Tenshi-chan is a fictional character associated with Needy Girl Overdose, presented as a cute, angel-themed persona rather than a major independently developed character. The name suggests a playful, affectionate nickname style common in Japanese media, with "Tenshi" meaning angel and "-chan" adding a familiar, endearing tone. In the context of the series, the character functions more as part of the game's style, internet-culture aesthetic, and character branding than as a deeply explored narrative role.
