The news of All for One's death shocked everyone because they believed that he was invicible. Kamen Rider Genm as his killer shocked them even more after they confirmed that the killer was indeed Genm and because of this, Union put more effort to try to find him and capture him to find out about his secrets but still no results.

Union Academy

Ironwood: Damn it! All these efforts and we still got nothing! Just who the hell is Genm anyway?

(Timeskip)
???

Y/N is seen using Genm Level X-0 form raiding one of the hideouts of the notorious group Black Dogs who kidnap girls and women to rape them and make them their sex slaves. (A/N: Yes, the Black Dogs from Kuroinu is here, they're the only the Kuroinu characters that appear though)

One of their member tries to do a sneak attack on him but Y/N just nonchalantly avoids it and then he breaks his arm before he breaks his neck, killing him.

(Timeskip)

As he goes through their hideout he found their sex slaves and then get them out with the disguised shipgirls helping them to get out from this place before he goes back to maybe find something interesting there and his instuition was right, there are some interesting informations here. It turns out Issei has been working for them in exchange to have sex with their sex slaves. Another information is that this group have some plan to attack Azur Lane and make the shipgirls their sex slaves and Issei will also join them in the attack.

Enraged by what these lowlives planned to do to the shipgirls, Y/N angrily punches a table that conveniently in front of him and destroying it in one hit without saying a word and he then swears that he will make their leader, Vult, suffer.

Upon regaining his composure, he also finds the information regarding the locations of their other hideouts alongside with the location of their main hideout and he immediately goes to the other hideouts first with the disguised shipgirls coming with him before he goes to the main one but not without revealing the information about Issei's association with the Black Dogs to the whole world alongside with the pictures of him with the Black Dogs.

Black Dogs Main Hideout

After he's done with Black Dogs' other hideouts, Y/N is seen using Genm Level X-0 form is seen easily goes through any Black Dogs grunts without any trouble at all just like he did with the previous Black Dogs hideouts. One of them tries to attack him with his sword from behind but Y/N avoided that and forcefully takes his sword from his hand before he decapitates him with his own sword and after that he stabs another Black Dogs grunt that tries to attack him from the side in the head.

More Black Dogs grunt try to overwhelm him with numbers but Y/N skillfully uses the stolen sword until only one of them remain and tries to run away but Y/N throws the sword at left his leg which makes him fall as he tries to get away from Y/N.

Y/N approaches the last Black Dogs grunt as he begging him to spare his life but Y/N is having none of that as he won't let a single member of Black Dogs leave this place alive as he grabs his neck, and tears out his spine and skull. (A/N: Yes, Y/N just did the Spine Rip fatality on him)

(Timeskip)

Y/N is seen approaching Vult in his room.

Vult: Ah, Kamen Rider Genm, welco-

Y/N wastes no time and immediately socks him in the face and Vult tries to retaliate by punching him but Y/N simply grabs his hand and crush it which makes Vult yells in pain.

Vult: AAAHHH!!!

Before he grabs him and give him a knee strike to the face, after that, he breaks his left arm before throwing him away.

Vult: [struggles to get up] W-What the he-

Vult is struggling to get up as Y/N picks him up and continues his attacks by punching his stomach real hard before he slams his head to the nearest wall and then he gives him an uppercut which makes him flying across the room.

Vult: [tries to get up] Y-you b-basta-

Y/N interrupts him by kicking him in the balls.

Vult: AAAAHHHHHH!!!!

And he continues by ripping his broken left arm off.

Vult: AAAAHHHHHH!!!! WHAT THE FUCK?!!!

Y/N doesn't say anything and keeps his assault on him until Vult manages to back away when he has a chance.

Vult: W-wait! Please stop! I will give you anything! Women? Money? Anything!

Y/N: I want...your ears!

Says Y/N as he cuts Vult's ears with his fingers.

Vult: AAAAHHHH!!! MY EARS!!!

Before he rips off the shitty Guts wannabe's dick.

Vult: AAAAAAAAAAAAAAAAAAAHHHHHHHHHHH!!!!!!

And places it on his mouth.

He then forces him to chews on his own dick and then swallows it.

