Aine met Mio by coincidence and started to get to know each other. Mio then asked Aine to join her on her Aikatsu! activities, but Aine is starting out rough.
- They instantly bonded after Aine made a delivery to drop off the lunch she ordered, and after forgetting to pay for the food she later returned to Penguin Cafe. After playing with Aine and her little brother she came to the decision to ask Aine to team up with her for the upcoming Aikatsu event and Aine accepted, now seeing them as friends.
- Tamaki is Mio, Aine, Maika and Ema's manager.
