"So... we're good?" Asked Tanjiro awkwardly as the demon went back into the box.
"Yeah! We're good!" Said Aia.
"So what your telling me is that there's a demon hiding in PLAIN SIGHT with humans, and we have to find him/her?" Aia said, following Tanjiro.
"Well now that you say it, it's quite weird, but yeah." He said.
"Ok. But won't it hard to find them if they can blend in?" She asked.
"I have a good sense of smell, so I can find them." Tanjiro said.
"Oh! Like Ursaluna!" Aia exclaimed.
"Ursa-who now?" Tanjiro asked.
"Ursaluna!" Aia said, pulling out her Celestila flute and played an ominous melody. A brown quadrupedal bear appeared and after that, she played her flute again, and it disappeared.
"Ah, another Pokémon, huh?" Tanjiro said. Aia nodded.
They travelled for a day. The next night they arrived at a city. Tanjiro looked dizzy and the demon, called Nezuko, came out. The went to a udon stand and ordered one udon each. Suddenly, Tanjiro jolted up, startled. "Aia, take care of Nezuko, please." And then he ran off, pushing through the crowd. A couple minutes later, she heard a huge racket going on in the direction Tanjiro went. Startled, Aia told Nezuko to stay where she was and ran off to see Tanjiro pinning an unfriendly demon to the ground. The police were gathered around him. Aia could not let Tanjiro to get arrested. But then suddenly a nice smell flowed through the air, and the policemen fell asleep. "You still use the word 'person' for demons... so I shall help you." A woman emerged from the scent, and her arm was bleeding. Aia didn't really listen to what she said after that, as she was desperately trying to stay awake. The woman left with the unfriendly demon and an other unconscious woman, and so did the scent. Tanjiro stood up, and instantly Aia hugged him. "Tanjiro! What happened!? Who was that woman! I was scared!" Tanjiro looked extremely confused. They walked back to the udon station to see the shopkeeper shouting at Nezuko because of her bamboo muzzle giving her the incapability of eating. "Oh! I'm sorry sir, but the udon is for me, I'm sorry for the mix-up!" Aia apologized, taking the udon bowl and devouring it. When she and Tanjiro finished their udon, Aia turned to see a boy with green hair fading into black staring at them.
Aia: TANJIRO IT'S YOUR TURN!
Tanjiro: Geez ok, just please don't scream. Here's a Taisho-era secret: Aia apparently tried catching a demon more then once!
Aia: HEY! ARCANINE, USE FLAMETHROWER!
Tanjiro: OKAY OKAY I'M SORRY AHHHHHHHH!
