Main characters

Tropes that apply to them:


  • Adorkable: Especially when she can talk to squirrels.
  • Balloon Belly: Shown in the episodes "Taffy Trouble" and "Rock N' Roe".
  • Big Eater: One episode had her eat a whole lot of hotdogs & several metal horse shoes. However, she can only eat large amounts.
  • Blue Eyes
  • Curtains Match the Window
  • Cute Little Fangs: Mostly off-screen and moreso in promotional images.
  • Expressive Shirt: The skull on her t-shirt shifts expression to match her own, strangely with the exception of it being mostly emotionless for the rest of the episode "Taffy Trouble".
  • Goth: Though she is more of the "I love MCR" than the "I Recite Deep Depressing Poetry" variety.
  • Idol Singer
  • Jerk with a Heart of Gold: She may be sarcastic, grumpy, selfish and violent at times, but she's a Nice Girl at heart and cares a lot about the people she knows (yes, this includes Kaz).
  • The Ladette: As a G-rated example. She enjoys ninjas, monster trucks, car crushers, R-rated action movies, and anything else rough and tough.
  • Little Miss Almighty: She really is the "Goddess of Rock".
  • Little Miss Snarker
  • Ms. Fanservice: Same deal with Ami. Granted, she's a child, you should see what sexy outfits she wore in "The Amazing Kaz-Am".
  • Only Sane Girl: She can be this at times.
    • Not So Above It All: But at times, she can also act goofy and immature as Ami and Kaz are, but not to the extent as them.
  • The Protagonist
  • Really 700 Years Old: At the beginning of time, Yumi is born as the most legendary, hard-rocking, guitar-griding goddess who lives in the mountains and processes her mighty god-like guitar powers. In the present day, she is 900,000,000,000,000 years old, and she is still looks like a young teenage girl.
  • Red Oni, Blue Oni: The red to Ami's blue. but her favorite color is purple.
  • Skirt Over Slacks: She wears a black skirt over what looks like purple bike shorts.
  • Suddenly Fluent in Gibberish
  • Tomboy and Girly Girl: The Tomboy to Ami's Girly Girl.
    • Tomboy with a Girly Streak: Despite her tomboyish personality, she enjoys wearing lovely dresses, going shopping with Ami and even admitted to Harmony that she has pictures of puppies dressed in cute flowers in her room.
  • You Gotta Have Blue Hair: Literally, though it's more of a purplish shade.
