DJ (full name Dhananjay Arora) is the sweet, earnest protagonist of *Superfish*. He's an 18-year-old human with a gentle and innocent demeanor — the kind of person who genuinely tries his best even when life puts him on the spot. He loves writing, reading, music, and (fittingly) the in-world hero Superfish, which hints at his idealistic and imaginative side. On the flip side, he's easily stressed and doesn't handle pressure well, especially from his teacher or unexpected attention. That mix of soft-hearted sincerity and relatable anxiety makes him a very endearing main character — someone you root for because his goodness feels real, not polished.

Sebastian (also known as Superfish) is a powerful, 19-year-old witch with a highly charismatic but cocky and egotistical personality. He loves burgers, music, and dancing, while strongly disliking embarrassment, rats, and bad drivers. He can be snappy and blunt, but masks deeper vulnerability.
