Isekai de Ane ni Namae wo Ubawaremashita

Isekai de Ane ni Namae wo Ubawaremashita, which translates to 'My Name Was Stolen by My Sister in Another World,' originated as a Japanese web novel series serialized on the platform Shōsetsuka ni Narō. The narrative explores themes of identity and familial betrayal within the popular isekai genre, following a protagonist who suffers the loss of her name and status to a sibling. The work's focus on interpersonal psychological conflict distinguishes it from more action-oriented titles in the same category.

The subsequent manga adaptation, illustrated by Kotoko, serves as the definitive visual interpretation of the source material. Kotoko’s design approach emphasizes the dramatic tension inherent in the story, utilizing expressive character work to convey the isolation and frustration experienced by the protagonist. The manga has been recognized for its adherence to the darker, more introspective tone of the web novel, finding a dedicated audience among readers interested in the more nuanced or subversive entries within the isekai subgenre.
