Sometime after Tsukiō and Batman agreed on working together, the latter decided to first register the former as a citizen of the Marvelous Kingdom of Anirabia. Thankfully, thanks to Batman's money and intelligence, it was a quick and easy process to make Tsukiō a citizen of the MKA. After that procedure is complete, the two decided to talk about Tsukiō's plans out in a fancy restaurant. They decide to go to the Demon Avenger Resturant, which is pretty well-known in the MKA.
Batman (who disguised himself as Bruce Wayne to keep his identity hidden): So, what do you like to eat? It's all on me.
Tsukiō: Wow, there are so many options to choose from. I can't decide on what to pick.
A waiter shows up and asks the two what to order. Bruce asks for a black coffee and orders a Hokage Alfredo for Tsukiō.
Batman/Bruce Wayne: it's an iconic dish in the restaurant. You'll love it.
Tsukiō: Seems like it. While we wait, how do I participate in the Ultimate Fantasy Tournament (UFT)?
Batman: There's actually a requirement to enter the UFT. To enter, one must gather 7 Major Insignias.
Tsukiō: Major Insignias?
Batman: They are entry badges neceary to enter the league. It is also a way to force any participate to get strong enough for it.
Tsukiō: OK (thoughts: They are kinda like gym badges). Are they neceary for systemers only or do all characters need to gain 7?
Batman: Systemers need to gain 7 of them, while fictional characters may only need less than 7 Major Insignias or none at all, but it varies.
Tsukiō: I see. Where do I g....
Waiter: "arrives and gives Batman his black coffee and gives Tsukiō his Hokage Alfredo" Here are your orders. Enjoy. "Leaves"
Batman and Tsukiō: thank you.
Tsukiō is certainly interested in the Hokage Alfredo dish. It's a dish of Penne Alfredo with white sauce on top, coated in Shinobu Powder, which makes anything stealthily delicious. He gives it a try while Bruce Wayne takes a sip of his usual black coffee.
Tsukiō: Bismillah. "Tastes it" Wow! It's so good! It seems like a paper bomb of sweet and sour has quietly entered my mouth! Thanks for the recommendation, Mr. Wayne
Batman: You're welcome. By the way, what were you about to ask?
Tsukiō: I was about to ask where to go to gain the first Insignia.
Batman: Of course. Each world has its own Insignia to get, and to that, I suggest the Demon Slayer world. There, you would gain the Slayer's Insignia. It's a common start for Systemers.
Tsukiō: Alright then. How do I gain the Slayer's Insignia?
Batman: To gain a Major Insignia, you must defeat an Insignia Master in its respective world in a fight. Since you are a Systemer, you can gain any and all abilities and powers from any power system in history, but you need to learn them first. It's not like Yuta's Copy ability or a Sharingan where one look in enough.
Tsukiō: Understood. Demon Slayer world it is! "He stops eating for a moment" Hey, Mr. Wayne.
Batman: yes?
Tsukiō: I know that there might be other Systemers like me but.. do you think that.... the MKA and all its connected worlds would accept a Muslim Systemer?
Batman: Don't worry, Tsukiō. This world is not just of white people only, but Asian, Black, Pakistani, and other nationalities and cultures, and we have a few Muslim heroes on our side too. So, if they can accept them all, they can accept a Muslim Systemer. Got it?
Tsukiō: Got it!
Batman: Good! Now, let me call someone to get some supplies for you.
Tsukiō: who are you calling for?
Batman: "smirks"
We cut to one of the ends of the MKA, where we Tsukiō and Batman (now dressed in his iconic batsuit) waiting for someone. Then, suddenly, a figure in a red and gold suit arrives from the sky.
Tony Stark aka Iron Man: What's good, Bats?
Batman: nice to see you again, Tony. This is Tsukiō, the Systemer I told you about on the phone call.
Tsukiō: The genius billionaire playboy philanthropist himself. It's such an honor to meet you, Mr. Stark.
Tony: No worries, my friend. Nice to meet you too. Here's all the crap that Bruce told me to get ya. "Gives him a backpack filled with certain items" it has all that Brucey told me to get ya. A sword. Some first aid kits. An e-map. Some extra clothing. Even some cash.
Batman: firstly, don't call me Brucey, stark. Secondly, take this, Tsukiō. " gives the latter something"
Tsukiō: what is it?
Batman: It's a Fictionphone. Essentially a smartphone linked to the MKA's tech and web system. Communicate it with me when you are about to go to another universe. You can also scan your Insignias to record them in the phone.
Tsukiō: woah. Thanks a lot, Mr. Wayne.
Tony: while you two say adios to one another, Imma just open up a Unigate real quick.
Tsukiō: Unigate?
Tony: essentially a public portal allowing one to go to any universe of choice. It also adapts your look depending on location, so that's a nice addition.
Tsukiō: woah! That's incredible.
Batman: now, Tsukiō, be careful of your surroundings and concentrate on your mission alone. Become as strong as possible but don't overstrain yourself. Got it?
Tsukiō: right! "Goes to the Unigate" wish me luck, Mr. Wayne.
Batman: Good luck.
Tsukiō goes through the gate.
Tony: I wonder what you see so special in that kid.
Batman: I know he is destined for greatness. That's all.
