One of her most discussed mainstream-adjacent projects was the 2016 tokusatsu-inspired release, 巨大女神グランレディー (Giant Goddess Grand Lady), which appealed to fans of giantess and special effects media.

In 2021, the marketing of AV stars became increasingly personalized. Social media platforms like Twitter became essential tools for self-promotion, allowing Saejima to bypass traditional studio PR and communicate directly with fans. This direct line of communication allowed her to market her specific "events" (online meet-and-greets and signed merchandise sales), which became a financial lifeline during periods where filming was halted or restricted. Saejima utilized these platforms to showcase her daily life, fitness routines, and off-screen personality, transforming from a distant image on a DVD cover into a tangible, accessible figure. This digital sovereignty allowed her to maintain relevance even without a constant stream of new physical releases.
