Drain Plant

Monsterpedia Entry
''"An artificial monster created to hold men inside her, endlessly draining their semen. This is a mass-produced variant based on a prototype for enlarging the womb to hold the extraction specimen. At some point, the genes were crossed with an angel’s. Imbued with intelligence and a will, she is able to monitor and care for the subject inside her. They act as their own security, catching any specimens who escape.

Just like a mother caring for a baby, they supply the internal specimen with nutrients through a tube. They then force the male to ejaculate continually to harvest semen. Once taken inside, most men become crippled in around an hour, unable to do anything but come.

In addition, she is able to use harvested semen to fertilize eggs in an efficient manner."''

Battle Overview
Just simply use the Daystar/Salamander combo, you won't have much to worry about. Use Alice if the heat gets turned up.

Evaluation
''“Remodeling a divine angel into that thing… I wish to tear both the plant and the one inside it to pieces right now… Always have Gnome available due to her restraint. Other than that, there’s nothing of note. Now go, oh brave Luka. If you enter that monster again, I will smite you both.”''