After forcing Vult to chew and swallow his own dick, Y/N then rips Vult's larynx out of his throat, then shoves it back into his mouth, letting Vult choke on his own blood as if he's not suffering enough already. (A/N: kinda like Mortal Kombat X Liu Kang's Sore Throat fatality)

(A/N: Kinda like this but Y/N is not pushing Vult with his finger)

He watches as Vult dies slowly in agony in front of him before leaving the place.

(Timeskip)

Issei is seen hiding as he is now a fugitive after Y/N revealed his association with the Black Dogs to everyone.

(Flashback)
Union Academy

Issei was seen entering the class and saw everyone there glaring at him which made him confused and then Rias started to speak.

Rias: Well, well, well, look who's arrived.

Koneko: I've always knew that there's something awful about him.

Issei: [tries to touch Rias' shoulder] What's wrong, babe?

Rias: [Slapped his hand away] Ugh! Stop talking to me like we're still a thing! How many times do I have to tell you that you're not my boyfriend anymore?! Anyway, as for your question. Everyone knows about what were you doing with the Black Dogs.

Issei: That's a lie! That's not true!

Rias: Oh yeah? Well, you can see them for yourself here!

Rias then showed him all information about his association with the Black Dogs that was revealed by Genm and also some pictures of him in one of Black Dogs hideouts that were also revealed by Genm.

Issei: H-how?

Rias: And after the truth about you working with those rapists was revealed, my brother and the other headmasters had no choice but to expel you and send you into jail and that means now I can finally kick you out of my Peerage.

Issei: You can't do this to me!

Rias: Oh, I can! Issei, as of now, you are no longer part of my Peerage.

Issei then screamed in pain as his Evil Pieces came out of his body and into Rias' hand.

Rias: I should have never revived you.

Issei: NO! This can't be happening!

Before he can do anything, he got beaten up the other Peerage members who also quite disgusted by him.

(Timeskip)

After that, the police arrived to arrest Issei. The police car that transported Issei to the jail had an accident and he took advantage of this to escape. Unfortunately for him, Y/N who heard about the accident found him and decided to follow him until he's completely alone.

(Present)

As Issei is hiding in a abandoned warehouse, he takes this moment to rest for a bit. Not realizing that Y/N is following him.

Issei: Damnit! Everything has gone to shit! I heard that Vult is dead and Black Dogs is finished, that means I lost my chance get those hot Azur Lane's shipgirls and make them my harem and my sex slaves now that the Black Dogs attack on Azur Lane is obviously cancelled.

Hearing the comment about what Issei wants to do to Azur Lane shipgirls makes Y/N who is using Genm Level X-0 form who's hidden from his sight decides that it is the right time to appears out of nowhere (from Issei's point of view) (Y/N also made sure there was no one else near the warehouse) before attacking him which caught Issei's off guard before he blocks and dodges Y/N's attacks until Y/N sees an opportunity and summons Gashacon Breaker Blade Mode and cuts Issei's left arm off with it.

Issei: AAAAHHHHH!!!!

Y/N then de-summon the Gashacon Breaker and starts repeatedly punching him in the face before he kicks him which pushes Issei a bit and then he does a split and punches him so hard in the nuts.

Issei: AAAAHHHHHH!!!

Before he stands up and continues his attacks by giving him a roundhouse kick which launches him across the room. He then summons the Gashacon Breaker again and stabs the lying Issei at his right hand with it.

Issei: AAAAHHHHHH!!!!

Y/N: Hey, you want to see something cool?

Issei: W-what?

Issei watches as Genm reverts back to Y/N.

Y/N: Ta-da!

Issei: No... It can't be true, you're Genm? No way I got my ass kicked by you of all people!

Y/N: Oh, it is true. I'm also the one who revealed your dirty little secrets to everyone.

Issei: WHAT!? SO YOU'RE THE ONE WHO RUINED MY LIFE!? YOU FUCKING SON OF A BITCH!! I LOST MY HAREM BECAUSE OF YOU!!

Y/N: Bruh, your "harem" already hate your guts even before I revealed your secrets. Rias actually wanted to kick you from her Peerage even before I revealed what you were doing with the Black Dogs but her brother won't allow it until recently.

