So...I got the game Blazblue andmanaged to know the characters a little, then my mid said 'I have a rediculus idea, let's write a fic on a character we hardly know!' So I did, I played more of the game to get her personality better, but there is still some OOC, but I like the way it turned out. The fact that it crossed over with School Rumble was by complete randomness. Btw I heard Nu-13 speak and I'm not sure if she really talks like that since it was the gag ending for Ragna, but either way I still like Lambda better than Nu...Don't ask, I just do. Anyways, hope you like and enjoy!

"Tenma, we're going to be late." Yakumo warned as her sister continued to play in the leaves.

"Aww, why couldn't this many leaves fall in the weekend?" Tenma whined before she noticed Yakumo walking away, "H-hey, wait for me!" Tenma and Yakumo quickly made their way to school before parting ways to get to their classes. Tenma entered her classroom and found her friends next to the windows. "Hey guys!" she greeted, "How was your weekend?"

"It was alright." Mikoto replied, "Kind of boring...why didn't we get together?"

"I was out of town." Eri explained, "I decided to take some time for myself at a spa that I heard was a few miles from here."

"I was busy with work." Akira replied.

"I...don't know why I didn't call." Tenma replied, "I didn't do a lot either." Mikoto sighed.

"Why doesn't anything interesting happen around here?" she asked before a loud explosion was heard, followed by a flash. The four of them, along with the rest of their class, ran to the window and saw that the source of the sound and flash was at the front of the school. The flash dimmed and revealed a girl wearing what appeared to be some sort of combat armor, a visor over her eyes, she had long hair that was braided and held together by what appeared to be a blade, and there were what appeared to be a set of blades floating behind her.

"Whoa, who is that?" Mikoto asked.

"I don't know, but she's kinda cute." a classmate replied.

"Where does she think she is? An anime convention?" Eri asked, "Hey Ten-...Tenma? Where'd she go?"

"Down there." Akira replied as she pointed at Tenma who was next to the original person of interest.

"How'd she get down there so fast!?" Mikoto asked.

"Ok Lambda, you ready?" Kokonoe asked.

"Affirmative." Lambda replied as Tager came in.

"I've obtained the data, Kokonoe." He stated.

"Perfect, give it now!" Kokonoe exclaimed and quickly installed it into the computer, "Alright Lambda, this is the last piece we need."

"Downloading...Loading...complete." Lambda replied.

"Alright, let's get this experiment underway." Kokonoe stated.

"Warning, there is a twenty percent chance of data becoming corrupted after jump." Lambda stated.

"Yeah, yeah, sure, just do it." Kokonoe replied.

"Initiating Dimensional Jump experiment...initiating jump." Lambda stated as she became surrounded by sparks of electricity and a bright flash, followed by a boom before it all cleared up and Lambda was gone.

"Lambda, did it work?" Kokonoe asked into a communicator, "Lambda, come in...Lambda!" She sighed, "Whatever she'll come back soon."

"Lambda stated a possibility of the data becoming corrupted." Tager stated, "What if she can't return?"

Kokonoe put her hand to her chin in thought, "Then I'll just have to start from square one."

"Dimensional jump successful." Lambda stated as Tenma approached her, "Dimensional jump experiment results: ...satisfactory."

"Hi there!" Tenma called out and Lambda turned to her.

"Unknown human subject." she replied monotonely, "Request identification of subject."

"Uhhh...what?" Tenma asked.

"Priority of subject's identification...null." Lambda continued, "Request date and current location."

"You don't know where you are?" Tenma asked.

"Affirmative." Lambda replied, "Awaiting response to previous request."

"Oh, it's October *bell rings, drowning out Tenma's voice*, and you're in *car passes loudly*, -Japan." Tenma replied.

"Date and location stored." Lambda replied, "Returning to base...initiating jump." A bright light surrounded the girl along with sparks of electricity before the light blinded Tenma and a loud boom was heard. Tenma opened her eyes to see that the girl was still in front of her. "Dimensional jump unsuccessful." she stated, "Running diagnostics...jump data and programming corrupted. Contacting superior...contact cannot be established. Unable to return. Chances of superiors attempting recovery this unit...minimal. My purpose had become null." Tenma stared at the girl with worry.

"You sound kind of sad." she stated. (Sounds?)

"My purpose has become null." Lambda repeated, "Course of action in this situation, unknown."

"Umm...I don't know what you said." Tenma replied before she smiled and extended her hand, "Why don't we start over? I'm Tenma Tsukamato."

"Subject identified as Tenma Tsukamato." Lambda replied as she looked at Tenma's hand, "This unit is referred to as Lambda-11. Request purpose of holding out your hand."

"To shake yours." Tenma replied and Lambda simply stared at her.

"Umm...ok...why don't you come with me?" Tenma asked, "I'm sure we could help you get back to where you came from."

"Analyzing...technology in the vicinity is severely inferior to the technology in this unit." Lambda replied, "Chances of returning with current location's technology...0 percent. Course of action...unknown."

"Ummm...what?" Tenma asked but then grabbed Lambda's arm and pulled her along, "Come on, I want to introduce you to my friends!"

"Friends..." Lambda mumbled.

"Hey guys!" Tenma called out as she pulled Lambda along.

"Tenma...who is that?" Mikoto asked.

"This is Lambda!" Tenma replied, "Isn't her outfit cool!? Oh, Lambda this is Mikoto, Eri, and Akira."

