Ginko Momose is a main character from the Love Live! Hasu no Sora Jogakuin School Idol Club Bloom Garden Party project. She is a second-year student at Hasunosora Girls' High School, having enrolled as part of the 104th generation, and is a member of the unit Cerise Bouquet. Her image color is known as Heavenly Blue.

Ginko comes from a family that runs a workshop in Kanazawa specializing in Kaganui, a traditional form of embroidery. She has a deep personal connection to the school's idol activities because her grandmother was a member of the Performing Arts Club, the organization that eventually evolved into the current School Idol Club. This familial link is the primary source of her motivation; she aspires to become a school idol not merely for the sake of performance, but as a way to inherit and continue the traditions her grandmother cherished. A specific and powerful memory is her grandmother singing her a song called "The Song of the Other Side," which she loved and which later inspired her journey.

In terms of personality, Ginko is a serious and formal girl who holds a profound respect for history and traditional crafts. She enjoys visiting Shinto shrines, Buddhist temples, and coffee shops, often taking long walks to admire historical architecture. Her casual clothing frequently consists of kimonos, reflecting her aesthetic preferences. Despite her strong connection to tradition, she struggles with social situations. Having grown up surrounded mostly by older people, she has little experience making friends her own age and initially finds it difficult to connect with her peers.

Ginko's personality contains a notable tsundere aspect, particularly in her interactions with her classmate Kaho Hinoshita. She is often overwhelmed by Kaho's open and positive nature, which can cause her to react with stubbornness or denial, especially when receiving compliments. Beneath this exterior, she is afraid of failure and of annoying others, which leads her to hide her true feelings and try to go with the flow to avoid being seen as strange.

Regarding her role in the story, Ginko initially joined the Idol Club out of a desire to connect with her grandmother's legacy. However, she experienced a crisis of purpose when she could not find her grandmother's favorite song, "The Song of the Other Side," in the club's repertoire, leading her to consider leaving. Her fellow club members, led by Kaho, researched the club's history and discovered that the song had not been lost but had evolved over decades into a new piece titled "Reflection in the mirror". This revelation reaffirmed her connection to the club's traditions, and she ultimately joined Cerise Bouquet.

Ginko's key relationships are central to her development. Her bond with Kaho Hinoshita is particularly important, as Kaho's persistent encouragement helps Ginko come out of her shell. Furthermore, her family heritage directly contributes to the club. After discovering a set of old, damaged performance costumes in a warehouse, it was Ginko who brought them to her family's workshop, where her grandmother helped repair them, physically linking the club's past and present. Her skills in embroidery and design are notable abilities, and she eventually takes on the responsibility of creating stage costumes for the entire club. She is also skilled in traditional Japanese dance.

Ginko's development throughout the story sees her shift from a girl fixated on preserving a specific past to someone who actively creates new traditions as a school idol, using her unique skills to support her friends and build a future for the club that honors its history.
