Ruka Inui, a homebody who awakened a dark personality (obsessive woman) due to her excessive addiction to card games. (FTHTD-234)

Normally a gloomy, homebody girl, but in card game battles, she's dominated by her darker personality, transforming into a sadistic, horny beauty. She initiates sex duels with regulars at the card shop, playing with their penises until their semen (life points) are completely drained! Finally, she induces ejaculation with unprotected penetration deep into their uterus! A forbidden, frenzied sex game!
