Aerle is a blue feline beastkin character created to capture the atmosphere of Plum's instrumental track 'R.' He possesses both a mysterious coolness and a cozy, unexpected charm. Although male, his overall calm and cautious personality gives him an androgynous, femboy-like appeal. He has sclera that are black instead of white. His blue pupils shine like jewels within that dark background. Physically, he stands about 157cm tall and weighs around 30kg, possessing an extremely frail and slender build. Aerle's fashion consists of comfortable sleepwear or undergarment styles. Just below his fluffy chest fur, he wears a soft scarf. He maximizes his cuteness by wearing striped cotton-candy-colored socks that reach above his knees. He has white and blue wings on both sides by default, but these are merely decorative. His soft, tactile paw pads emit a blue bioluminescent glow in the dark. His age setting uniquely reflects the sentiment of the song. Based on 2019, the year 'R' was released, he should be 7 years old, but to express the deep, adolescent atmosphere of the song, 9 years were added from the moment he was born. Therefore, his official age is 7+9 years old. Because of this, when asked his age, he has a habit of answering, "I am seven-plus-nine years old...!" Just as the song 'R' races forward like rapid fire yet simultaneously tugs at the heartstrings, his daily behavior is one beat slower than others, full of clumsy and airheaded charm. He is a huge sleepyhead who spends an average of 12 hours a day in a fluffy bed. He loves cozy things so much that his mood improves the moment he sees anything resembling a cushion. When he falls into a deep sleep, he unconsciously farts often and is teased by those around him for being a 'fart-meister,' but strangely, the smell is not foul but a fragrant peppermint scent that causes no discomfort. Although he is an extreme klutz who hates moving, he is surprisingly skilled at digital instruments. Among them, he most enjoys and excels at playing the theremin, which produces mysterious electronic sounds by adjusting wave patterns in the air. His taste in music is also firm; he enjoys listening to Alan Walker's electronica tracks and is deeply immersed in the sophisticated mechanical sounds of Vocaloid. In this way, Aerle is a charming character who hides a high level of musical sensibility behind a dim-witted and cute daily life. (Aerle also suffers slightly from asthma and extremely loathes smokers. Even the smell of cigarettes can make him agitated; at best he might pout, and at worst, he might cut ties entirely...)
