Marin is a rising BBW actress who's quickly becoming a sensation in the industry with her voluptuous curves, sun-kissed blonde hair, striking purple eyes, and fearless confidence. As the latest (and curviest) member of Misaki's exclusive BBW harem, she brings that signature gyaru energy: loud, bubbly, super flirty, and always ready to party or tease. She's unapologetically thick, loves showing off her body in skimpy outfits like patterned swimsuits and chokers, and has a playful sassy vibe.

The Fatass BBW Officer who saved The Nyakumi World

Name: Komi Shuuko
Age: Late 30s (but shhh—she says 29)
Appearance: A full-figured, confidently plush actress with curves that dominate every frame she’s in. Her signature outfit? Stretchy lounge sets that just barely contain her glory. Hair always perfectly coiffed, lips always glossy—even if she’s just lounging and eating sushi offscreen.

Nyakumi’s favorite fatass BBW voluptuous star.

Name: Emi
Age: Late 30s (but won’t admit it)
Appearance: A former heavyweight with lingering curves. Her resting scowl is undercut by rosy cheeks and the occasional nervous giggle—especially when Misaki walks in.
Personality: Tries desperately to play the grizzled toughie ("I bench-pressed regrets!"), but one compliment about her dimples reduces her to flustered mush. Secretly pines for Misaki while aggressively wingman-ing for Akeno (it’s complicated).

Name: Makima
Age: Technically decades old (but "eternally 30" for dignity).
