Yuzuki Watase

Yuzuki Watase is a Japanese voice actress and musician, best known as the rhythm guitarist for the band Ave Mujica within the BanG Dream! franchise. Under the stage persona Mortis, she voices Mutsumi Wakaba, a character central to the group's darker narrative arc. Watase is also recognized for her earlier role as Miiko Takeshita in Bushiroad's D4DJ franchise, where she performed as part of the unit Lyrical Lily. Affiliated with the agency Hibiki, she has built a career that bridges voice acting and live musical performance, gaining a dedicated following in the anime and seiyū community. Her work with Ave Mujica, known for its intense, theatrical style and intricate storytelling, has made her a standout figure in the franchise's ensemble cast.[edit]

Born on February 18, 2003, in Japan, Yuzuki Watase grew up immersed in anime and music, which led her to pursue voice acting. She trained at a voice acting school before being scouted by the agency Hibiki. Her first professional role came in 2020 when she voiced Miiko Takeshita in the D4DJ franchise, part of the unit Lyrical Lily. This role required her to not only voice the character but also perform live as a singer and dancer, giving her early experience in the multimedia idol industry. The D4DJ project was a major stepping stone, exposing her to the demands of franchise-based performance and helping her build a fanbase before her next big opportunity.[edit]

In 2021, Watase joined the BanG Dream! franchise as Mutsumi Wakaba, the rhythm guitarist of the newly formed band Ave Mujica. The band's debut single, released later that year, introduced a darker, more dramatic sound compared to other BanG Dream! groups, and Watase's role as Mortis, a stage persona with a haunting, theatrical presence, quickly became a fan favorite. She performed at major events like BanG Dream! 11th LIVE, contributing to the band's growing discography, which includes singles such as "Ave Mujica" and "Imprisoned XII." Watase also appeared in the anime series BanG Dream! It's MyGO!!!!! and the upcoming Ave Mujica anime, further expanding her reach. Beyond Ave Mujica, she continues voice acting in other projects, balancing studio work with live performances that showcase her guitar skills.[edit]

Watase's public image is closely tied to her role as Mortis, a character known for her enigmatic and intense stage presence. Offstage, she presents as warm and approachable, often sharing behind-the-scenes moments and personal interests on X and Instagram. Her social media voice is a mix of professional updates and casual, relatable posts, like photos of her cat or matcha lattes, which endear her to fans. The BanG Dream! fandom, known as "BanG Dreamers," has embraced her as a key part of Ave Mujica's appeal, and her live performances draw praise for their emotional depth.[edit]

Yuzuki Watase has cultivated a devoted following that bridges the gap between the *BanG Dream!* franchise community and the specific allure of her alter ego, Mortis. While the broader fanbase often identifies simply as "Bang Dreamers" or aligns with the collective identity of the band Ave Mujica, there is no single, officially documented name for a fandom dedicated solely to her individual persona. Her audience is defined by a shared appreciation for her dual life as a rhythm guitarist who taught herself the instrument specifically for live performance and as the voice behind the enigmatic Mutsumi Wakaba. Fans frequently engage with her casual social media presence, bonding over her love for matcha desserts and her pet cat Mugi, yet these interactions remain part of a general, enthusiastic following rather than a structured organization with unique rituals or named campaigns. The narrative surrounding her work is deeply tied to the fictional lore of Ave Mujica and its theatrical releases, such as the anime series that premiered in January 2025 and concluded in March 2025, alongside the upcoming film *Ave Mujica prima aurora*. Despite her central role in this high-profile project, iFANN's Global Fame Engine has evaluated Yuzuki Watase but currently does not place her in the published rankings for the Global Top 1,000 or any Top-100 scope list.[edit]

Watase adopted the stage name Mortis for Ave Mujica, a Latin term meaning "death" that perfectly encapsulates the band's gothic aesthetic. She is entirely self-taught on the rhythm guitar, dedicating daily practice sessions to mastering the complex arrangements required for their intense live shows. A known enthusiast of horror cinema, she credits these films with helping her channel the darker emotional tones necessary for portraying Mortis. Her personal interests often spill into her public posts, where she frequently shares photos of her favorite matcha desserts and her pet cat, Mugi (short for Mugwort). Although the *Ave Mujica* project has generated significant discussion regarding its plot twists and musical achievements, no specific viral legends or extraordinary crowd incidents involving Watase personally have been documented in available records. The focus remains on the band's collective milestones, such as the release of their debut mini-album *Alea jacta est* and their successful transition from anime to live events.[edit]

Watase keeps her family life private, rarely discussing her parents or siblings in interviews. She has mentioned in passing that her parents were supportive of her voice acting dreams from a young age, driving her to auditions in Tokyo. She currently lives alone in an apartment near her agency's studio, sharing occasional glimpses of her space on social media.[edit]

Within the BanG Dream! franchise, Watase works closely with fellow Ave Mujica voice actresses Riko Fukui (Tsumugi Momono/Tsukuyomi), Yuu Shimamura (Tomori Takamatsu/Oryo), and Aina Aiba (Tama Hazawa/Nyx). She also maintains connections with the D4DJ cast, including members of Lyrical Lily.[edit]

Yuzuki Watase has kept her romantic life entirely private. As of 2026, there are no public records or credible reports of her dating anyone. She has not discussed relationships in interviews, and her agency does not comment on her personal life. Her current relationship status is considered single.[edit]

Per iFANN's editorial analysis, Yuzuki Watase's net worth is estimated at $1 Million as of 2026. This financial standing is built upon a diverse portfolio of income streams, including contracts for voice acting roles across major franchises like *BanG Dream!* and *D4DJ*, as well as earnings from live performances with the band Ave Mujica. Revenue also flows through merchandise royalties associated with the *BanG Dream!* universe and various endorsements. Additionally, she generates income through appearances at anime conventions, leveraging her popularity within the seiyū community. While exact figures remain private, her consistent work with prominent entertainment projects suggests a stable and growing financial trajectory.[edit]
