Akaki Chikai (赤き誓い) is a Japanese group credited under both its romanized name and Japanese title. The act is listed as a four-member lineup made up of マイル, ポーリン, メーヴィス, and レーナ, giving the group a clear and fixed identity from the start.
With that bilingual naming, Akaki Chikai stands out as a defined Japanese ensemble rather than a loose project name. Its main publicly available identifiers are the dual-language credit and the member roster, which are the details listeners are most likely to use when looking it up in anime music catalogs and artist databases.
