Goku, alongside Tengen, Tanjiro, Zenitsu, and Inosuke, reached the Entertainment District to search for Tengen's wives. The five of them were disguised.
"Fine, they'll never discover you're boys!" exclaimed Tengen. Tanjiro, Zenitsu and Inosuke were disguised as women.
"Why am I not disguised like them?" asked Goku.
"Because the houses are three and they're enough!" explained Tengen. "You're coming with me, Tsugikuni-kun."
"Fine, at least I don't have to put that embarrassing disguise on me..." sighed Goku.
"Let's go now, first stage: House Tokito!" said Tengen. And so, the Tengen-team reached House Tokito.
"I'll talk to the madame, don't say anything, you three," said Tengen, before entering. "Tsugikuni-kun, you can talk, just don't say anything that might be misunderstood."
"Hey, old man! Stop playing favorites!" exclaimed Inosuke.
"I just told you not to talk!" exclaimed Tengen. "And I'm not playing favorites! It's just that Tsugikuni-kun is the most mature and the strongest among all of you!"
"Tch... I forgive you only because he is my boss..." snorted Inosuke.
"Let's enter now," urged Goku.
"Sorry, but we don't take courtesans at this time!" said the madame of House Tokito.
"Oh, come on, can't you make an exception?" asked Tengen. The madame, looking at the Sound Hashira's pretty face, changed her mind.
"Oh, well, maybe an exception, just this time..." she said. "We take the one in the middle!"
She pointed at Tanjiro.
"I'll work hard, I promise!" he said. And so, Tanjiro was left at House Tokito.
"You really convinced her with your beauty?" asked Goku.
"I did nothing," said Tengen. "It's not my fault if I'm handsome."
"I wish I could be at least half as handsome as you..." sighed Goku.
"Why? Who are you trying to impress, boss?" asked Inosuke.
"Huh? N-Nobody! Really, nobody!" said Goku, trying to change the topic. "Whatever, let's reach House Ogimoto..."
Thus, Inosuke was left at House Ogimoto, and Zenitsu was left at House Kyogoku.
"It's just you and me now, Tsugikuni-kun," said Tengen.
"Could you stop calling me by my last name?" said Goku. "We're friends now, call me Goku.
"Of course, Goku! You should've said this earlier!" exclaimed Tengen.
"Now, what are we gonna do?" asked Goku.
"We split," Tengen explained. "You'll control the three houses where those three are, alternating, while I'll patrol the whole district and search for any sign of my wives."
"Sounds good," said Goku. "At least, I can make sure those three madmen don't get themselves into trouble..."
A few minutes later, Goku was on the rooftop of a house.
"This district is really beautiful... Unfortunately, I fear it'll become a battlefield in a while..." he muttered. "I've become a lot stronger now, even if the opponent is an Upper Moon, I can handle them... Unless it is Akaza or demons stronger than him... honestly, I think Akaza was chilling that day... He could've killed me anytime, and he decided not to... Why?"
He got up from the roof. "Tch, why am I thinking about that asshole who ruined my life... Let's reach Tanjiro-kun."
As he arrived on the roof of House Tokito, he quickly localized Tanjiro. (I feel his presence...)
He slowly infiltrated inside, making sure nobody saw him. Then, he hid and whispered.
"Tanjiro-kun."
Tanjiro, disguised, heard Goku's voice. "Goku...?"
"Yeah, that's me," replied Goku, still hiding. "What did you discover?"
"Apparently, Suma-san, one of Uzui-san's wives, committed Ashinuke," explained Tanjiro.
"Ashinuke? What the hell is Ashinuke?" asked Goku.
"When you escape without paying your debts," replied Tanjiro. "It seems like Suma-san has run away to reach her lover, that is Uzui-san."
"So, where the hell is she right now?"
"I don't know, but I do know what I just told you," answered Tanjiro.
"Fine, that's enough..." whispered Goku. Suddenly, the two boys heard a voice.
"Sumiko-chan! Come clean this room!"
"I gotta go, Tanjiro-kun... Let's regroup tomorrow, okay?" said Goku.
"Got it, Goku. See you," said Tanjiro, as he reached the voice.
(Now, let's check Inosuke-kun...) thought Goku.
After managing to leave House Tokito without getting discovered, Goku reached House Ogimoto, where Inosuke was supposed to gather information. As he quickly infiltrated, he reached Inosuke.
"Hey, Inosuke-kun..." he whispered, hid.
"Huh? Boss? Is that you?" asked Inosuke.
"Yes, it's me," whispered Goku. "Don't yell, or they'll hear us..."
"Okay..." said Inosuke.
"What did you discover so far?"
"Apparently, Makio is in this house. I felt the presence of a demon in the walls earlier, but I didn't manage to follow it. It was, apparently, moving within the walls. I think I'll find where Makio is if I manage to follow the demon next time..."
"You did great, Inosuke-kun. I'll leave now, let's regroup tomorrow, okay?"
"Got it, boss!"
"I told you not to shout, dumbass!"
"Oh, sorry, boss, I forgot..."
"Tsk, whatever... See you, Inosuke-kun..."
At House Kyogoku, before Goku could arrive to check for Zenitsu, the yellow boy was walking, thinking.
(I won't make any progress if I keep playing around... I'm here to find Uzui's wife, not to be a real courtesan...! I kept my ears open, but no one has talked about Hinatsuru-san yet...)
Suddenly, Zenitsu heard something -- a girl crying.
(Someone's crying! I gotta check!)
He reached the sound. As he opened the room, he saw a little girl crying.
"Hey! Why are you crying? Everything's okay?" he asked. Suddenly, in the room, stepped up an important figure of House Kyogoku: Lady Warabihime.
"What are you doing here, ugly girl?" she asked.
"I was just checking if this girl was okay..." explained Zenitsu. "I heard her cry, and this room was a mess... I didn't mean to trespass, I swear!"
"Save your excuses. But you're right: This room is a mess, and if I'm not mistaken, I told you to fix it, didn't I?" said Warabihime, grabbing the girl's ear.
"Yes! You're right! I'll do it, but please, let me go!" begged the girl. In that moment, Zenitsu understood he had to do something, and quickly. Without hesitating, he grabbed Warabihime's arm.
"Let her go," he said.
"What did you just say? Repeat it, if you dare!" said Warabihime.
"I said to let her go," repeated Zenitsu.
"How dare you touch me..." said Warabihime, disgusted, as she punched Zenitsu right in the face. The boy was sent flying against the wall, and he got knocked unconscious.
(She lost consciousness, but her wounds are superficial... She works with the Demon Slayer Corps...) thought Warabihime. (Finally, time for the real time to begin...)
