"Oh...sure," Takahisa said, unaware of what Armin heard from that strange cat. He got up in case this were a private conversation.

---

"I'm not the type of person to just stand there and watch," Kaika whispered back before finally settling in her seat. By now, the bell rung, and it was the start of this class. Of course, there were those confusing math equations, and yet, despite Kaika's constant ignorance of basic things, she just seemed to like math more than any other academic course for some reason.

Armin set a hand on Takahisa's back. "Walk and talk..." he said, beginning to walk out of the mess hall.

---

Eren drew and took small notes during the class, occasionaly glancing over at Kaika to see what she was up to.

"So...er, what's this about?" Takahisa asked as they walked out of the mess hall, not sure where this was going within their upcoming conversation.

---

Kaika was silently doing the math notes, but since she wrote so small, it was practically a mesh of numbers and words all over her notebook paper.

Armin took a breath. "Okay, I don't know if I might sound like a lunatic, but that cat talked...more specifically talked to me...." He glanced over at Takahisa. "What'll happen to Eren when he returns?"

---

Eren looked over at her and smiled, stiffling a chuckle at Kaika's mess of numbers and words.

"Oh yeah, that cat..." Takahisa mumbled a bit, not so bothered by that as he's seen weirder himself, however, he froze when Armin asked about this next question. For once, Takahisa was actually hesitant to say it. "...I'm not even sure if there's another way...but we have to..." Takahisa spoke, but wasn't able to say the last few words as it was something that he thought it would shock Armin.

---

Kaika only rolled her eyes, but at least it gets the job done. At least this isn't calculus, that would probably confuse the shit out of him... she thought, since she always found Geometry easier than algebra. It did make her wonder on how he was putting up with this kind of math.

Armin didn't look at Takahisa. "You'll have to kill him, won't you?"

---

Eren took some more.notes, then went back to drawing.

"If that's the only option...yes," Takahisa said grimly, but happened to reference if there was a possible way besides that, which he didn't know at the moment.

---

After finishing the notes for this class, Kaika went and fell asleep on the desk one more time. This is probably why she chose to sit all the way in the back.

Eren looked over at her and sighed, kicking her in the leg. "Hey.... Wake up..." he murmured.

---

Armin sighed. "Eren has a hard time dying.. He's been eaten twice, crushed by things a bajillion times, and pierced through vital places saints know how many times...."

This time Kaika had a hard time actually waking up, murmuring things like "Sota-kun" or "muffins." It was actually surprising that the teacher hasn't noticed that someone was asleep in the class.

---

"He's gone through that much?" Takahisa said with a surprised look, only knowing that his friend Kaika had gone through just about a ton of crap that should had killed her, but she still lives to this day.

Armin nodded. "Yeah, he's even been beaten to death by Rivaille Heichou..."

---

Eren swung his leg across the aisle of seats and nailed his foot right into the center of Kaika's shin. "Wake up.." he hissed.

Kaika was finally woken up from that, shaking her head a bit to resituate herself. She looked at Eren with a goofy grin, somewhat still a little sleepy but at least she was awake this time around.

---

"Yeah..." Takahisa said, but then started to catch onto something,"You said that a..er, cat told you that? About....you know..."

Eren sighed, shaking his head. "First, you attempt to kill someone, and now you're trying to sleep? I swear, you people are just plain weird..."

---

Armin nodded. "Yes... It sounded like a woman though...."

"Well...it's normal for me, been a year since things got different..." Kaika whispered back, since at this point, it was hard to see what was normal or not.

---

Takahisa froze once he pieced that this cat talked to Armin and that it sounded like a woman. "I think...I know who that could be..." Takahisa said with a shaky tone.

Eren sighed. "I.... I'm sorry.... It's just... I guess I'm jist a little shaken up right now...."

---

Armin looked at Takahisa. "W-who?"

"That was Bernkastel...a powerful Witch that can actually kill me or my other friends back at my world," Takahisa said, remembering that cold stare from that witch some time ago. Sure, Kaika had some power to keep Bernkastel at bay, but she wasn't here, which collected fear for Takahisa as he was unsure on what to do against a Witch in the first place.

