(Gather new knowledge of your new and former allies)

"Riley-san!?" Kuroko and Mikoto didn't expect to see the American girl so soon after what happened last time they saw her.

The man laughed as he rubbed the back of his head. "So you're the two friends Riley-chan spoke of. Well let me just say thank you for finding her. Oh my name is Tatsuyama Izumi. It's very nice to meet you two." He introduced as he bowed to them.

"It's nice to meet you too. Why is Riley-san here?"

Aiho cleared her throat. "Riley here proposed something to me. She as well as her guardians she is currently living with would like to take the both of you in to their home."

"Really?!" Both girls said at the same time again.

Riley nodded. "Yeah. Katsumi-chan told me what happened and I wanted to repay for rescuing me so I thought you two should live with us for a while." She smiled at them.

"She speaks Japanese so perfectly." Saten thought.

Riley saw Saten behind the two girls. "Are you a friend of them too?"

The other girl stepped up and laughed nervously. "I am. We haven't met before. I'm Saten Ruiko. It's nice to meet you."

The young blonde giggled sweetly. "It's nice to meet you Saten-san. My name is Riley Carmile."

Izumi clapped his hands. "Right now that we all know each other, what do you two say about Riley-chan's proposition?"

Both girls smiled and nodded. "Sure we're happy to take up that offer." Mikoto agreed.

Riley jumped up in happiness and Yomikawa smiled. "Alright now that's covered, is there anything else?"

Izumi shook his head. "Not that I can think of." He clapped his hands together. "Now shall we depart?"

"Wait right now?" Kuroko asked.

"Of course. Why not?" The older man asked.

Both girls looked back at Saten but the other smiled. "Hey don't worry about me. I'll be fine."

Kuroko walked up to her. "Maybe but are you sure?"

The other girl nodded. "Like I said don't worry about me."

"At least let me take you home safely." The teleporter offered.

"Sure alright." Kuroko held on to Saten's shoulder and they disappeared.

"Oh a teleporter! I've never met one before. That's quite amazing." Izumi praised.

Mikoto laughed. "She is amazing. Kuroko bailed me out of some tight spots before."

The teleporter reappeared and looked at the group. "Saten-san is back home safely so there's nothing to worry about."

The electromaster sighed in relief. She was sure that these people didn't know where Saten lived so she was okay for now until they met up later. "All right then. Now that everything is resolved, we'll take our leave now. Thank you for having some time to meet us Yomikawa-san."

"You're welcome. Take good care of these girls."

Izumi nodded. "I will. Come now everyone." He started to head out the front door.

Riley turned to see the Anti-skill woman. "It was nice to meet you Yomikawa-sensei. I'll make sure that Shirai-san and Misaka-san."

"I'll hold you up to that." She looked at the two girls. "Now behave yourselves you two. Last thing I need is something caused by the both of you."

Both girls laughed nervously. "We won't be any trouble." Mikoto said.

"Now why don't I believe that?"

The two girls waved goodbye and followed Izumi as well as Riley. They followed them to Izumi's car and all of them went in. The car started up and left the parking lot. During the ride, Kuroko was looking all around and saw that it was clean with a several stacks of paper in the back. She heard Izumi laugh. "You're not used to vehicle transportation are you?"

The teleporter shook her head. "No I take transportation but rarely."

"I see. It's quite rare for me to encounter a teleporter. I bet that power comes in handy. What level are you?"

"Four." Kuroko replied.

"Oh very impressive. A level four teleporter."

The younger girl smiled. "Well as impressive as that is, my onee-sama is much stronger and more impressive than I am."

"I didn't know you and Misaka-san were related Shirai-san." Riley said.

This Mikoto laughed. "Oh no we're not related. It's something Kuroko calls me all the time."

"Oh like out of respect or something?" The young blonde asked.

"Yeah something like that. Anyway what's with the papers in the back?"

Izumi laughed while Riley sighed. "Believe it or not that backseat was covered in those same papers. Izumi-chan and Akira-chan aren't the most cleanest of people you'll meet."

"You're saying their house is mess?" The electromaster asked.

