Baptism of Blood aka Senrei (1996) - Kenichi Yashihara.

Stricken with a disfiguring malaise, TV icon Izumi Wakakusa (Mie Yoshida)undertakes a cruel treatment, using the alien methodology of nefarious Dr. Meredith (Tatsuya Go), which, in essence, mortally hijacks the delectable body of her nubile daughter Sakura (Rie Imamura). Once poor Sakura gets wind of her mother's ultimate treachery, the delightfully skewed narrative escalates with a demented Cat III zeal, in exhilaratingly warped Baptism of Blood! The ailing mother is delightfully monstrous, ravenously covetous of her beautiful young daughter's lustrous complexion, and lissom body, utterly ruthless in her desire to transplant her brain into her daughter's pretty head!

Gruesome, melodramatic, sinisterly surreal, and altogether bizarre, the Neo-Gothic shocker Baptism of Blood is an often blackly funny, sublimely inventive, thrillingly nuts J-Horror treat! The truly excruciating, and exquisitely prolonged brain extraction procedure remains a macabre masterclass in H.R Giger-inflected steampunk splatter! Based on a story by Japanese Horror maestro Kazuo Umezo, his winningly off-centre shocker Baptism of Blood remains a madly compelling, uniquely strange J-Horror confection, generously layered with far richer ingredients than blandly remade, dully recycled mainscream British/U.S horror fare.
