Description
Shiori Motoya attends Seirei Private High School as a female student, aged 15-16 in Season 1 and specifically 16 in Bloomy*Cafe content. Her birthday falls on March 26, establishing her zodiac as Aries and blood type as A. Her real-world appearance features dark brown eyes with a distinctive beauty mark beside the right eye, complemented by slightly wavy dark brown hair reaching chest length. She typically styles this hair with an upper crown braid incorporating several strands and pinned-back bangs. In contrast, her avatar Shiori displays bright teal green eyes accented by cyan eye marks. The avatar's short silver hair curls at the ends, adorned with pale pink highlights shaded in blue. Avatar Shiori's bangs are gathered and tied to the right, featuring two long curly strands—one silver and one pale pink—intertwined.

Academically, Shiori excels notably in history and Japanese. Her interests gravitate towards mechanics and reading. She possesses sharp observation skills, evidenced by deducing patterns like Mao Otoha's consistent preference for clothing with bows. Shiori specializes in conducting quizzes, frequently initiating them with her signature phrase, "Now here's a question for you!" She acknowledges limited athletic prowess, citing only the ability to leap over a vaulting box at its shortest height. Initially characterized as a shrinking violet uneasy with attention, she cultivates determination through idol training, sparing no effort to achieve her goals once committed.

Shiori shares a deep bond with Mao Otoha as childhood friends since primary school, serving as Mao's first friend. She deeply admires Mao's qualities, offering both emotional support and practical assistance during Mao's activities as the secret avatar Hana. Mao, in turn, relies on Shiori for calmness and authenticity, appointing her as a companion for critical announcements. Shiori also knows Ruli Tamaki through Mao and respects Kyōko Umekōji's elegance, aspiring alongside Mao to emulate Kyōko's Yamato Nadeshiko traits. She maintains a friendship with Kanade Otoha, known since before high school.

Shiori's journey into idol activities begins with her decision to debut alongside Mao and others. Despite initial self-doubt about her suitability, she undergoes rigorous non-stop training aided by Mao, culminating in a successful debut performance. Remarkably, she unexpectedly defeats the experienced Ruli Tamaki in her first battle stage. Her preferred Dressia type is Story, influenced by a lifelong love of fairy tales—particularly Alice in Wonderland—which inspires her view of idols as story protagonists. Her key Dressia is Wonderland Tale.

Shiori appears throughout the *Aikatsu Planet!* television series, including the episode "My Revolution" (Episode 9), and the 2022 film *Aikatsu Planet! The Movie*. The film's narrative centers on a "Gratitude Festival" where idols express thanks to fans through diverse performances like bands, musicals, and cliff-climbing events. She also participates in Bloomy*Cafe, an in-series established local hangout for idols.
