She has a hasty and fiery temperament and is highly sensitive to trends. She loves spicy food, lives on fried chicken and iced americanos, and is often depicted as being addicted to her smartphone. There is also a gimmick where she is obsessed with internet speed and IT gadgets. Because she is constantly caught up in China's eccentric antics, she inwardly thinks, "I wish she'd just drop dead already..." Among the Flag Musume characters, she is often given the most positive attributes, such as being "the sane and rational one," which led to some confused reactions among Korean netizens. However, since the author is Japanese, it isn't exactly a "nationalistic pride" trope. She is generally interpreted with the "Girl Crush" vibe common in K-POP idols or portrayed as a "Cool Beauty" with an introverted and indifferent personality. It's suspected that the stereotype of Koreans being somewhat blunt influenced this image. Separately, reflecting the Korean trait of harsh "fact-bombing" and indirect sarcasm through metaphors, there was a work where Japan came to tease Korea after she was eliminated in the 2026 World Cup group stage, only to be genuinely terrified when Korea entered "Menhera mode" and unleashed a barrage of savage sarcasm and self-criticism. [Design Notes] She looks bored. Everyone in East Asia gets along poorly. ☆

While she often shows a generous, big-hearted side, she also frequently engages in eccentric or large-scale antics. She has a strong sense of pride and a gimmick for loving money and wealth. Although she seems to act without thinking, she possesses a devious "Haraguro" (black-hearted) nature. She gets extremely triggered if anyone asks about or mocks her age. She is also depicted as a great cook and has a gimmick where she suffers seeing her country's cuisine get ruined through localization in other countries. [Design Notes] She's a psycho, so you never know what she'll do. She doesn't sweat the small stuff. Even if she looks brainless, she's actually quite devious. She gets pissed if you mock her age. She doesn't care about the little things.

While wearing her mascot suit, she acts like a total troll, constantly provoking others through written notes. However, the person inside the kigurumi is portrayed as having a very weak and timid personality. There are many scenes where she panics when the suit is forcibly removed by those around her. Aside from "loving to tease others" and "social anxiety," her settings are the most flexible, so her portrayal varies across different fan creations. [Design Notes 1] Her social anxiety became so severe that she can only face people while wearing the mascot suit. She admires eccentrics and tries to act like one, but she always ends up spinning her wheels in vain. [Design Notes 2] Japan: "Westerners lol talking about human rights lol" Japan: "Why don't you say that after lowering your crime rate below mine?" Japan: "Dumbass." Japan: "Who do you think you are, pushing your ideology in entertainment?" Japan: "So what? If you want me to do dogeza, I'll do it."
