Description
Asahi Rokka, performing under the stage name LOCK, is a second-year Haneoka Girls' High School student and guitarist for RAISE A SUILEN. A Gifu native, she relocated to Tokyo after earning a scholarship to Haneoka, drawn by its affordability and a transformative encounter with Poppin'Party’s performance at SPACE’s closing live—an experience that rekindled her musical ambitions.

Despite persistent academic and everyday challenges, Rokka found solace in guitar mastery, forming the middle school band TRICK with friends BERRY, PAT, and TRICK. The group disbanded following a farewell concert celebrating her Tokyo move, a decision her family initially opposed until her vow to excel in studies and domestic skills swayed her father. She now resides at her relatives’ Asahi Bathhouse and works part-time at Live House Galaxy, assisting event logistics.

Rokka sports slate blue hair in a low ponytail secured by a star-patterned scrunchie, complemented by leafy green eyes and thick black glasses. Onstage, she sheds both glasses and scrunchie, opting for a side plait. Her casual wardrobe features frilly floral dresses, green socks, and brown Mary Jane shoes, accented by a symbolic key necklace representing her hometown.

Shy and prone to stuttering, she occasionally reverts to her Gifu dialect when flustered or enthusiastic. Yet her quiet determination fuels relentless practice, balancing band commitments, work, and studies. She idolizes Poppin'Party, rivalling Mashiro Kurata in fervent fandom debates, and shares a steadfast bond with RAISE A SUILEN’s Masuki Satou (MASKING), relying on her during vulnerable moments.

Pivotal milestones include a celebrated solo performance at the Haneoka-Flowersawa joint festival, which caught Chiyu Tamade’s attention and secured her RAISE A SUILEN membership. A past onstage error stemming from nerves cemented her ritual of altering her appearance during shows. Her narrative arc sees her bolstering Poppin'Party’s spirits after public criticism, underscoring her rising impact in Tokyo’s music scene.

Born July 17 (blood type A), Rokka favors sweet bean paste and roasted sweet potatoes but avoids ramen shops due to discomfort with rushed meals. She maintains ties with her Gifu family and former bandmates, often humming enka melodies or Poppin'Party tunes while working.
