(This story takes before the chapter: A new threat from the book RWBY: The Crimson Squad/Revenge of Ridden's Zaku (RWBY X Male Reader))

In (Y/N)'s Dorm, his girlfriends asked him why did he do it. It turns out that he's avenging them.

Ruby: (Y/N), do you know why you think we're all presume dead.
(Y/N): Yeah, why?
Ruby: Allow us to explain.

(Flashback)

Team RWBY fought back against Salem's Inner Circles but they fell into the void one by one.

Meanwhile

They fell out of the void as Ruby landed in the sand and sat up while rubbing her head

Ruby: Ow, Where are we?
Yang: Sis, you okay?!
Ruby: Yeah, I'm okay.

Then Blake & Weiss appeared.

Weiss: You okay?
Yang: Yes we're okay.
Blake: Wait, Where's (Y/N)?

That's when they realize that they left him in the battle

Weiss: I hope (Y/N)'s alright.
Ruby: Yeah, Us too.

However (Y/N) wasn't alright, he became a Lieutenant Commander of the Red Army Forces. After 6 months they saw the TV and the Tape.

Ruby: Guys! There's a tape.
Blake: Play it.

Then she inserts the tape into the television then the screen starts.

(Y/N) (onscreen): Years ago, September 4th, 2354, a date which will live in infamy the Kingdom of Vale and Menagerie was suddenly and deliberately attacked by military forces of Atlas including its ally Salem Inner Circles. it's really obvious the planning to attack began many years ago, during the intervening time, the Atlesian Government has deliberately sought to deceive the Kingdom of Vale by faults statements and expressions of hope for continued peace, unfortunately for them, Team RWBY has fallen in Hands of Grimms included Inner Circles. I regret to tell you that Over 3000 Huntsmen and Huntresses including the civilians in the Kingdom of Vale have been lost. Atlas Invaded Menagerie years ago 2,089 Faunus people are lost, but no matter how long it would take us, To overcome this premeditated invasion. The Humans and Faunus in the righteous might will win to the absolute victory!

Then they clapped their hands.

(Y/N) (onscreen): Because of this unprovoked dastardly attack by Atlas, I asked to the Congress to declare a state of war.

Then Broadcast ends.

Then tape ended as they look in shock.

Ruby: (Y/N), What happened to you?
Yang: I don't know, He must have been thinking we're presumed dead.
Blake: He's been heartbroken for months
Weiss: and worse, out of grief.

Ruby had an idea

Ruby: We have to get back to our mainland.

She prepares a flare and fires in the sky when the ship appeared on the horizon and approaches them.

Ozpin: Hello, Team RWBY
RWBY: Professor Ozpin!
Ozpin: yes I am Alive and I have some company.

Then Glynda appeared

Glynda: Hello, students.
Ruby: Hello.
Blake: We have to get back to our mainland.
Ozpin: Sure.

They got on board the ship and departs from the island on the way to Harmony City.

(Flashback Ends)

Ruby: That's when we met your girlfriends from Azur Lane and Hanzo Academy.

(Flashback)

Enterprise and her friends were pinned down including His Squadmates: Aether & Tatsumi. They made what was supposed to be a contingency plan: Detonating themselves. Enterprise Called him through the comms and Asuka did the same.

Enterprise: (Y/N), we've been overrun and pinned down by Atlas. I know we want to spend time with you, I hate to say this. But that's not gonna happen right now. You have to stay strong, I knew you can do it.
Asuka: We're sorry, (Y/N). Stay strong.

That's when He realized that they made a contingency plan: detonating themselves.

(Y/N) *in comms*: Enterprise.
Enterprise: We love you, (Y/N). & I love you, (Y/N)-

Then Yang Strikes down with her fiery fist making them fly back and her comms is a bit cut as an explosion flying them back.

Yang: Hey, How's It Going.

Then Team RWBY came and help them and finally the Atlesian Army and their Bioweapons Grimm are neutralized.

Enterprise: Who are you four,

Ruby: I'm Ruby and This is my sister Yang and my Teammates: Blake, & This is Weiss. We're Team RWBY

Much to their shock that his childhood friends are alive.

