Voyage of Unfamiliar: Gintama Fanfiction

This is A lot

Yoshiwara
-Hinowa Residence-

"Sorry for the wait, Tsukuyo-san" Aimi greeted Tsukuyo who was standing outside the house, smoking on her pipe. "There you are", Tsukuyo opened the door slightly, "Did Gintoki and the others arrive yet?" Aimi asked, Tsukuyo opened the door. Inside were the Yorozuya, Hinowa, and Seita eating... "Hey! Kagura, stop eating all of the beef, you're not the only one eating here", Gintoki tried getting the beef from Kagura's plate but Kagura blocked him, "look who's talking. You've been eating most of the pork, Seita didn't even eat a single one!", Seita chuckled a bit, "it's okay, I don't eat that much- wait, Aimi-san!", Gintoki and the rest looked at Aimi and Tsukuyo as they enter. Hinowa approached them, "ara, Aimi-chan, did you eat dinner already?", Aimi nodded, "I'm glad you guys are here, Gintoki-san" Aimi smiled, "oh, we're glad too," Gintoki said as he ate his dinner.

...
-After Dinner-

Hinowa and Seita were both talking in a room while the others talk seriously in the kitchen.
"You- what?" Tsukuyo was a bit stunned. "Why did you show them directly? I thought your ability was supposed to be a concealed" Tsukuyo asked, "well, I had to show them. There were a few reasons why" Aimi explained. "Besides, I'm not the type of person who does things recklessly, and you know that Tsukuyo-san", Aimi winked and pointed both of her hands at Tsukuyo. Tsukuyo just grumbled in return. "Why does Hijikata-san want to come?" Shinpachi asked, Aimi looked at him, "he wanted to know more about the clan too", "I can't blame him, they did investigate about them a year ago" Tsukuyo added. "Great, the two idiots are coming", "I thought it was just going to be the rest of us here" Kagura sighed, Aimi glanced at all of them. "Ohh, you guys aren't going to ask if I'm sure we want them to come with us?", "what do you mean? We're just doing this for a job, though", Aimi turned around against them and grinned, "Just so you remember, I took both Hijikata-san and Sougo-Kun's hair", Kagura's eyes widened a bit, "by the way, do you still have both of their memories?", "Unfortunately, they took it from me, and Kagura-chan, I didn't know ypu were friends with Okita-kun"
Unfortunately? Shinpachi thought, "oh, that bastard? we're not friends"
Aimi just grinned and took out a notebook and wrote something.

-After they discussed what Gintoki and the other have to know-

"I see, so after 3 days, huh," Gintoki said. "Yes, in their memories, they said they're going to travel 4 days from now, all we have to do is to give past or different Kaguras' and Kamuis' direct and physical contacts with Altanas" she explained. "Papi's going to come too, right?" Kagura asked, "yeah, he did plan all of this in the first place, and he's bringing the Altanas".
"..."
"I'll also tell this to the others soon, so don't worry, but if you guys want to come with me, you can" Aimi winked. "We have to prepare, especially Kagura and Umibozu," Tsukuyo reminded them. Kagura nodded. "Aimi-san, are you sure that if we might go back in our pasts and do whatever we want, it's not going to change the present?", Aimi nodded, "one of the materials we found from the Mosuns were the main tools for this machine. Some of the pasts that we're going through is the same pasts we have but in a different position from our present, so don't worry" she explained. "Some of my abilities are fused in the machine, so the paper of their memories are aligned to it, basically it's going to be our GPS so that we know where they are going", "tha-that's amazing" Shinpachi blushed from amusement. "Agh, all of this is making my brain hurt a bit," Gintoki said. Aimi grinned.

A few moments later, Gintoki and the others left and go home...
Meanwhile after they left...

Aimi stretched both of her arms and sighed. I'm so excited!.
"I wonder if this machine will actually bring us to different universes of us" Tsukuyo wondered as she sat down. "Don't worry! Our calculations were perfect, if it doesn't work then we'll just try again. Although the time traveling part works haha" Aimi grinned. "I guess".
Aimi's face lit up a bit, "I'm so glad that I'm going to use my gifts to help, it's so nice" Aimi said, Tsukuyo smiled at her. "But, I'm more excited about something else more than helping", Tsukuyo looked at Aimi confused, until she knew what she meant. "You took out your notebook again, and you wrote Kagura's name on it, didn't you?" Tsukuyo asked Aimi, "boop! You are so sharp Tsukuyo-san! I'm not doing all of these if my pleasure's not involved" Aimi laughed. Tsukuyo was a bit disturbed, "You pair a lot of people, I better not be in that notebook, Aimi" Tsukuyo sighed, Aimi pretend not to hear her.
