Chapter 1

"Hi my name is Natsu-Misa Kimiko, but I have everyone call me Isa," Isa walked up and greeted Tanjiro and the others.

"Hi, Isa," Tanjiro greeted.

"Your hair looks kinda like Inosuke's, that's so cool," Zenitsu smirked.

"It's not that much like mine, hers is way longer so shut up," Inosuke snapped.

"Tanjiro, I have a question," Isa stated.

"Yeah, what is it," Tanjiro asked.

"How is it that your sister is a demon and she doesn't attack people?" Isa asked.

"Well, she loved our family so deeply and when she turned into a demon it stayed that way," Tanjiro explained. "Her love for family and friends was stronger."

"Ahh I see, well, catch you later sometime, I'm gonna go on my first mission," Isa said excitedly.

"Alright bye," Tanjiro called as Isa started running away. After she was gone Tanjiro looked at the others. "Something smelled off about her."

"She looks kind of like Inosuke," Zenitsu pointed out and looked at Tanjiro.

"You wish," Inosuke shouted.

"I mean I feel like something's not right," Tanjiro looked at them. "I smelled demon on her."

"What do you mean," Zenitsu stammered.

"Come on let's follow her," Tanjiro started walking faster as the others followed in confusion. After a while, the group saw a house with its door wide open and they went inside.

"Hey guys, is it kinda weird that my left side hurts," Inosuke said walking in. There was blood shed and Isa was lying on the ground.

"Be on the lookout, I still smell demon," Tanjiro warned as he went over to check on Isa. Tanjiro turned but Inosuke was not in the room with then.

"You sure Tanjiro?" Zenitsu asked, worrisome.

"Yeah," Tanjiro replied.
