RCTD-746 Rie Miyagi, Yui Hatano

A mysterious gun that imbues souls transforms teachers and students into 'another self.' The user practices controlling these alter egos, leading to scenes of solo pleasure with a recorder, a striptease, and fellatio. Through soul possession, multiple individuals are simultaneously controlled. This leads to lesbian sex in the swimming club and changing room. Finally, even the beautiful school principal is controlled, resulting in a harem domination ending with cosplay.
