Akaki Chikai (赤き誓い)

Akaki Chikai (赤き誓い) is a Japanese group credited under both its romanized name and Japanese title. It 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 act a fixed identity across artist databases and anime music catalogs. For listeners searching anime-related credits, the dual-language name and stable roster are the most useful identifiers. That makes Akaki Chikai easy to recognize as a defined ensemble rather than a loose project name.
