Species 4: Everyday Life with a Slime

The 4th episode in the series, it introduces the 4th girl to live with Kurusu, Suu.

Plot
The episode starts with Miia staring dreamily into space, thinking about Kurusu's proposal to date her a potential marriage candidate(albeit in a way that was drastically different to how he really suggested it), before writhing in delight at the thought. We then get a shot at a strange, slime like liquid, before cutting to, Centorea who is in a similar state to Miia, shining her sword and quietly saying "Marriage, huh?". Quickly snapping out of the state, her thoughts are interrupted by Papi who asks her to play a game with her. Centorea refuses saying she needs to polish her sword. We get another shot of the mysterious green goo and then Kurusu states that dinner is ready. Papi asks Kurusa to play a game with her to which he simply says "After dinner, Papi", after which she drags him into the living room saying "Hurry, hurry". Miia checks the cooking pot to find to green goo inside, which quickly attaches to her face causing her to pass out.

After the opening, we find Kurusu nursing Miia after she passed out from suffocation, and Centorea reveals that what attacked her was a slime. Kurusu is surprised as he didn't know such things existed, but Centorea says that slimes are just one of many species that human society doesn't recognize. Centorea tells him not to worry however, saying that she won't allow the slime to harm him. Papi butts in asking Kurusu to play a game with her but Centorea scolds her saying there is no time for games. The slime reappears and Centorea attempts to cut it in half but is surprised to find her sword has no effect, as she thought that slimes were supposed to be the weak ones in RPG's. They both end up getting covered in slime and Centorea ends up in a very lewd looking state, so Kurusu bolts towards to bathroom in order to wash himself off. While he is thinking of a solution to their "slime problem", Centorea knocks on the door and simply says "Would it be okay if I...". Kurusu says yes unwittingly inviting her into the bathroom with him. She walks in completely naked much to Kurusu's surprise, and she unwittingly slips, falling over and trapping him underneath her breasts. She says that she can't get all of the slime off herself and so Kurusu washes her backside as she cannot reach there herself. When he asks her what she usually does when she needs to wash back there, he unwittingly cleans around her "rump", an erogenous and sensitive area. Flustered and babbling, he exclaims that he will just wash somewhere else,, and so moves onto her breasts, all the while a silhouette appears on the glass door. He says that he just panicked and the both of them give up on washing Centorea. Trying to change the subject, he says, "I wonder why the slime attacked us?". Centorea answers, saying is was probably looking for water. Kurusu then says, that it would "be dangerous to let it in the bath then, aha", before the slime appears above them and the water. Centorea on reflex tries drawing her sword, but instead reaches for Kurusu's penis instead, grabbing it while he screams "that's not your sword!". Taking a few seconds to sink in, centorea simply looks at her hand before screaming and falling over, hitting her head and falling unconscious.

The slime grabs Kurusu while he struggles, thinking he is going to be eaten, but it then miraculously transforms into a a beautiful and curvy female form. She follows by washing him in the same way he washes Centorea, rubbing him down with her breasts and scrubbing him down with a brush. Kurusu realises that she is trying to communicate by copying everyones actions, and is lulled into thinking she isn't that dangerous. Almost immediately after though, she squeezes Kurusu between her cleavage absorbing his entire head into her body, suffocating him.
