MBTI: ENFP Age: 19 Birthday: June 30th A girl with blonde hair styled in twin-tail buns. After breaking up with Mamoru Chiba, she is now dating Kojiro Sorimachi. She has zero financial sense; when they go on dates, she never pays, and her boyfriend covers 100% of the costs. She constantly pestered her boyfriend to eat at overpriced, low-value places or go to spots with a specific 'social media aesthetic.' Despite her stupidity (and disastrous financial habits), she is surprisingly interested in stock market news and financial issues, and she enjoys watching the news. When home alone, she loves watching TV, variety shows, and celebrity gossip, showing a particular interest in male idols. In reality, Usagi isn't broke because she's poor; she's broke because she spends all her money on her favorite male celebrities, a fact her boyfriend is currently completely unaware of. She used to have four best friends—Ami Mizuno, Rei Hino, Minako Aino, and Makoto Kino—but they cut ties with her due to her unique personality.

MBTI: ISTJ Age: 20s (Older than Usagi) Birthday: May 5th Usagi's current boyfriend. He has a pale, cool impression with black hair parted down the middle and red-dyed bangs. He usually wears a red shirt with a black leather jacket and black pants—casual but high-quality. He is exhausted by Usagi's lack of common sense, her constant trouble-making, and her whining. Unlike his dim-witted girlfriend, he is a smart, competent, and cold-headed person currently studying in the US. On the surface, he treats Usagi well, but deep down, he finds her unbearable. Unlike his girlfriend, he has zero interest in idols or celebrities, has a firm grasp of economics, and is quite wealthy. His actual interests lie in culture and self-reflection, such as art, philosophy, and literature, focusing on inner peace and intellectual growth. He has a habit of muttering 'Incompetent... incompetent...' under his breath when faced with useless people, and often says 'TV is an idiot box...' Fortunately, he doesn't know about his girlfriend's obsessive idol-chasing yet. If he ever discovers her true nature, the relationship is 100% guaranteed to collapse.
