Romi

Romi is a girl with light skin, pink eyes and hair. While her outfit can be easily recognized.

Romi's hair is arranged into a ponytail style, with pink scrunchies. She wears a white shirt with buttons and a dark scarlet pink collar with the pink border, with a pink bow ribbon holding the Magic Bell. She wears a pink skirt with a round heart polly belt pocket used to hold the Magic Catcher, and occasionally the Teeniepings. She wears long, white socks and pink shoes.

Romi is a playful, clumsy and curious girl. Proud and cheerful, she is quite messy and likes to fool around and have fun with her friends, whom she loves a lot. She is nice and generous, and likes to help the people she loves when they are in trouble. With a smile bright like the sun and her irresistible attitude, she is easily forgiven for her actions. She is also shown to be fearless as shes not afraid to risk her life and face danger in many occasions throughout the show and is very responsible as she takes her missions to catch teeniepings very seriously but she also doesnt forget to spend some quality time hanging out with her friends and doing other stuff during her missions.

Heartsping, as part of her royal Teenieping role, is Romi's personal Teenieping, meaning she is in charge of staying and taking care of her, ensure her safety, and also to simply entertain and spend time with her. As such, Romi and Heartsping spend a lot of time together, especially in the Emotions Kingdom during Romi's childhood, where they become very close.

Heartsping is a pink heart-themed Teenieping. She has pale pink fur, pink eyes, and a pigtail style with curled and pink at the end, with a pink fringe and tints at the bottom.

She also has a pink collar with a round gold badge, her golden Royal Teenieping sign on her chest, and a long heart tail with gold on it. Her prop is a gold and pink hand mirror with a pink ribbon shaped like a heart.

Heartsping is very nice and kindhearted. She has a very girly and feminine attitude, likes to act cute, and occupies herself with various activities, like having tea with friends or doing cute poses.

She also loves her friends very much: she likes to make them happy, even though it sometimes makes her hide things or follow them even though she doesn't want to, she may also make others unhappy sometimes.

She can be pretty immature like her Royal Teenieping colleagues, as she likes to follow her instincts without thinking of the consequences, but she can also be more mature when the situation demands it. In Twinkle Catch! Teenieping, she acts very strict towards the Royal Teenieping students and is dedicated to teaching them about various subjects and imposing order when needed.

Heartsping is also very smart, given her upbringing as a Royal Teenieping, possessing excellent skills in physics and nursing. She also has extensive knowledge of nearly every Teenieping in the Emotions Kingdom, as she can describe who they are and their abilities.

Before she met Romi, she is quite introvert and listens to a Mysterious Teenieping, stating that Teeniepings and Humans cannot be friends. She was quite shy and nervous, ignoring Romi and Marie's request.
