Fate stay night world:
It had been a week since Illya joined the group and her world turned upside down. She felt her body was stronger and the support brought by Naruto's presence helped her mind.
Illya usually just watched the members talk as she didn't have any request and was shy about talking to them. In this week many things had happened, the war had started and her brother was now a master of the servant that her father had summoned.
During this week, Illya followed the instructions provided on chakra usage and trained to use the abilities provided as her mind knew them but her body didn't have the experience.
While experimenting she realized that her reserves of chakra seemed to be resonating with her mana reserves and increasing at an alarming rate.
So she opened her phone and asked Naruto after a few days of observation.
"Hmm, there is no problem just the chakra adjusting to your existence. I haven't explained what it is and how it worked so will let everyone know as I will gift to those who earn it.
You are special, Holy Grail.
Now, chakra is a combination of Physical energy and spiritual energy. It is combined naturally in my body and those I give the gift to but it can also be done manually.
Ki is physical energy and Monkey uses this energy, his world doesn't utilize spiritual energy.
Spiritual energy is used in Hybrid's world and they don't utilize physical energy.
Mana comes under spiritual energy part as it is connected to your soul. So if I give someone with chakra and they have one of the energies in high ratios than that energy will move towards balance so your chakra will increase at fast pace.
So if Monkey gained chakra then he will be directly increase in power by 3 or more times, only in energy as the rest depends on practice and skills. I hope everyone understood or you can just watch the video on the explanation, it goes deeper into the study so don't open it if you are Oppai Dragon." Lord Seventh (Naruto)
"Hey, I take offence to that. I can definitely go through it." Oppai Dragon (Issei)
"If you can go through it without losing focus, I will gift you a pair of glasses. Wink wink" Lord Seventh
"Deal" Oppai dragon replied with thumbs up emoji
"Thank you"
"No problem, I am always willing to help"
Illya smiled and made a sign for thanks in the snow outside the castle, and sent a picture to the group.
She felt embarrassed but the comments made her happy.
'It's nice like this but now I need to work.' Illya smiling face turned serious as she started moving and soon she was running at an inhumane speed
Illya had decided to learn her skills and for that experience was needed so she decided to move around herself.
Illya headed for her brother's place while Hercules moved beside her and they moved through the silent night.
"Hello, what beautiful it is." Illya muttered as she walked towards her target
Shiro Emiya with his servant Saber had just fought of the servant Rider alongside Rin Tohsaka and her servant, when Illya alarmed them of her presence.
"Who are you?" Shiro asked in cautious tone, he would have been nicer and such if she was alone as Illya looked like a little kid but the giant monster assured him that he needs to be wary.
Illya looked at him and then towards Saber, she didn't feel anything good for him because of her bias. She had talked to Naruto and knew that the information might be wrong, and she needed to verify it as the truth might be different.
'He is a nice person and broken. He is willing to die for his servant, how sad.' Illya thought
"I am a friend and here to stop the war. Will you work with me?" Illya said in a calm tone
"How can we trust your words?" Rin questioned as unlike Shiro, she was not trusting of others
"Shiro, where is your phone?" Illya asked as she knew he was a member of the group
"What does that have to do with this?" Shiro was confused now
"It will easily prove everything so where is it."
"It should be in my room" Shiro answered honestly, he didn't; use the phone much and forgot it at home
"Then let's go to your home, it's not like I don't know your address and my servant are already there." Illya replied with a smile as she started walking
Shiro stared at her with a conflicted expression, normally he would have called the police for trespassing but now he was in the magical world and there didn't seem to be any magical police force.
"You will learn to get used to it. Let's see what so special but have your servant ready for any change." Rin put her hand on his shoulder and whispered as she followed behind with Archer
Archer was an unusual servant and something about Illya was causing him to react and it was not because of familiarity.
'Gaia'

Dxd world
Rias sighed as she her new servant fall asleep trying to watch the video without losing focus.
'Lord Seventh really knows how to play with people's mind and heart.' Rias thought as she flipped through the conversations that had taken place as she was busy
'So many things happened in just less than two weeks. These people are really good at finishing tasks.' Rias mused as she saw Wang Lin's accomplishment and the rest of the talks, and the introduction of the video system
"Should I ask him?" Rias muttered as she sat in her seat inside the room of the occult club
"Ask who? Did someone catch the interest of our princess?" Akeno spoke in a teasing tone; she was the childhood friend and the queen of Rias
"I think I found someone that can help me but I am not sure if I should involve him in this issue." Rias replied as she thought it might become too big to handle
"Who could that be? Why not just talk to him or are they not trustworthy?" Akeno hugged her from behind and asked as he eyes were attracted to the phone
"I think he is someone to trust."