---

"Well...can't blame you, I got you into this first of all," Kaika said quietly.

Armin put an arm around Takahisa gently. "She kept telling me not to trust you.. But I nelieve that if you truly trust me, I should return that trust..." he said, watching him.

---

Erennodded. "Well, I just have a question..." he said quietly. "What do I do if my titan side was triggered her ib your world..?"

"If that happens...I'm actually not that sure.." Kaika says, but sounds a bit stuck as she could somewhat remember there's some kind of war going on in different countries,"Let's just say it wouldn't be easy to get you out of trouble. Literally, private military companies here are pretty brutal, especially with those cyborg soldiers and metal gears....I'll tell you more about that later..." Luckily for them, there wasn't exactly anyone sitting near them during this class, so their conversation was basically unnoticed by anyone.

(Dunno what I'm starting on here, but to get something going on this timeline, I'm adding in some plot from Metal Gear Rising. So there's that. xD Would be amusing to see Titan Eren go against a huge Metal Gear. )

---

"We both trust each other, which is something that she can't change," Takahisa said, but still had a feeling that Bernkastel wasn't finished messing with tings here...

(Nice job, yea that wuld b interesting..)

Eren nodded. "Ah, I guess I'm so used to beibg the military that I wouldn't know what the military here is.." Eren looked at her. "Well, just make sure I don't get overly pissed or stabbed, or cut, cuz if so, BOOM, I go from five foot six to twenty foot nine in two seconds." he said to her.

---

Armin rubbed Takahisa's shoulder reassuringly. "I wont let her hurt you... I promise.."

Just as the timing was perfect, the bell rung to end this class, right on time to give Kaika some time to explain several things to Eren about the whole military detail. "Actually, a few weeks earlier, when I had some targets, I ran into one of those private military companies, not that I was directly involved in it. Apparently, there isn't a primary and stable military, so it kinda broke off into these small groups of different militaries, and with the advance of technology in the past years, most of those military companies have cyborgs and unmanned robots in their weaponry arsenal. Just a rundown on cyborgs, those are pretty much human soldiers but with robot parts replacing their normal human parts. Like, me with a robotic left arm that can shoot like a gun," Kaika explained to him in a whisper as she got up from her seat and began to walk out of the classroom. However, as they were in the hallway, she heard that her cell phone was getting a call from Nero.

"Huh?" Kaika blinked and answered the call,"What the hell Nero? I'm at school, are you trying to get me in trouble?"

/"I'm not, this is serious Kaika. Remember what happened a few weeks ago...apparently even I couldn't hack into their database and figure out what they're planning since they got a glimpse of you as the Violet Assassin, they're going to attack the school in a few,"/ Nero said seriously, warning her of something that didn't sound like any good.

"Are you fu-...fine, I'll stay on my toes and ..." Kaika replied back on the phone, but saw something that resembled a missile aim for the building, and quickly dragged her and Eren out of the blast vicinity once the missile exploded into the building and the hallway they were in.

"Shit...I'll call you later Nero, I think it's starting..." Kaika cursed and hung up the call, and towards Eren,"Things just took a turn for the worst, maybe my assassin persona is being targeted by one of the military companies, and probably narrowed down the school just to hunt me down. All of this to search for some assassin, just great...but most wouldn't go this far." Looking outside, Kaika spotted the thing responsible for the sudden missile fire, and it was a huge robot. While some people wouldn't know this, that encounter that Kaika had with one of the military companies, Desperado, reminded her that this was one of their creations, Metal Gear RAY.
(And, there we go. xD I'm thinking that Metal Gear RAY is about 40 to 45 feet tall, so it's pretty big.)

---

"I won't let her hurt you either, I won't," Takahisa says, getting a slight memory flash on how Kaika was almost killed by Bernkastel.

Armin smiled. "Why don't you go down to tge training yard? Heichou's doing a training segment, and I need to stop by the library before I begin mine."

---

Eren's eyes widened when he saw it. "Shit... That thing is, like, colossal titan huge...."
