Sexy Demon Transformation!

My name is Ashiya Yamato. - I am a genius exorcist whose job is the cleansing of demons. - That's not something that can be revealed to the outside world, though, so no one knows about it. - With the spread of civilization, demons have been reduced in size, and are about as dangerous as bugs, - but I have containers in which I can collect them... because I have been disgraced! - She, Asuka, dared to snatch the position of Boss, greatest leader of the exorcists, away from the one - it should have belonged to - me! - No matter. I will recover what was stolen from me. - The possession abilities obtained from the demons, and the demon cleansing powers of the exorcists - - once combined, nothing is impossible! - That's right, with a myriad monsters under my command, I will have no trouble ravaging Asuka! - Once pregnant, her spiritual power will be reduced, and she will fall from the position of Boss!​