"Then just ask him."
Rias looked at the screen and typed as she was assured of her choice now. She just needed some guide as her life was about to be ruined.
"Lord Seventh, I need your help.
My hand has been given to someone for marriage since I was born but I do not wish to marry this person. I am unable to cancel it as he is one of the nobles and it will cause trouble for our family.
I wish to challenge him to a battle to cancel the deal but I am not sure we can beat him." Rias typed with frustration
Akeno was surprised at the method of communication and the name, "Who is this Lord Seventh?"
"Someone from another universe and from his words, an Immortal King." Rias replied
"If you wouldn't mind, I can give my advice as it seems he isn't available at the moment. What resources do you have at your disposal? What skills do you know? What does your enemy posses?" Don (Tsuna)
"Who is this?"
"Some crime lord from another world"
"You think he might help?"
"He doesn't seem normal and Lord Seventh didn't mind his intrusion. So let us try explaining it to him and Lord Seventh can see it later." Rias muttered as she explained her position and Don broke her group down into pieces while giving her advice on training programs and what skills they can use from Glutton.
Don gave them a class on flames and offered techniques for her queen plus some skills for her knight. He advised them to train Issei harshly if they wanted to avoid risks as he held great potential.
"Thank you for the advice and we will do our best to make this entertaining for the group." Rias typed as she looked towards Issei along with Akeno was giving a sadistic smile that caused him to shiver

Naruto World:
"Why didn't you say anything?" Kurama asked Naruto sat atop his head while they were in the forest of death
"I wish to see what they are capable of and she doesn't really need my help as I did give her the pawn. I will give them the option to learn some jutsu that I will convert into magic for them later." Naruto replied as he could feel the mana within his soul after he had copied Illya's inner being and his whole body was filled with magic circuits that were smaller than an atom and they made his body.
He didn't really need it but it would make new skills from the other world easier for him to learn and convert, and convert his for others.
"I wanna ask, is it supposed to hurt when you unlock your power." Hybrid (Ichigo)
"I felt really good when I unlocked my power." Monkey King (Goku)
"Mine was through a fruit and it tasted really bad." Straw Hat (Luffy)
"I felt good and hungry." Glutton (Toriko)
"Comfortable and invincible." Don
"It hurt so bad" Oppai Dragon answered after he had run away from the clubroom because of those ominous stares
"Nothing" Imagine Breaker (Touma)
"I was just born with it." Death of the Endless (Didi)
"So Lord Seventh helped unlock my power and it was really painful." Hybrid
"Hybrid, its Lord Seventh." Neo One for all typed like it was fact
"What does that mean?" Hybrid
"It means, he will cause you pain even if there is a painless alternative. His motto is no pain no gain so he is pretty much sadistic most of the time when in involves training. Lol, it had me laughing so badly that I might have just squished Lord Seventh. Lol" Lord Seventh
Grand Scholar (Wang Lin) added an alarmed emoji while Silent Beast (Gohan) used a horrified emoji as he was thinking of running away from home.
"Who are you?" Golden Fox (Yasaka)
"I am his immortal partner, the Kyuubi. You all can call me Kurama."
"Kurama, what are you doing? Do you want to feel what it feels to be run over?" Naruto asked as he floated in front of his face
"No" Kurama replied with sheepish smile as he knew Naruto wasn't kidding and the experience would be really humiliating
"I didn't make it painful but unlocking the power inside the mortal form that is not used to it is painful and lethal. I made sure you didn't die." Lord Seventh
"You forgot to mention about the pain." Hybrid
"Don't be a pussy and take it like a man." Lord Seventh
And a video of Ichigo and Issei crying in pain and crying was sent to the group.
"You should have just forgotten about it and trained like nice kid but you had to question me."
"What have you done?" Hybrid sent a meme of man with a surprised look
"Joking aside, I feel that things are moving too fast. I only had the phone for just two days and when I came to the phone after an hour it seems like a lot happened." Glutton
"All our worlds have different time except few of us might coincide." Lord Seventh
"Then how do we talk to each other so naturally." Don
Neo and the others also put a question emoji.
"The phone is a connection to me and through it I affect the world around you as my presence bleeds into your universe." Lord Seventh
"That sounds ominous" Imagine Breaker
"Agreed, I felt that was a line from a villain" Neo One for all
"I know but it's the truth." LS
"But what does that mean?" Hybrid
"It means I will end up controlling your universe if there is no competition. For now I just align the time for all of us when you hold the phone and operate it." LS
"Hory Shit, are you serious bro?" Glutton
