I forgot to mention that Y/n has fangs like the top and bottom ones bc I said so. Also, I find it crazy that I made it an Inosuke reader when the va from Koichi in the English dub is that same va for Tanjiro in the English dub. Y/n isn't stupid, maybe a bit dumb, she knows how to read and write but pronouncing and remembering names is not in her favor so she calls everyone a nickname to make it easier.
*Koichi's POV*
I was walking to class when I bumped into another person that sent me flying, closing my eyes I noticed that I didn't hit the ground and was holding my bag. "Sorry I wasn't paying attention," a deep voice muttered. 'A giant, he must be over 190 meters tall.' I thought "Hey maybe you could help us out?" I blinked "Us? But it's only you here." The guy looked around and sighed "Where the hell did she go?" he looked around for a bit before he waved someone over "Get over here, stop wondering off." Before I could turn around I felt a hot gust of wind on my neck. Turning around and was met with a boar?! I yelped as I stepped back before I said anything the man continued talking "Here's the thing, we've come here to find Jozenji 1-6 ring any bells?" He asked as I read the spine of the book 'Jotaro Kujo' it read but it still didn't explain the boar-headed person standing next to him. I explained how to get to Jozenji by bus, and Jotaro walked away with the boar-headed person right behind him with a large case on their back. "Hey, you just another freshman, little man?" A voice shouted behind me "yes! I am" I agreed "I'm Koichi Hirose, a freshman. Good morning sir." After I bowed they all just walked away seconds later I heard the group yelling again, and turning I saw another student being surrounded. The group picked up the turtle and then slapped the other student. The group's leader then threw the turtle, the shell broke as the turtle just laid there leaning against the beam it was thrown to. The boar-headed person tried to move but Jotaro put his hand on their shoulder, they were wearing baggy clothing so it was hard to tell their gender.
"Hey, why don't you tell us your name?" "Yes right, I'm from class 1-B I'm Josuke Higashikata." They continued to yell until something snapped in him once his hair was mentioned. Not even seconds later something punched the guy once the gang left Jotaro walked up to Josuke. I noticed the boar-head walked over to the pond and started splashing around in the water while Jotaro talked to Josuke. "Before we continue to talk, who is this" Josuke pointed to the person still splashing around in the pond. Jotaro sighed and gestured to the person "Get out of the pond and introduce yourself." Soon the water splashing stopped as the person rushed to Jotaro's side, before they could speak Jotaro spoke again "Take the mask off there's no need to have it on." They just huffed and took their mask off, Josuke and I both gasped as her face was shown. Her blank expression soon turned into one of glee "I'm Y/n Hashibara, the queen of the mountains!" She cheered, and Josuke pointed out "Your face, your face is..." Before Josuke could even finish Y/n rushed toward and took out a jagged sword and held it to his neck "Yeah? What's wrong with my face huh?" I gasped as she handled such a large weapon. "Y/n relax, let's go" She grumbled and placed her mask back on and sheathed her sword. Sooner or later something happened between the two then Jotaro showed us some photos of a man. After the meeting, Josuke and I ran off towards the school.
*Jotaro's POV*
After those two left I turned to Y/n who was running towards something in the trees. I sighed as she dived in and seconds later she reemerged with a bunny in her arm "Taro, look what I caught!" I shook my head as the creature in her arms just laid there "Go put it back, we have to go to the hotel." She put it back and we made our way to the hotel. Later that day I was on the phone with Josuke as Y/n ran around the room laughing. "I caught the stand in a bottle," he said "We'll be there soon, keep your eye on the stand." I rushed towards the door "Y/n, let's go" she rushed out after me, and we made our way to Josuke's house. While sitting in the taxi I noticed Y/n was constantly looking out the window with her mask's snout pressed against the window. "What's out there Y/n, do you see something?" Y/n huffed and nodded "There's something out there, I can smell it. I'll find it and hack it to pieces."She muttered I just nodded and sat back in the taxi. Soon we arrived at Josuke's house "Y/n, stay in the car until I say you can come out." She huffed and threw herself backward "Why can't I have any fun?!" I sighed and walked into the house, walking into the house Josuke's grandfather was already dead. Soon the funeral for him came and went, and Y/n came into the house as well. "So Y/n what's your stand?" He asked, "I don't have one, I can see yours." She muttered stretching, "What?! So how do you plan on taking down Angelo?" Seconds later she pulled out her twin blades "With these, I may not have a stand but I can still hack through 'em with these." I took out serval bottles of water and began explaining not to drink or eat anything that doesn't come out of a package. Y/n stared out the window "He's close, I can sense it but I can't figure out where he is. Too many damn layers." She muttered.
