Flashback

Issei, rias, and devin are inside what looks like a room full of chemistry sets.

Issei: Wh-What the hell is this?

Akeno: a research laboratory, it seems. According to the report, he was preforming a certain experiment here night after night.

Rias: documents that seem important will be sent to the demon world. The rest should be destroyed.

Flashback end

Devin: whatever the project is, we'll be ready

Then a small magic circle appear on the table then a holographic Grayfa appeared.

Issa: Grayfa!

Rias: So that stray demon was an alchemist who was working with goblins?

Grayfia: Yes, and we've discovered a related issue.

Rias: issue?

Grayfia: It seems he's synthesized a chimera from a carnivorous plant, Makamou and a dragon from the devil world released it in this town.

Asia: U-um like big brother's familiar?

Akeno: It's a monster made up of different creatures other then goat, dragon, lion and snake.

Devin: yeah meaning different species as one body.

Issei: M-Monster?

Bob: so that stray devil creation is huh?

Devin: yeah but I heard odd rumos from the pervs while they talk to issei.

Rias: About what?

Devin: At class, the 2 pervs said about something of girls who disappear from school. And don't remember a thing so.

Rias: IThe carnivorous plant aspect shouldn't be a big problem, but the dragon aspect will be a pain to deal with.

Issei: dragons ebody powers unique to those of demons or angles. I remember grayfa saying something like that.

Grayfia: That's it for now, I'll contact you again if there are any updates.

Rias: all right, thank you.

as the magic circle disappeared, kina, Alex and koneko came through the door.

Kina: president, we've returned.

Alex: yo.

Koneko: we're back.

Rias: (smile) good work. I can tell from your faces that you found something.

Kiba: yeah, we tracked it down. It's likely after the girls of this school.

Issei: girls?

Later at night

Everyone is out in the night looking for what kina and koneko found, John and rodrick along with Devin, Bob and Alex of their causal clothes

Issei: Then the rumor what Devin and Bob said is true, many girls suddenly got sick is…

John: so this stray devil expeft no one find out.

Rodrick: it's a lot effort whatever it is.

Rias: That's right. The problem is that we picked up traces of magic in those girls.

Issei: magic?!

Rias: It bothered me, so I had kina and koneko search in secret.

Alex: so what the bell the plant want with the girls anyway?

Then they saw a giant plant with a rose on the top.

Asia: Is it a plant goblin?

Rias: No, this is…

The rose open to reveal a gold color dragon head.

Issa: A Dragon?!

Devin: an ugly chimera there is

Alex: and it part Makamou

Bob: yeah I can senses it

Rias: this must be the one Grayfia was talking about. That saves me some trouble.

Then everyone spotted two girls walking with hypnotized eyes, it's murayama and katase in there pajamas.

Devin, John and rodrick the hell?

Issei: they're girls from the 3 boys and i class, Katase and Murayama.

Rodrick: by the tell of their eyes, the beast must save some hypnotic spell.

Alex: what it gonna do to those two?

The plant dragon then move his vines and morph them into flower-like things and they suck on there boobs as they moan.

Asia: I-It's moving.

Rias: It's sucking out their life energy.

Devin: (angry tick mark) you got to be fucking kidding.

Bob: bruh, for real?

Alex: it worst then that pervs bug.

Issei: how dare-

Rias: hold on issei.

Issei: But president.

Kina: Judging from past cases, it won't kill them.

Alex: who cares? This pervs chimera is asking to be turn to ash!

Bob: (sigh) first when those two girls are out, and then we cut some overgrown weed.

Devin: gladly

Rias: So let's wait and see for a bit.

Katase and Murayama turn to each other and then walk away into the forest.

Kina: they're unsteady, but they seem okay. It seems it put a spell on the targeted girls and made them come here every night.

Akeno: and it sucks out their life energy for nourishment?

Issei: I-Is that really possible?

Alex: now can we kill it?

Devin: yup.

Rias: in any case (confronting the beast) since we found it, it's luck is ran out.

As the chimera turn and looked at rias and the group, it attacks rias as she dogged it ben and the 3 boys along John and rodrick charged in. The destroyer and treasure Sniper start firing at the dragon the chimera roar try to hit them but they dodge it as so do issei.

Asia: issei!

Rias: Don't let your guard down. Commence attack! (cast her spell)

Akeno: okay, president! (change into her thunder priestess outfit and strike lightning at the vines)

Koneko: I'll kick its ass.

Kina: a threat to the peace of the school needs to be brought down! (slashing the vines down)

Alex: Let's do this. (use the guitar to destroy the vines)

Devin: Right behind ya! (use the holy gun to shoot at the vines)

Bob: right! (use the trumpet gun to blast the vines)

Issei: All right, here it goes! (bring out his boosted gear) Boosted gear!

As the plant dragon's vines made a shield to block issei attack as shocked as he dodge another vines attack.

Issei: This creature's pretty smart.

As koneko break the vines, kina slashing it more as the vines keep regenerate

Issei: there's no end to these!

Devin: this bastard won't call it quits!

Rias: It's full potential has been brought e air and soil of the human world, along with the life energy of the students must provide the optimal conditions for it.

Asia: Will everyone be all right?

Bob: Don't worry asia, everything be alright.

As the ground erupt vines around asia as she scream.

Bob: Asia!

As the vines got rias as well.

Devin: Rias!

John: look out!

As many vines got alex, devin, bob, john, Alex, rodrick and wrapped around there body except his head to put on a squeeze them tight so the plant keep them occupied. It even got akeno, koneko, and kina.

As the vines open flower mouth to suck Rias, Akeno, Koneko, Asia, and kina.

Rias: Wh-What is this?

Koneko: This again?

Akeno: Oh my, these tentacles are perverted!

Kina: n-no not there!

The boy's muffle angry since the vines cover their mouth.

Issei: Damn it! What shall we do?(as issei eyes wide seeing the girl's attire started to melt)

Akeno: Oh my, this is a problem.

Koneko: I don't like this slimy stuff.

Kina: My clothes!

Asia: Slippery stuff is eating away my clothes!

Rias: this slippery… slimy fluid… It seems to melt clothes!

Kina: Can't you use your powers to fight back?

Rias: I can't! I can't get my destruction spell to start!

Akeno: I can't generate lighting either.

Rias: koneko, can't you break free with your powers either?

Koneko: it's just too slippery.

Kin: I can't concentrate summon my sword!

Issek: At this rate...everyone will become naked! (a pervy smile)this quite...No, this is really big deal!

The boys hear issei as they swear they'll kill him next

Rias: Fight too!

Issei:(snapped out of his pervyness and activate his boosted gear)Dragon...

As the chimera let go asia and koneko the vines throw them.

Rias: Why did it only let asia and koneko go?

Akeno: I-It's focusing it's attacks on my boobs, it's extracting my life energy from them.

Kina: m-me too (moan) I can feel my nipples being suck.

Rias: w-what an indecent movement, no!

Issei: W-Wow! This is such a wonderful- I mean lewd- I mean, fearsome attack! It attach itself to woman's boobs and suck out their life energy!

Kina: but why breasts?

Issei: Don't ask the obvious! I too would love to glue myself to president , kina and akeno's b*** and suck out there life energy! (Raised his fist in glory)

Asia: Don't sympathize with the monster!

Issei: I'm not sympathizing, I'm hurting with jealousy right now! You damn chimera!

asia: that's no good either!

Kina: (moan)The girl who were reported sick all had plump chest.

Issei: (eyes wide)I see now! So this monster only preys on...big breasted girls!

Rias: D-Don't stand there in awe and do somethi-(moan)