Issei: No! You're lying! Rias loves me! She always do!

Y/N: Rias was right, you really are delusional. She told me that she broke up with you months ago and despite that, you keep insisted that you're both still lovers. Anyway, how about a fun fact? Did you know that I'm actually the commander of Azur Lane?

Issei: WHAT?!? HOW?!? NO FUCKING WAY YOU'RE THEIR COMMANDER?!

Y/N: Yes way. Deny it all you want, but it's true. Oh, and also, most of the shipgirls except the little girls are my girlfriends and let's just say that I don't like what you and your Black Dogs friends planned to do to my girlfriends and other shipgirls.

Issei: SHUT UP!! SHUT THE FUCK UP! YOU FUCKING LYING! HOW THE FUCK A POWERLESS LOSER LIKE YOU GET A HAREM OF THOSE HOT SHIPGIRLS?!? I WILL FUCK THEM IN FRONT OF YOU!! YOU HEAR ME, LOSER!!!

Y/N: HAHAHAHAHA!!! And how are you gonna do that? Hmm? You lost your left arm and your right hand is now useless thanks to me. Oh man, this is so priceless! Oh yeah, one more thing, Me, alongside with some disguised shipgirls are also the ones who killed all of the Black Dogs with their leader, Vult, died like a bitch and you would share the same fate as them.

Y/N then pulls his Gashacon Breaker from Issei's right hand and impales his dick with it.

Issei: AAAAAAAAAAAAAAAAAAAHHHHHHHHHHH!!!!!

Before he starts splitting Issei in half vertically, from the groin to the head, slowly, to make sure that Issei feels excrutiating pain before he dies.

After killing Issei, Y/N transforms back into Kamen Rider Genm Level X-0 (just in case) and leaves the warehouse.

(Timeskip)
Azur Lane HQ

After he's done with the Black Dogs and Issei, he then spends some time with his shipgirls as he already done with the paperworks. He then feels his phone ringing in his pocket and checks it out.

Y/N: Oh, it's from Rias.

Crimson Princess
Hello, Y/N.

Y/N
Hey, Rias.

Crimson Princess
Did you hear the news about Issei working with the Black Dogs?

Y/N
Yeah, I did. Man, What a scumbag, I didn't know that good for nothing pervert would work with those rapists.

Crimson Princess
Me neither, I heard someone killed him after the car that transported him to jail crashed and he tried used that opportunity to escape.

Y/N
At least he died before he can do something horrible to other women.

Crimson Princess
Yeah, anyway, what about your job as a commander of Azur Lane? How are you doing over there?

Y/N
Oh, I'm doing good, thanks for asking. How about the others?

Crimson Princess
They're doing well.

They then keep chatting for a bit.

(Timeskip)
Beach

Y/N is seen relaxing in the beach as he sees Littorio and Vittorio Veneto approaching him.

Y/N: Oh hey, girls. Can I help you?

Littorio: Oh, there is something you can do for us~ Isn't that right, Vittorio?

Vittorio: Y-yeah.

Y/N: Hm?

(Timeskip)
(Lemon scene incoming)

Y/N, Vittorio, and Littorio are seen having some fun in a private place as Y/N now is seen thrusting at Vittorio in doggy style position while fingering Littorio's pussy.

Vittorio: [moans] Oh yes! It feels amazing! Faster, Y/N! Faster!

Littorio: [moans] You really know how to please a woman with those fingers.

They keep at it for several minutes until they cum.

They then change position as Littorio now is seen riding Y/N's dick while he's licking Vittorio's pussy.

Littorio: [moans] You're so big, Y/N. This feels so divine~

Vittorio: [moans] His tongue feels so great as well~

Littorio then moves faster while Y/N licks Vittorio even harder until they cum several minutes later.

They're not done yet however as their fun about to last for hours.

(Lemon scene ended)

Then the screen goes black.

SEE YOU NEXT GAME

(A/N: To be honest with you, I don't actually hate Issei, well, the CANON one anyways. Issei in most of Union Academy stories is a different story, there are actually some good Issei in some Union stories but they are quite rare, at least to me anyway)

(A/N: Anyway, here's some bnuuy pictures and some other stuff I that found)
