Juskiss (1996)

Original title: ジャスキス ＪＵＳＫＩＳＳ

Space Investigator Justy arrives on Earth in pursuit of a dangerous bio-weapon, Debora, which has the ability to attach to living things and to control their consciousness and pass on to others through bodily contact. The only way to capture Debora is with a kiss, so Justy commandeers the body of a young man, Masayoshi, and has him kiss any person she suspects of being possessed by Debora.
