Description
Solulu serves as the white cat mascot for Kagayaki Corporation and Pri☆Chan Land. She possesses yellow eyes, light blue lashes, and white fur. Her attire includes a sky blue diamond on each ear, an orange shawl with a matching bow secured by a gold brooch, and a gold ring encircling the top of her tail. In her idol mascot form, she gains long, straight hair reaching below her waist, featuring bangs parted to the sides and a loose central strand, plus a tented hair layer extending to her shoulders; a distinct strand of hair sticks out on her right side.

Her personality is predominantly calm and observant, yet she displays energetic traits matching her partner Alice Kagayaki when needed. Solulu demonstrates kindness and empathy, notably comforting Rabbily during insecurity. Memory loss in Season 3 caused her idol form to exhibit a separate, more mysterious aura of nobility and gentleness. She quietly supports others and often teases Alice for forgetfulness or clumsiness.

Solulu is Alice Kagayaki's dedicated mascot, typically perched on Alice's shoulder. Their bond dates back to Alice's infancy, with Solulu consistently intervening to protect or support her during crises. Key shared history includes Solulu saving Alice's performance in Episode 128 and aiding her during an Illuminage Live, actions Solulu initially forgot due to memory loss. Their connection deepened when Alice physically clung to Solulu during a fall, leading them to arrive at a circus together. Solulu later chose to leave Alice to address a larger threat, sharing an emotional farewell where they appeared as a constellation of their Petite Mascot forms. Alice's sun earring originally belonged to Solulu.

Her relationship with Luluna is complex, rooted in conflict. An argument during the twins' infancy led Solulu to reject Luluna's ideals, provoking Luluna to erase Solulu's memories while Solulu was distracted protecting Alice from a fall. Solulu regained these memories in Episode 141. Though she appeared to cooperate with Luluna's hostile takeover in Episode 149, her true motive was enlisting Luluna's help to contain a destructive "bug hole." Their reconciliation culminated in a joint heroic sacrifice in Episode 152, abandoning their physical forms to become a permanent shield against future bug holes threatening Earth.

Solulu shares connections with Eve Kagayaki, Alice's twin sister, appearing before Eve during doubt or need to offer guidance. Historically, Solulu, Luluna, Alice, and Eve coexisted peacefully before their separation. Post-conflict with Luluna, Solulu informally assumed mascot responsibilities for both twins. Her name incorporates "Sol," Latin for "sun," contrasting Luluna's lunar associations and reflecting their thematic duality.

Her birthday is February 22nd, coinciding with Japan's Cat Day, which she shares with Ushimitsu from Idol Land PriPara. She ranked 4th in the February 2021 character popularity poll. Her narrative spans the anime's third season, debuting in Episode 103 after a cameo in Episode 102.