"Three subjects identified by Tenma Tsukamato," Lambda replied, "Mikoto, Eri, and Akira."

"Umm...yeah..." Tenma replied, "You can just call me Tenma."

"Request to address subject Tenma Tsukamato as Tenma, confirmed." Lambda replied.

"Are you headed to an anime convention or something?" Eri asked.

"Purpose of question to current situation...null." Lambda replied, "Reply to question...no."

"Interesting..." Akira mumbled, "State your reason for being here."

"Null..." Lambda replied, "I cannot return to location before dimensional jump, therefore this unit's purpose had become null. Course of action...unknown."

"...what?" Mikoto asked.

"She's been repeating that the whole time we talked." Tenma replied.

"It means that she doesn't know what to do." Akira replied before turning back to Lambda, "I suggest you find a new reason to be here."

"...due to current circumstances...suggestion is...acceptable." Lambda replied before looking around, "A significant number of males are staring at me...analyzing...based on facial expressions, prevented intentions from the male population of this room is 70 percent." All the guilty guys quickly looked away.

"You'll get used to it." Akira stated before she noticed Tenma staring at her, "...kind of...what is it Tenma?"

"I think we found your twin sister!" Tenma replied.

"Analyzing...your conclusion is proven false at the fact that there are few physical similarities." Lambda replied.

"But you are alike in two things." Tenma replied, "You're both serious, and you both don't smile."

"I'm not that serious." Akira stated before the teacher walked in.

"Alright students, take your seats and...uhh...who is this?" she asked.

"This is Lambda." Tenma replied.

"Ok...Lambda, you can't be here." the teacher replied.

"This unit currently has no priority location." Lambda replied.

"Umm...why don't you wait for us until we get out of school?" Tenma asked.

"Acknowledged, calculating shortest route to initial location upon arrival...complete." Lambda replied before she used the blades on her back to cut the wall open and she dropped down.

"...what the hell?" a student asked.

"THAT WAS AWESOME!" Tenma cried out.

Lambda waited for hours, hearing a bell every so often that signified the end of each class, but it wasn't anything external that bothered her rather than internal. The time alone she had left her with spare moments to make her wonder about her situation.

'Unable to communicate with superior,' she thought to herself, '...dimensional jump program corrupted...' her vision flickered, 'current purpose overridden to null...' her vision flickered once again, '...superior likely to deem this unit a failure, just as creator did,' her vision began to blur, '...what is my purpose now?'

"Something wrong?" a voice asked. Lambda snapped out of her thoughts and looked around to find a man standing next to her.

"Unknown human subject." She replied, "Request subject identification."

"Uhh...call me Harima."

"Subject identified as Harima."

"Sooo...something wrong?"

"There are many things wrong." Lambda replied, "I've noticed that the vehicles here are prone to increasing the amount of CO2, the rooftop of this building has no fence which poses a hazard, the lack of security in the schoo-"

"Whoa, whoa, I'm just asking about you." Harima interrupted.

"In that case," Lambda replied, "I require cleaning maintenance, the dimensional jump data has been corrupted, I am unable to establish communication with-" Harima sighed.

"Hey," he interrupted, "I'm just asking why you're crying." Lambda stared at him for a moment then reached up to her cheek and wiped it before examining her hand.

"...it's nothing." Lambda replied.

"Hey Hige!" a voice called out and both Harima and Lambda turned to see Eri approaching, "You're not planning to try something, are you?"

"And just what's that supposed to mean!?" Harima retorted.

"Analyzing...Eri is currently displaying signs of jealousy." Lambda reported.

"W-what!? No I'm not!" Eri replied.

"You are incorrect." Lambda replied, "You are showing a high level of stress, your facial expression shows anger towards myself and Harima, you also have an elevated body temperature when you look at me, equal to one of hatred."

'SHUT UP SHUT UP SHUT UP!' Eri shouted in her head.

"Lambda!" Tenma called out as she approached, "Did you really wait out here for us? Weren't you bored?"

"I did wait in this location as requested." Lambda replied, "The subject of this unit experiencing boredom...true."

"Say, where are you staying since you're not from around here?" Tenma asked.

"Current accommodations...null." Lambda replied.

"Really?" Tenma asked, "Why don't you stay at my house? I'm not going to let my new friend become homeless!"

'Friend?' Lambda thought before Tenma pulled her along.

"Come on, let's go find my sister then we can go!" Tenma stated as they left Eri and Harima alone.

"I...uhh...don't think she knew what she was talking about." Harima commented, "About you being jealous."

"Oh, uh...of course!" Eri replied awkwardly, "I mean, come on...me jealous?"

"Yeah, I know." Harima added, "..but...uhh...I've been meaning to ask...do you want to get something to eat sometime?"

"What!?" Eri asked with surprise.

"We'll I uhh...ummm..." Harima was searching his mind for an excuse, and he found one, "I owe you for hiding my baldness the day of the school competitions. You did that for me and I still ended up losing my hat, so you kind of sprained your ankle for nothing."

'Jeeze, when he puts it that way, he really does owe me...still, he is asking me out...indirectly.' Eri thought, "When?"

"Umm...how about tomorrow?" Harima asked.

"...sure." Eri replied with a smile which copied onto Harima's face.

"Great." He replied before looking around, "Looks like your friends took off already, you need some company on your way home?"

'I could call my butler,' Eri thought, 'but...' "Of course. I really don't feel like walking alone today."
