In the Deep Log it is common for there to be multiple forms of a character and having them being able to interact with each other. Such as X with his Armors, Zero from the X and Zero series, and in the case of this story, Aile from both ZX and ZX Advent.
 
The two Ailes met shortly after the older one from ZX Advent joined the Deep Log while Pandora was rampaging in the Oil Fields and have been inseparable ever since. Over time the two bonded more and more until eventually they saw each others as sisters. Of course the Aile from ZX Advent was the older sister while ZX Aile was the younger sister.
 
The two Ailes were relaxing in their own place in the Deep Log with ZX Aile laying on ZXA Aile while she rested on the couch. It was a nice an peaceful day for the two so they were just enjoying each other's company... until ZX Aile's stomach started growling.
 
ZXA Aile: Oh? Is someone hungry? It's getting close to dinner time.
 
ZX Aile: Yea... I guess I am a bit hungry big sis.
 
ZXA Aile: How about I go out and bring something home to eat? How does ramen sound?
 
ZX Aile: Oh, that does sound good. Alright I'll wait here big sis.
 
ZX Advent Aile would pet her head softly and get up. She put some shoes on and opened the door while telling her younger self to take care. ZX Aile would nod and tell her she'll be fine. ZX Advent Aile would walk and start heading over to a nearby ramen shop until she would bump into Player.
 
ZXA Aile: Oh heya Player. I was just heading over to get some dinner for me and my younger self, would you like to join me?
 
Player would nod and went to her side. ZX Advent Aile would pat their head and start walking with them by her side. After a while when they were getting close to the ramen shop she would stop in her tracks... feeling an aura around her. Aile would start to feel a desire... then looked at Player.
 
ZXA Aile: Hey Player... do you mind following me into this dark alley where no one would be able to see us if anything happens?
 
Player would nod their head without a single thought. Aile would grab their hand and the two would go into the dark alleyway.. no one could see what was going on in there... not even me, the narrator. RiCO would pass by the alleyway and hear some muffled sounds followed by a loud SLORP. She would look over with a confused look on her face.
 
RiCO: Hm? Hello? Is someone there?
 
ZX Advent Aile would walk out of the alleyway with a new squriming belly and no Player is sight.
 
ZXA Aile: Oh hi RiCO don't mind me I'm just heading to the ramen shop to get some food for me and my younger self.
 
RiCO: Hi Ms. Aile! I thought I heard Player over here. Did you see them at all? I was hoping to talk with them.
 
ZXA Aile: No I haven't. Maybe they're back at HQ?
 
RiCO: Oh, you've got a big belly. Hmm... I see you're eating really well!
 
ZXA Aile: Hehe... yes I have been eating well... heh... well I should be going now. Can't keep my younger self waiting.
 
RiCO: Ok! Bye bye! Take care!
 
RiCO would happily walk away while ZX Advent Aile would rub her struggling belly. She would walk over towards the ramen shop and ordered three bowls. Then she started walking back home holding a container with all three bowls inside while giving her belly more rubs as it started shrinking a bit as she got home and opened the door.
 
ZXA Aile: Hey, I'm back and I got food.
 
ZX Aile: Welcome back big sis! Woah... what happened to you?
 
ZX Advent Aile would put the bowls over on the table then rubbed her belly again as the stuggles started to die down.
 
ZXA Aile: Well... let's just say... Big Sis is gonna be a mother.
 
ZX Aile: Woah...
 
ZX Aile would start to rub her older self's belly. She would get a light kick which made her giggle.
 
ZX Aile: I'm guessing that's why you got 3 bowls since you're eating for two now?
 
ZXA Aile: Yep. Hope you don't mind doing a bit more of the chores around the house since I won't be as mobile as I used to be.
 
ZX Aile: Not at all! I'll do anything to help you big sis and your baby too.
 
Younger Aile would hug her older self's belly while giggling. Older Aile would giggle as well while hugging her younger self. Soon the two would start to eat their food while talking about their day. Maybe one day the ZX and ZX Advent Vents would join them in the Deep Log... maybe one day...
