(Y/N is seen piloting the SSD as he forcefully leaves his mother after he finds out she was also mentally insane.)
(Meanwhile at I.S. Academy, the students heard the new about the SSD.)
Chifuyu: (to her fellow pilots) You know what to do!
I.S. Pilot: Yes, ma'am.
(Meanwhile inside the hangar, Natsuki Hagiwara, Kouta Ochiai, Takajou Mamoru, Theresa, Reiji Kurose, Nagi Aoe, School Days girls, and even the all 800 yandere girls already sneaked inside the spaceship.)
Natsuki: How big...
Kouta: It doesn't look like a ship outside, but it's indoors prove us wrong.
Makoto: This thing can't even fly, according to square cube law.
Taihou: (stern) Hello, this thing has an extremely advanced technology.
Theresa: Who built it anyway?
Reiji: How did someone bury it?
Nagi: And how did it remain intact?
(Meanwhile in his room, Y/N is seen with so many questions in his mind.)
Y/N: (in mind) Who could ever have built such gigantic thing and all vehicles inside? Well, it doesn't matter. Now I don't need to spend money to travel to space.
(Y/N then tries to drive the SSD underwater, and much to his surprise, it gets unhindered.)
Y/N: WHOOOOOOOOO!
(Flashback)
(Y/N's father is seen abusing his own coworkers and bullies alike.)
F/N: WHO DO YOU GUYS THINK YOU ARE? MY BOSSES? NO, YOU'RE NOT! LEARN THIS LESSON, PUSSIES!
(Some moments later, Y/N's father is seen ganged up and killed by several men.)
Man 1: One less jerk to deal with!
Man 2: Yeah, he deserved it.
(Flashback ends)
(Y/N remembers that his mother had a crush on him ever since he was a child.)
Y/N: (in mind) Did mom really plan dad's death?
(Y/N didn't think much because he was enjoying the trip. Suddenly he hears a sound.)
Y/N: (stern) What was that?
(Back to the others, Makoto is seen dead because he got accidentally crushed by a hanging TIE bomber.)
Kotonoha: Finally, this playboy is dead!
(Then Y/N comes in and sighs in annoyance.)
Y/N: You sure are persistent.
M/N: You bet we are, son.
(Then Y/N teaches some of the girls how to operate the vehicles, but gives them a warning.)
Y/N: Those vehicles can only be operated by me. So don't mess with them!
Akagi: How do you fly this spaceship then?
Y/N: Well, there are some buttons which control the navigation, and others who control the engines. I'll only teach you those!
Enterprise: You're being mean.
Hood: Yeah, that's why we demand you to pat our heads.
Y/N: (groans) Fine...
(Y/N then reluctantly pats Enterprise, Hood, FDG, Prince of Wales, Dido, Kaga, Amagi and Yamashiro. The last one then makes another demand.)
Yamashiro: Now rub and kiss my nose!
Taihou: Mine too!
(Y/N sighs in annoyance as he reluctantly rubs and kisses the two girls' noses.)
(Meanwhile, the monsters had completely destroy several cities and reduced it to rubble and fires everywhere. Most of citizens died but luckily a mysterious person captured all of the monsters present there without any issue.)
(Back to the SSD, Y/N manages to find a way to return to his home dimension with it, and lands it in the middle of the forest.)
Y/N: Hehe. This is fun.
(Y/N then decides to use his TX-130 tank with it being upgraded with more firepower, more shield, much faster than even Lambo, much tougher armory and the hover tank can float about 7 meters above the ground while speeding.)
Ruby: How did he do this?
Weiss: What are so much upgrades for?
Blake/Yang: We don't know...
(While driving his TX-130, Y/N sees a group of guys who happened to be Tomaru's associates and they too owned some PMC's.)
Y/N: So they think they can stand up to me, huh? Alright, time to put those wimps in their place!
(He shoots them all with the quad cannons rapid fire blasters.)
Y/N: There's no one who can stop me! NO ONE!
(He goes to the middle of the city, unaware that his bullies are ready to fight him.)
B/N 1: HEY, ASSHOLE!
Y/N: Huh?
B/N 1: EAT THIS!
(The bullies shoot Y/N's tank, but the shots only scratch the painting.)
Y/N: Nice try, losers. Now it's MY turn!
(He decides to terrorize the bullies while the girls simply laugh maniacally. He chases them everywhere. In the alleyway...)
Y/N: Nowhere to run!
(In the school grounds, breaking through the fence by ramming it and scaring all of the students present and teachers alike.)
Y/N: Nowhere to hide!
(In the amusement park...)
Visitor 1: Look, a battle tank!
Y/N: Don't touch that!
Visitor 2: Who said that!
Y/N: I did.
(Y/N then shows that his TX-130 tank is real, scaring the people before resuming his chase on his bullies.)
(And in a mansion, where he shoots all of them and also shoots several furnitures inside including the statues, stairs, basement, etc. The mansion collapses with so much destruction, but Y/n activates a giant shockwave blast to clear them off.)
Y/N: Well, I guess they learned their lesson... or did they? Whatever... they're dead anyway.
(Meanwhile, the girls are seen in their own vehicles as they go on a killing spree and butch anyone they come across, except for children.)
(Timeskip)
(After Y/N was done, he decides to make a decision.)
(Ending 1)
(Y/N tries to run away, but gets captured by the girls, who then rape him, especially in his ass as he screams in agony, much for the girls' sadistic pleasure.)
Girls: HAHAHAHAHAHA! THAT'S RIGHT! SCREAM FOR US!
(Ending 2)
Y/N: Fuck this shit, I'm out.
(Y/N manages to escape, but he didn't have much peace for much longer, because the girls were waiting for him and struck at the right moment.)
Yor: You should have learned to not abandon us.
Glynda: You need more punishment!
(The girls start laughing maniacally.)
(Ending 3)
Y/N: Well, if you can't beat the enemy, join him.
(Y/N marries all of them while secretly turning them against the world, and eventually sending them on a suicide mission. Unfortunately for him, the girls somehow survived.)
Yor: (angry) That's it...
Raven: We'll teach him a lesson he'll never forget!
Yang: And we'll do it with a YANG!
(Some girls groan for Yang's awful pun, but they prepare to settle their score with Y/N.)
