OVA
Description
Maria Tarō Sekiutsu is an illegal immigrant from an unspecified country, with visual cues and complexion suggesting a possible Filipino origin. She secured her place in a Japanese school by purchasing the birth certificate and student identity of a male student named Tarō Sekiutsu, rendering her legal status male despite being biologically female. The name "Sekiutsu Tarō" originates from the phrase "seki uttaro," meaning "I'll sell my name," alluding to the transaction that granted her this identity.

She exhibits an optimistic and cheerful demeanor, marked by immaturity and innocence. This often leads to misunderstandings and prompts her to say and do unpredictable things. Maria typically views situations from a detached, outsider perspective and refers to herself in the third person. Her positive outlook inspires others to protect and help her. She consistently avoids wearing shoes or panties.

In appearance, she has dark skin and short hair, and she is the shortest student in her class. Her school uniform is visibly too small. She lives in severe poverty, sharing an abandoned apartment building with dozens of other illegal immigrants. This upbringing fuels her habit of collecting food and discarded items from the ground or garbage, captivated by what she sees as Japan's overflowing abundance.

In class, she is designated as student number 8, though an alternate source lists her as number 11. Most people call her "Maria," while Kafuka Fuura often uses "Mataro," a nod to a children's book character. She regularly delivers the final line in manga chapters and anime episodes, offering a closing remark or joke.

Her relationships are largely positive. She shares a strong bond with Kafuka Fuura thanks to their mutual optimism and often aids Chiri Kitsu during various rampages. Her backstory involves arriving in Japan and integrating into the class, where she is generally regarded as cute and treated with kindness.

Throughout the series, she participates in events such as imagining herself as the straight man in a comedy duo and slapping all the fools in one chapter. Her exact age is unknown, but she appears significantly younger than her classmates, taller than elementary students but shorter than another student named Meru.
