Four months had passed since Goku's mission on the Mugen Train. Goku's arm had finally grew back, and he came back fighting and complete missions. One day, Goku was returning to the headquarters after a mission alongside Tanjiro. (If I think about the fact that already four months have passed since I fought Akaza, and since my Sun Breathing is known by Muzan, I genuinely don't believe it...) thought the boy. "Goku, you've been amazing earlier! You beheaded that demon with your Sun Breathing in a fantastic way!" exclaimed Tanjiro. "Eheh, thanks, Tanjiro-kun... You know, maybe, the fact that I can now use Sun Breathing in public is an advantage for me. I mean, I don't have to hold back to hide the Sun Breathing anymore" said Goku. "You're right, Goku! We're both Sun Breathing user, technically, but... Yours excels mine!" said Tanjiro."Of course it does, mine is real and pure Sun Breathing! You just inherited it from your father. And the name's not even the right one! Why the hell did you call it 'Hinokami Kagura'?" asked. "That's the name my father gave it" explained Tanjiro. "Oh, I see..." muttered Goku. Suddenly, Goku heard a voice. "Let me go!". It was Aoi. "What the hell is happening?" wondered Goku, walking towards the voice. As he arrived, he saw Tengen Uzui, the Sound Hashira, holding in both of his both arms Aoi and Nao. "Hey, Tengen! What are you doin!?" he yelled. Tengen turned. "Oh, Tsugikuni-kun! What a pleasure to see you!" he exclaimed. "Don't change the topic, let them go!" exclaimed Goku. "I can't! I need female soldiers for a mission!" explained Tengen. Suddenly, Tanjiro rushed forward. "Let them go, you monster!" he yelled, trying to headbutt Tengen. But the Sound Hashira disappeared and reappeared on the roof. "Did you really think you could headbutt him?" asked Goku. "Honestly, yes..." muttered Tanjiro. "Baka..." whispered Goku. "Anyway, if you need soldiers for a mission, Nao-chan is not a member of the Demon Slayer Corps, so let her go!" he then exclaimed. "Really?" repeated Tengen. "Then I don't need her..." he then said, throwing Nao away. "Whoa!" exclaimed Goku, catching Nao on the fly. "Then only Aoi-chan is coming with me!" said Tengen. "What if I come with you?" asked Goku. "But I need female soldiers..." explained Tengen. "I can disguise!" exclaimed Goku. "Answer me, Tengen: If I come with you, will you let Aoi-chan go?" he repeated. "Yes, I would!" exclaimed Tengen. "Since you're way more stronger than her or than anybody here, if you come with here, I'll let her go!" he repeated. "Fine! Then I'm coming with you!" exclaimed Goku. "And so let it be!" exclaimed Goku, throwing Aoi away. "Watch out, Aoi-chan!" exclaimed Goku, catching her on the fly. "When do we start?" he then asked, as he placed Aoi safe on the floor. "Now!" replied Tengen. "Fine! Let's go!" beamed Goku. "I'm coming too!" exclaimed Tanjiro, who was still there. "Ugh... Fine, you're as well!" said Goku. "Us too, boss!" said a voice. Goku turned, and found Inosuke and Zenitsu next to him. "Eh? You two as well? Aren't we a bit too many?" asked Goku. "The more, the merrier!" replied Tengen. "Even if the only one I like among you all is Tsugikuni-kun!" he then added. "I had no doubt about that, Tengen..." muttered Goku. "Let's go!" exclaimed Tengen then, jumping down the roof. Goku reached him, alongside Tanjiro, Zenitsu and Inosuke. "Where are we going, old man?" asked Inosuke. "In the flashiest place in all of Japan: The Entertainment District!" replied Tengen. "Sounds pretty cool. Let's not waste any time, let's go" said Goku. "Yes, but before we start, let's make one thing clear, guys:" said Tengen. "I am a God! Tsugikuni is my assistant! And you three are trash!" he exclaimed. "Straightforwward as usual, Tengen..." whisopered Goku. "Well, now let's go!" exclaimed Tengen, turning and starting to run. "Hey! Wait for me!" exclaimed Goku, running after the Sound Hashira. "They're way too fast for us..." whispered Zenitsu.
A few times later...
There was the moon, shining high in the sky, enlightening the streets of the Entertainment District. On a horse-drawn carriage, Goku was observing. He remained ecsatic: All those lights, people and population -- he was clearly not used to it. (These people... And the lights... Everything's beautiful...) thought the boy. Suddenly, Tanjiro, Zenitsu and Inosuke jumped off the carriage. "Those damn idiots! I just asked them to not to draw attention to themselves. A wall would listen to me more than them!" exclaimed Tengen, pissed off. "C'mon, let's search for them, Tengen..." said Goku. "Oh, Tsugikuni-kun, thank God you exist, Or at least, thank God you're not crazy like those three..." muttered the Sound Hashira. Once the group reunited, Tengen walked towards an uninhabitated room. "Come inside, Tsugikuni-kun and the others" he said. Goku and the others followed him. "So, Tengen, why are we here?" asked Goku. "I brought you here just to explain it to you, Tsugikuni-kun" answered Tengen. "We have to find my three wives. They've been here since a while, but they stopped sending me letters. So I've been searching for them, but nothing. However, I localized the three most likely places where they might me." In that moment, Goku's eyes widened. "Wait a second, Tengen, wait a second..." he whispered. "YOU HAVE THREE WIVES?!?" he then shouted. "Yes, I do!" replied Tengen. "ISN'T IT ILLEGAL?!?" asked Goku again. "Normally, it would. But I'm an ex shinobi, and my family practices poligamy, so I can!" replied Tengen. Then, Goku calmed down and sighed. "Fine. Now, where are these three places?" he then asked. "Makio is at the Ogimoto House, Suma is in the Tokito House, and Hinatsuru is in the Kogyoku Hourse. You'll get there in disguise and search for them" explained the Sound Hashira. "So... I have to act and dress act like a girl?" asked Goku. "Exactly" replied Tengen. "What a drag..." he sighed. "If you aren't finding your three wives, they're probably dead" said Inosuke. Tengen punched him on the gut. "You deserved it," said Goku. "I know...." replied Inosuke. "Anyway, shall we begin or not?" asked Tengen. "Yes, let's go. But tell me: Are your three wives hot?" asked Goku. "They are," replied Tengen. In that moment, Goku stood up. "Let's go." Then, he immediately walked outside the room. "wherever there are beautiful women, he dives in head first..." muttered Tanjiro.
