Let's focus on Yumi for some time here because we need to have some focus with the gessen girls academy here.(let us begin the chapter but there will be some new people coming from specific anime you have watch before)

November 1st
Upon exiting the hotel
Yumi: Babe my team is  going out to go get some groceries we might be out for awhile
James: that's fine with me just come back safe
Yumi: we will

The team walks away from the hotel and made there way to the store
Yumi: does everyone got there wallets so we can pay for this
The girls show there wallets
Minori: we always come prepared and never miss out on anyway
Yumi: good
Before they even had a chance to get there they were attack by a unknown yandere girl from nowhere
Murakumo: who are you and what's the big idea for attacking us for any reason

(Yuno Gasai from future dairy somehow got here from an unknown portal location)
Yuno Gasai: oh you know just a hunch but I had my certain eyes on a good looking human that I will be taking away from you
Shiki: and who will that be whoever you are
Yuno: that would be your husband James he is so cute and hot and I'll be taking him away
Yumi: you bet your ass you won't be getting your hands on him

Yuno: even the others who refuse to let me have their man I kill them while some manage to get away with there husband
Yozakura: I had enough of you
The girls transformed into there shinobi garb
Yumi: you made the wrong mistake and I hope you prepared for this

Yuno: I can hold my own even if I lose against 5 girls
Murakumo: let's do this

The gessen Girls Academy Vs Yuno Gasai
Fight

Yumi prepared the first strike and sends some ice shards to Yuno but she managed to dodge 4 of them while one hit her in the stomach
Yuno: ow that hurts
Yumi: that one hurt real good for you
Yuno: you got lucky but one won't take me down that easily

Murakumo with her duel swords sent a fury of strikes at Yuno but she saw through it and counter them with her sword but was unaware the wolves that are aiming at her
Murakumo: seek her my wolves
The wolves git to her and dealt some damage to her while a piece of her clothes were torn off
While Yuno was distracted by the wolves minori step up to the battle and beat her up with her bucket of candy (ouch that must have hurt her real bad) Yozakura came in to help her teammate with her hard hitting punches that took Yuno to the ground. Defeated but not out just yet

Yumi: ready to give up you can't win against us
Yuno: this won't even stop me from trying
Yumi: well in that case let's see if you can take my final form
A ice tornado surrounds Yumi as she transformed into Ice Queen Yumi
Yuno (Mind): I better retreat while I'm still alive
Ice Queen Yumi: I'm giving you a choice you either leave and not even try to steal our man or this sword will your death sentence, choose wisely
Yuno: this isn't over and I'll be back
She throws out a smoke bomb and disappears away from there sight
Yumi returns back to normal and goes back to there usual day to getting the groceries
Shiki: where did she even come from
Yumi: I rather not talk about it but let's get the stuff we were aiming for

They went inside the store and got the necessary stuff to make dinner and brought some lunch with them after paying the clerk the proper money and they went home to get everything started and James was worried about the dust that's all over his wives but strays from asking them questions

Somewhere far away from Japan
Another group of humans from another world are on a cliff overlooking the battle that just happen

Shido: interesting I've never seen them before
Kotori: could those girls be sprits they seem to have power that can be sealed but they are not from our world
Shido: I don't think so sister
Tohka:they are powerful from our perspective so there is no way they can be sprits
Yoshino: especially that ice women and her transformation it's quite fascinating to see in my eyes
Shido: what do you think of this kurumi
Kurumi: my time reversal probably wouldn't work in this world that we somehow got here from some portal that we were sucked into
But those girls do look interesting.
Origami: should we make our presence known to them
Reins: probably not we just got to this world and must know more about it before we can talk to them
Shido: good idea
Miku izayoi: don't forget about me I'm here as well shido
Shido: yes I know you are here but keep your voice down
Izayoi: sorry
Kotori: let's make haste to that city
The group immediately set there sights at Japan and walk to it since they are far away from it
(Chapter end)
A/N: what in the world is Yuno doing in this story and the characters of Date A Live as well. What do they have to do in this story but who knows what that answer will be
