Description
Czechia appears as a young woman with long dark hair, usually secured in a bun, though she wore it longer in pigtails during her youth. Her distinctive purple eyes stand out, and she measures about 162 cm tall, notably shorter than Slovakia, reaching only to his chin. She typically wears a light-colored dress shirt with a ribbon-like tie and knee-high boots, though a chibi-style illustration depicts her in a darker military uniform.

Her personality is serious, patient, and hard-working, characterized by meticulously planning every move. She views historical milestones like independence from Austria-Hungary as a "starting line," reflecting her forward-looking perspective. Czechia possesses a delicate and unique artistic sense and takes significant pride in her accomplishments. In her younger years, this pride manifested as haughtiness, particularly when outperforming Slovakia in various domains, causing him to cry while she reveled in her superiority. While this behavior has tempered with age, she maintains a composed and goal-oriented demeanor, which Slovakia still describes as "haughty."

Her relationship with Slovakia defines much of her background. After gaining independence from Austria-Hungary, they formed Czechoslovakia. They immediately clashed over the country’s name—Slovakia insisted on a hyphenated version to emphasize equality, while Czechia registered it without a hyphen, leading Slovakia to accuse her of domination. This disagreement persisted for decades, resurfaced after their liberation from Russia’s sphere of influence, and ultimately culminated in their peaceful separation. During their time apart, Czechia initially relished the cleanliness and independence but later realized the practical challenges of living alone, such as having no one to hand her a towel. Upon reuniting, she acknowledged Slovakia’s positive traits, prompting an enthusiastic hug from him, though she attempted to escape his embrace. Despite their reconciliation, they maintained separate nations, with Czechia later adopting the shorter name "Czechia" to replace the "mouthful" Czech Republic, though Slovakia found it cuter.

She harbors a professional rivalry with Hungary over spa culture. Czechia criticizes Hungary’s advertisements for relying on sex appeal rather than the quality of the spas and believes her own contributions to the industry are more passionate and substantial. She also encounters Italy during his quest to master bath cultures, boasting that her spas are superior and calling herself a "major spa country."

Her interactions with other nations include lingering hostility toward Austria due to historical grievances, though trade relations prevent overt conflict. She is visibly terrified of Belarus, as indicated on Belarus’s relationship chart. Additionally, she shares an unresolved debt issue with Liechtenstein, flinching when reminded of the owed money.

Trivia notes reveal that the creator initially conceptualized Czechoslovakia as a single male character or a pair of brothers, but later shifted to a female Czechia after considering that "girls are cute." Early development notes also suggested basing her character around rivalries with Germany and Austria.