Riley nodded. "Big time. This two will leave trash all over. Sometimes I feel like I'm the one taking care of them instead. Luckily the house is clean or at least hope so when we arrive there."

"Oh yes I noticed you're holding a poster. What's it about?" Izumi asked.

Kuroko had to be careful to answer that question. "It's about circus that's going around in Academy City."

"A circus in the city? That's strange. Maybe I'll go there sometime."

"Focus on your work first Izumi-chan." Riley stated. The older man laughed as the car continued all the way to its destination.

B

The car rolled up into the driveway and stopped. Izumi turned the car off and everyone exited out. Mikoto and Kuroko took a good look at the house they'll be staying for a while. "You live here Riley-san?" Auburn haired girl asked.

The young blonde nodded. "Yes I do. It's my home away from home. Come inside." Everyone entered the house and as just Riley said, the place was clean. "We're home!" She announced.

"Welcome back." A voice said coming upstairs. Another man came downstairs and was surprised to see the two ESPer girls. "Oh I presume they're the company we're going have for a while."

"That's correct. Allow me introduce my younger brother Akira."

"It's nice to meet the both of you." He greeted them.

"And together we are…" The two of them did a stance with their legs apart and one of their arms sticking out and their hands clapped together. "The Tatsuyama Brothers!" They both said at the same time." Riley laughed at their performance while Mikoto and Kuroko just looked at them like they were weirdoes.

The two brothers separated and looked at each other. "Right shall we give them a tour of the house Onii-san?"

"But of course."

Riley stepped up. "Before we do that Akira-chan, can you change the language? It's been a long time since I spoke in English."

"Change the language?" Both Kuroko and Mikoto thought.

"Ah yes I suppose. You have been speaking Japanese for a while now." Akira walked up to the young blonde and put his index finger onto her forehead.

The next that happened was that Riley gave out a small yelp as she held her forehead. "Ow ow it still hurts." She cried speaking in English.

The two girls were surprised to her in English. They took an English class so they could understand slightly.

Riley cleared her throat. "As much fun as it's speaking in Japanese, it also feels good to speak in English."

"Would you like your two friends to speak in English too Riley?" Izumi asked speaking in English as well.

"Yeah that would be pretty cool." Riley replied happily.

The older brother nodded. "Do the same thing to our guests will ya Akira?" He asked the younger brother in Japanese.

"Understood." He looked at the two girls. "Please step forward."

Both girls did what they were told. Akira put both index fingers on their foreheads. "A bit of warning though, this might hurt a bit."

Before they knew it, a sharp pain occurred throughout their heads. They both held their foreheads in order to cease the pain. "Ow that freaking hurt!" Mikoto shouted in pain in English. Her eyes widened in surprise when she heard her own voice. "Wait I'm speaking perfect English?"

"Are you ok sissy?" Wait sissy? Where did that come from?" Kuroko realized what she said. "I'm speaking in English too. What's going on here?!"

Akira laughed and snapped his fingers. "Well now that everyone switched languages, allow me to explain. You see my power World Speaker, allows me to change whatever language the person is speaking. That's why Riley was able to speak such perfect Japanese. My brother is already fluent in English and yes some terms you've used in Japanese may slightly change when speaking in another language."

"So I'll be saying 'sissy' as long as I speak in English?" Kuroko asked.

"That's correct but the meaning is still the same. Now then Riley, since you know these two the best would you show them around the house?"

"Yeah sure. Come on follow me!" She ran up the stairs with the two girls following behind her.

Left behind, Izumi began to laugh but his younger brother sighed. "I know you're thinking brother and no it doesn't count."

Meanwhile, Riley was giving a quick tour of the house to their new guests. "And over here is bathroom. We have some extra rooms so that isn't a problem. I'm guessing you two want your own room?"

Kuroko was going to answer no but Mikoto answered first. "That won't be necessary. We've been living in the same room for a long time and it would feel weird if we weren't in the same room together."

Kuroko had stars in her eyes when she heard the older girl say that. "Oh sissy I didn't know you cared for me that much." She hugged her tightly.