Asuka: Wait, you're his childhood friends?!
Ruby: Yeah.
Zuikaku: But, He told us that he watched you 4 fall.
Ruby: Well, it's a long story.
Weiss: Short story: We found ourselves stranded on the island.
Kaga: Oh, I see.

Then Summer appeared along with Raven. Much to their shock.

Ruby: Mom, is that really you?
Summer: Ruby, Is it really you?
Ruby: Yes. Why
Summer: because I'm here now.

Ruby sprint towards her and hugged her with tears of joy.

Ruby: Mom, your Alive, I thought you were.
Summer: it's ok, my little rose. I'm here.

Then they look at Raven.

Raven: Team RWBY, I'm really sorry that I treated you as the enemy and called you weak, but when (Y/N) snapped at me, It made me realize that what I did was wrong. Please forgive me.

Then they felt sympathy finally said to her.

RWBY: We forgive you.

Much to her happiness

Raven: Thank You.

Then Raven asked their daughter about what happened to their father. He committed suicide due to his depression and she showed his farewell letter to them as proof.

Yang: Dad.
Ruby: Oh no.
Asuka: Do you know why he never have a chance to confess you four.
Ruby: What?
Weiss: Please do.
Blake: What is it?
Yang: What would that be?
Asuka: That He loved you four and said "I love you all"

Then Team RWBY blushed

Weiss: He loved us
Asuka: Yes, Here's the Harem List

Then she showed to them

Ruby: Wow, we can be with him.
Asuka: Yes but, We have to flee here
All: agreed

Then they left the battle scenes before the Search Party arrived.

(Flashback Ends)

Ruby: That's how we survived.
Yang: And don't forget we saw everything.

(Flashback)

They wore their cloaks and his 2 squadmates were in camouflage. They witness the Infiltration of Salem's Lair by Red Army Forces and The Remaining of the Crimson Squad. Destroying entire shipments and killing atlesian soldiers then one airlift is about to get away when suddenly.

(Y/N) *in Mobile Suit*: If I can't have it, NO ONE CAN!

Then He fired with Giant Bazooka but with Hyper beam. Destroying the one shipment. Much to their shock that their crush became aggressive. Then they saw Cinder, Emerald, & Neo are Arrested by the Soldiers and sent to the prison camp.

A few days later.

They went to their memorial but hidden in the trees then they saw (Y/N) walking and standing in front of the memorial as he thought that is final visit

(Y/N): hey guys it's me I don't know if I'm coming back or not but I promise you we will be together someday, but this is it, our last visit to you all. I love you guys. thank you for everything. Goodbye.

Then he left for his final mission.

Zuikaku: What?
Ruby: Our last visit, Oh no.
Weiss: What is it, Ruby?
Ruby: I think He and his army are about to launch a large offensive.
Weiss: What is it?
Ruby: your home, Atlas.

Much to her shock that Atlas might fall

Weiss: Then We have to get there Quick.
Ruby: Agreed.

Meanwhile in the Frigate.

After (Y/N) launched along with his army they encountered them

Neo: Wait, Girls!
Yang: Wow, I never expected that you can talk.
Willow: Daughter, is that
Weiss: Yes Mother.
Whitley: Thank goodness you're okay.
Weiss: Yeah, But we have to stop him
Cinder: Why

She told them everything that he continues to his conquest it will become worse and he's hurting himself.

Irina: Then we better get to him!
All: Right!

Then they took a Bullhead to reach a destination and saw Atlas were destroyed including mines and saw (Y/N) aiming at them.

Ruby: We see him!
Asuka: Let's go get him.

(Flashback Ends)

Yang: That's how we saw it about everything.

Then He was completely dumbfounded and realized that their presumed deaths were just a setup and he put his hand on his forehead & he was completely embarrassed.

(Y/N): Oh my Gosh, I didn't realize that.

Then his girlfriends laugh about his embarrassment.

Weiss: You're such a dunce.
(Y/N): Yeah, thanks for helping me out.
Girls: You're welcome!
Ruby: Group Hug!

Then they made a group hug as (Y/N) is finally able to control his emotions.
