So, I really didn't think my idea would get this popular. As a result of this, I'm putting up a little author's note here to address some things. 1) Chapter length. I'm just kind of going to write each chapter hoping for about 1,000 words each, or until I feel like there's a good ending point. 2) Chapter schedule. I'm hoping to get a new chapter up every week on either Friday or Saturday. If I'm lucky, I'll be able to put out another chapter that weekend. If not, you'll just have to wait for the next Friday/Saturday. 3) Plot/Structure. I've got a vague-ish skeleton of the story I'm telling I might put more in to not rush the pace if I need to. Also, thanks for reading, favoriting and following. This is my first fanfic, so it's nice to see support.
Something that should've been in the first chapter: The following is a non-profit, fan-based parody/work . My Hero Academia is owned by Shonen Jump, Funimation, and Kohei Horikoshi. RWBY is owned by Rooster Teeth, and Monty Oum (Rest in Peace).
After Katsuki had almost been arrested by mall security for disturbing the peace, using his Quirk in public, and destroying mall property, he calmed down a bit. Well, as calm as Katsuki could be at any time.
"Look, if you don't want to talk about it, that's okay." Ruby said, shifting a little bit in her chair as she looked down at her food. Katsuki tightened his fists.
"Well, you were going to somehow find out anyway, so I'll give you the full story. Deku was a lot like you, actually. He was kind, cared for others around him, and he drew his strength from that. We were good friends a long time ago, and with how I treated him for so long after, I still can't believe he saved me." Katsuki explained.
"He sounds like a great person. I can't believe he would just disappear like that." Ruby said.
"Looks like you're in the same boat as Katsuki and I," Eijirou explained. "We think something's fishy about this. I mean, normally when people die, there's a body. But the heroes never found one. Not in Japan, nowhere. No traces of Izuku. However, when we asked around, other people claimed they saw some guy in this dark red coat talking to him." Ruby stood up, and pounded her fist on the table.
"That's him! That's the guy who was following me back home! Now he's here, too!" Ruby sighed.
"Wait a minute, Ruby," Tsu chimed in "We don't know how long it took you to get here, so he may have started in our world and ended up in yours. It also looks like he has the power to breach across worlds, so if we can find his home world, we can take the fight to him."
"We still need to figure out if he has a plan. We need to know why he brought me here, what he did with Izuku, and where he is." Ruby said, deep in thought. Then, Tenya, Ochako, and Mina walked up, ready to take Ruby to buy some new clothes.
"Round Face, Glasses, we got some news on Deku." Katsuki said, dead serious. Tenya and Ochako were shocked.
"Well, what do you have?" Tenya asked. "Right now, we need all the leads we can get."
"Um, it turns out that the guy who stabbed me and brought me here also was going after Izuku. This tells us random dude has the power to travel between worlds, and also bring people to other worlds. Izuku is most likely alive, just in a different world." Ruby explained.
After sharing their information, Ruby, Tenya, Ochako, and Mina set off on their own to pick out some new clothes for Ruby. However, Ruby put up a fight, saying she liked her hood and combat skirt, and that any change was a bad change.
"How about you use your hood and combat skirt as your hero costume? We have several people diligently working to ensure our costumes are upgraded and to provide us with support items." Tenya explained.
"Yeah! If you gave your scythe to them for the day, they could do some really cool things to it." Mina said, excited.
"No, I do all my own maintenance on Crescent Rose myself. In fact, I built it a long time ago, back when I was in your equivalent of middle school. Also, most students do maintenance on our own weapons. In Beacon, there was a huge weapons lab! And the teacher there was so nice! She let us come in and do whatever we wanted. She even had materials for us!" Ruby said, her speech slowly getting quieter and faster.
Tenya and Ochako looked at each other, with a tint of melancholy in their eyes.
"She is just like Izuku. Honestly, the resemblance is uncanny." Tenya said.
"I know. Somehow, something is different, too. I feel more relaxed around Ruby than I do Deku. When Deku was here, my heart would skip a beat every so often. Now, things are different. Anyway, do you think we'll get him back?" Ochako said, putting a hand on Tenya's shoulder.
"We will. I have a feeling Ruby ties in to all of this somehow. I am not sure, but I do know that we must focus on the here and now. If Izuku were here, he would tell us to be the best heroes we can be." By now, Ochako and Tenya had lagged a couple feet behind Mina and Ruby, who were talking excitedly.
"Hey, Tenya and Ochako!" Ruby called out. "Are you coming with us?" Tenya and Ochako caught up, and the four went to check out new clothes for Ruby.
The first outfit Ruby picked out was a pair of jeans, a dark red t-shirt, and a black hoodie, causing Mina to demand a fashion show must be held with that night. The second outfit was a long-sleeved gray shirt and a dark red skirt. The third outfit was a gray t-shirt, another pair of jeans, and a red leather jacket.
After trying on a few more outfits, Tenya said he needed a break from shopping, and the four walked and talked around the mall, with Mina being the most inquisitive about Ruby's home.
"So, what's each member of your team like?" Mina has asked. "You talk a lot about them, but you really haven't told us anything about their personality or abilities."
"Well then, we'll start with Weiss, or as others call her Weiss Cream." Mina and Ochako chuckled at the Schnee's nickname. "She is the next in line to be the president of the Schnee Dust Company, and so her rich upbringing made her a little bratty at first. We had a bit of a fight at first, and she didn't trust me at first, but now we're best friends! Blake is, well, Blake. She is reading most of the time, but she's good in a fight, and is a really nice person when you get to know her. She can make a clone of herself to take a hit while she repositions. Yang is really outgoing, and is passionate about what she does. She can deal double the damage after she takes a hit." Ruby explained.
By the time Tenya, Ochako, and Mina finished asking their questions, it was time for Ruby to have dinner with Momo and Shoto. The two were clearly overdressed, with Shoto wearing a blue dress shirt and khaki pants, and Momo wearing a white blouse and black dress pants.
"I'm sorry, but we really haven't been out to eat at a mall, and didn't know how to dress." Momo explained. Ruby just shrugged it off, saying it wasn't that big of a deal.
"Ruby, your world sounds really interesting. When this whole mess is over, and you get back home, do you think we could visit your world sometime?" Shoto asked. The further he could get from Endeavor, the better. Ruby said something, but it was obscured by the cookies in her mouth. After swallowing, she gave an actual reply.
"Of course! I bet some of my friends would love to meet some of you." Ruby said. The rest of the day went fairly smoothly for Ruby, going back to the dorm, having a fashion show and showing off her new clothes to the other girls, and setting up her dorm room. Little did anyone know, trouble was brewing.