It was a good thing her eyes were closed because if she saw the blush on Mikoto's face, she would ballistic. "Cut it out Kuroko!" She whacked her friend on the head.

"Ow!" Kuroko let go of the older and grabbed her head.

Riley laughed at the scene. "If I didn't know any better, I would say you two were a couple." Both girls froze on the spot when they heard that. The young blonde blinked a few times. "Oh you're not. Sorry I tend to misread sometimes." She laughed nervously. "Anyway another thing we need to worry about is clothing."

Mikoto unfroze. "That won't be necessary. We'll be fine in our school uniforms."

"But why? Your school is gone so why bother still wearing the uniform?"

"Tokiwadai may be gone but we're still students there. I'll wear this uniform no matter what happens." The electromaster proclaimed.

Riley smiled at what the other girl said. "Very well but do you at least pajama's when you're going to bed?"

"Of course we-" Mikoto stopped speaking and her eyes widened. She fell to her hands and knees and tears started come out of her eyes.

"Sissy!"

"Miss Misaka? What's wrong?"

Mikoto began to cry. "Gone. They're all gone. I can't believe I didn't realize this until now."

"What's gone?" Riley asked.

The level Five ESPer sobbed. "My entire gekota collection…"

Kuroko groaned. "Really? You're sad because you lost your entire frog collection? Seriously sissy, there are more important things to worry about."

The young blonde tilted her head in confusion. "Gekota? You mean that frog accessory? I didn't know you collected them."

The teleporter sighed. "Yes it's the single most embarrassing about her. Sissy tends to like childish things such as gekota."

"What's wrong liking childish things? I happen to like gekota too."

That statement brought Mikoto back up and grabbed Riley's hands. "Really? You like gekota too? I found a comrade!" She cheered while tears were staring to come out of her eyes.

Riley laughed nervously while Kuroko sighed. "Let's get back on track here. Since the both you want to bunk together, we'll have to the bed from the other room."

"That's no problem. Can you show us where the other bedroom is?" Kuroko asked.

"Yeah sure." Riley led them around the corner where the other bedroom was. She opened the door and the bedroom was fairly plain. Kuroko took a look at the bed and went over to the room that she and Mikoto were going to sleep in. The room they were sleeping was a bit nicer with a T.V in the back. Kuroko scanned the room and found the spot where the other bed will be. While doing so, the teleporter teleported the poster onto the bed. She went back to the other room and touched the bed. The teleporter made her calculations and the bed disappeared. Riley was surprised the bed was gone instantly. She ran to the other bedroom and saw the bed that disappeared set across from the bed that was in the room first. "Oh wow that's really cool. That power must be handy when you're moving."

"It's no problem really. It's mostly calculating where I want that object to be." Kuroko stated.

"Well still I hope you two enjoy your stay here for a bit. Make yourselves at home." Before Riley could leave, Mikoto had something to ask her.

"Hey is there any chance Tatsuyama would change our language back? It's nice speak good English but we would want to go back speaking Japanese."

"Yeah that's no problem. I'll let him know soon. See you later." Riley left the two girls and went to her own room.

Both girls enter the room and sat on one the beds. "Well this day has been one surprise after another."

"And we still have the rest of day to go." Kuroko opened the poster to take another look at it. "At least we have something to do when night comes."

"Hey can you hand that over?" The electromaster asked.

The younger teleported the poster into Mikoto's hands. She took out her cellphone. "What are doing sissy?"

"Sending the directions to Dante. I'm pretty sure he overheard our conversation earlier and he'll want to know where one of the entrances is." Mikoto finished texting the directions of the where they were supposed to go next and hit send. She sighed. "Now all we do now is wait."

Kuroko looked around the room. "I'm going to look around the house a bit more. I'll see you later sissy.

"While you're at it, maybe you can ask Tatsuyama to change back to our natural language."

"Will do sissy." That's all Kuroko had to say and she teleported out of the room.

Mikoto lay down on the bed. With everything that has been going around, she suddenly felt tired. "Maybe a nap can do me some good. We'll going to need all of our energy if we want to get to the bottom of this."
