We have to fight to survive (Highschool DxD X Kamen Rider Amazon Oc)

Final Episode: The one to kill and the one to protect

As it continues raining and as the drones kept flying releasing the pesticides causing multiple Amazons dying awakened or not as Irina, Kazuya, Harmamo were still in the rain and that was when Kazuya noticed Mamoru crying still his arms cover in blood from eating Misaki's arm

Kazuya: "Hey Mamoru!" He went up to him as Irina followed

Mamoru: "STAY BACK!" He was crying uncontrollably

Kazuya: "Mamoru come on we gotta get out of here!"

Mamoru: "No... just let me die I can't live with the burden that I already caused..."

Kazuya: "Look it was just one time! I'm sure Misaki will forgive you! We will get through this together!" Then they all notice the drones above them

Harmamo: "GUYS WE GOTTA GET OUT OF HERE!" Then Kazuya nodded as he, Mamoru, and Harmamo hoped on Kazuya's Junglaider

Kazuya: "Irina... sorry but please don't get sad but i'll be gone for a long time." 

Irina: "Wait. Take this." Then she handed him a sword "It's the excalibur of mimicry." Then the sword started to take shape of how Kazuya desired which became a white fingerless glove that fits on his right hand

Kazuya: "Thank you." Then she started crying "I promise when I come back I promise to be with you." Then they all drive away as it continues raining and as more an more Amazons were dying out

3 weeks later

As it was a clear weather things went a bit normal as Kazuya, Sho, and Harmamo didn't attended school as the Gremory household were trying to deal with the death of Issei. The extermination squad were disbanded but later on they were all reformed for some money again as they went to find and exterminate the remaining Amazons and to find Kazuya and Harmamo as they were at a beach

Shido: "Alright you all understand what to do?"

Takai: "Yeah find Kazuya, Harmamo, and Mamoru and eliminate the remaining surviving Amazons." Then they got out of the van as they were ambushed by some Amazons as they fight back and they continue fighting but it wasn't enough as they outnumbered them

Misaki: "Crap this isn't working!"

Shido: "We can't give up!" Then that was when they all go after them until three of the Amazons were on the ground "What the?!"

That was when they see who did it. An Amazon with a green body and red eyes, the one they knew, Kazuya Wilda

Shido: "Kazuya?" Then the other Amazons that were about to kill the extermination squad changed their target on Kazuya

Kazuya: "I'm sorry...please forgive me. Boosted gear." Then he summons his boosted gear as he used the excalibur of Mimicry as morphed it to a attachable blade on his arm

Boost!

Then he starts attack as every one of them surrounded him

Boost! Boost! Boost! Boost! Boost! Boost! Boost! Boost! Boost!

Kazuya: "..." Then he transfers all the power to the blade

Transfer!

Then with one swipe in a 360 motion he managed to kill the Amazons that surrounded him

Misaki: "Shit he's badass." Then Kazuya took off his driver and revert to normal as the blade turned back to a white fingerless glove

Kazuya: "Hey guys."

Shido: "Looks like you're under control. Come back chief's order."

Kazuya: "...No."

Shido: "Huh?"
