Ochaco is an outgoing, bubbly and lively person who thinks about everything positively, while still being objective enough to seeing her own and others' flaws and virtues. She is very harmonic and empathetic in general, nice and friendly to those she meets, and will also try to help or defend anyone that previously came to her aid, especially to her dear ones. However, Ochaco can be awfully blunt without being aware of it at times.

Similar to Izuku Midoriya, her reactions tend to be exaggerated and humorous: Ochaco often becomes amused at certain personality traits and quirks others may exhibit, sometimes to the point of bursting into laughter which she tries to suppress to some extent. Because of her humble background, she easily gets excited or surprised over little things and may even lose her composure when faced with actual luxury, to the point of nearly fainting. Bonus materials have depicted Ochaco as stingy, since she goes to extreme lengths to save money.
