Experimental Organism A-3 is an artificial chimeric monster that attacks Luka while he was pursuing Promestein after she was released from stasis and thirst overcomes her. Having no “real name” except for a serial number, it is one of Promestein's experiments, contained within her hidden laboratory under Remina.

Much to Luka's shock and horror, she claims to be a former angel that was experimented upon, despite being her ally.

Monsterpedia Entry

“A Chimeric Beast created in Promestein’s laboratory, composed of variety of organs from both monsters and angel. She was the result of early experiments of direct transplant of monster organs into the body of an angel. No good practical use was found for her, and she was simply kept in the tanks until now. Due to the primitive nature of the transplantation, it seems to have deeply impacted her memories and emotions. Her entire being seems to have degraded, and seeks to greedily devour male semen like a common monster.

Lastly, the angel used for this experiment was said to have offered into it due to having non-punishment sexual relationship with humans.”

Battle Overview

Like previous battles, simply bum rush her with Death Sword Chaos Star and meditate when necessary. Watch out for Immoral Blowjob Preparation and Guard it to avoid Immoral Feeling which is a one-hit KO. Her bind requires 3 turns of Struggling to escape.

If Luka loses, A-3 wraps him up in her tentacles and gives him a blowjob, later sticking one of her tentacles into his anus for further stimulation, and he is squeezed dry to his death. If Luka is defeated by Immoral Feeling, her attacks will continue on to the losing scene.


“Squeezed to death by that failure of an angel… You yourself are like an experiment organism, aren’t you? Your tactics are still limited at this moment. Just fight carefully, keeping an eye on your health. But watch out if she prepares a move… If you don’t guard it, you will surely lose. In addition, if you lose to a certain move, she’ll continue violating you even after your loss… Now go, oh brave Luka. An ugly angel like that is not needed. Dispose of her.”


  • If Requested, Immoral Feeling can immediately be used and does not require Immoral Blowjob Preparation beforehand.
