Biography.
1995-2018: Early life and Nogizaka46.
Ikoma was born in Yurihonjō, Akita Prefecture on December 29, 1995. During elementary school, she was bullied, which made her not want to go to school, but she still did so that her mother wouldn't worry. Ikoma had been learning to dance since childhood, and became involved in the show business with the encouragement of her father who encouraged her to audition for Nogizaka46. In 2011, she applied for the Nogizaka46 auditions along with 38,934 other girls. She became one of the 56 candidates who advanced to the final round. As of August, she was chosen to become one of the 36 1st Generation members.
For Nogizaka46's debut single, "Guruguru Curtain", Ikoma was chosen to be the center in the song's choreography. She once again solidified her position in their second single, titled "Oide Shampoo", and recorded a solo song, which was included as a B-side on the single. This would be Nogizaka46's system during the group's early period. The 4th Single "Seifuku no Mannequin" would become her signature song. On 24 February 2014, it was announced at the AKB48 Group Team Shuffle that she would join AKB48's Team B.
On 26 February 2015, it was revealed that Ikoma will star in a live-action film based on the "Corpse Party" series of video games. Exactly a month later, on 26 March, it was announced that she would leave AKB48. On Nogizaka46's 12th Single "Taiyō Nokku" released on 22 July 2015, Ikoma returned as the group's center from her concurrent position in AKB48, last holding position zero on their 5th Single "Kimi no Na wa Kibō" two years prior.
On 21 February 2016, it was announced that she became a model for Anna Sui in Asian regions. She published her first solo photo book, "Kimi no Ashiato", on 24 February 2016. It sold 16,000 copies in its first week, and ranked 1st on the Oricon weekly photo book sales chart. On 29 March 2016, Ikoma participated in the ceremonial first pitch before a baseball match between The Fukuoka SoftBank Hawks and the Saitama Seibu Lions. She also appeared in SoftBank's advertising as the voice of "Giga-chan". In the same year, she reprised her lead role in the sequel to the "Corpse Party" film, "Corpse Party: Book of Shadows". The film was released in Japan in July 2016. Ikoma also appeared in a musical adaptation of "Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo" in September 2016.
On 31 January 2018, Ikoma announced her graduation from Nogizaka46 on the group's official blog. On 22 April, her graduation concert was held at the Nippon Budokan. Nogizaka46's 20th Single, "Synchronicity" was released on 25 April. It was the group's last single to feature Ikoma. After the revelation of her position at the middle of the second row caused a huge shock because the face of the group wasn't center for her own graduation as anticipated, amid reports, it was confirmed in her interview with Nikkan Sports that producer and songwriter Yasushi Akimoto expressed "Synchronicity" was for Ikoma to center, but she declined, for she didn't want the first single since winning the Grand Prix at the Japan Record Awards to be about her. Ikoma's graduation song and 1st Generation song, the B-side "Against" was the group's final song with her as their center, reuniting the front three with Erika Ikuta and Minami Hoshino for the first time since "Kimi no Na wa Kibō". She came up with the idea for the music video. On 6 May, Ikoma officially graduated from the group after an event at Makuhari Messe.
2018-present: Post-Nogizaka46.
