Kelsey, also known as superhero Glitter Oranje or Glitter Sunny, is a central character. A 14-year-old student at Rainbow Hills Middle School, she excels fiercely in volleyball. Her family runs an okonomiyaki restaurant, reflecting her Osaka roots and Kansai dialect in Japanese, adapted in English localization. Her personality blends tomboyish energy with passionate loyalty. Confident and playful, she acts as the self-proclaimed class clown, using humor to ease tension. Despite her bold exterior and occasional teasing of friends like Lily, she shows profound loyalty and acts decisively to protect others. She openly dislikes overly cute or sentimental things, finding them cringeworthy, yet secretly enjoys cute items like gorilla plush toys. Academically less inclined, her strengths are athletics and physical challenges. Kelsey's journey starts when she aids a nervous Emily during a classroom introduction, sparking their friendship. This bond strengthens when Emily supports Kelsey overcoming volleyball practice struggles. Her pivotal moment comes witnessing Emily, as Glitter Lucky, battle a Buffoon monster. Inspired by Emily’s refusal to surrender and recalling their shared "sweating, not crying" mantra, Kelsey breaks free from magical despair to defend her friend. This bravery summons a Glitter Pact, enabling her transformation into Glitter Sunny. Initially hesitant and embarrassed by the frilly transformation, she gradually embraces her role. As Glitter Sunny, she commands fire-based powers. Her attacks include Sparkle Fire, generating a fireball she strikes like a volleyball spike, and its upgraded form Sparkle Fire Inferno. She participates in group attacks: Tiara Mode Torrent, Rainbow Burst, and Royal Rainbow Burst. Possessing superhuman strength, she performs feats like lifting Buffoons single-handedly or creating earthquakes with punches. Her fighting style is direct and acrobatic, reflecting her athleticism. Her transformation involves inserting a Glitter Charm into her Glitter Pact while reciting specific phrases, culminating in fiery effects and her final pose with the catchphrase: "When you mess with me, you're playing with fire! I'm Glitter Sunny!" Variations include Tiara Mode (gold crown, altered accessories), Princess Sunny (elongated hair, ruffled cream dress, halo), and Royal Mode (curled hair, feathery cape, white wings). Relationships motivate her core. She shares a protective bond with Emily, whom she describes as a scatterbrain but values as a true friend. She frequently teases Lily yet acknowledges her artistic talent. With April, she maintains a friendly rivalry rooted in mutual athletic respect, often competing while offering support. She admires Chloe for academic and leadership skills. Outside the team, she interacts with volleyball teammates, cheering them when not playing. Her family includes parents Marina and Bertram, and younger brother Roger. Her development progresses from a hesitant recruit prioritizing volleyball to a committed warrior balancing duty with passion. Key growth includes overcoming her fear of heights during missions and participating in global adventures, like a magical trip to the Amazon. These experiences reinforce her themes of perseverance, courage, and friendship's power. Trivia notes: Her name Kelsey means "brave" or "ship's victory"; her original name Akane Hino means "sun field/madder red." The circular shape of her Glitter Charm references the Japanese flag. She is the second Glitter Force member and shares her original surname with Sailor Moon's fire-wielding Rei Hino.
