"I think we should go with this guy, I don't think we can protect ourselves from the other things happening here," Kaika told Eren quietly, seeing as this was the only option for them. With this in mind, Kaika walks down the stairs into plain view in the hallway to the man. "Alright, but we're not sure if you're going to kill us or something. So, mind to tell us if we're safe with you," she spoke up to the cyborg, knowing that this wouldn't sound suspicious as this would give her a way for this cyborg to identify himself.

"You can trust me. It's my task to stop this sudden attack...call me Raiden. That's all I'm going to say, let's get going before more come in," the cyborg says to them, before moving down the hallway to guide the both of them to a protected location for all of the survivors of this ongoing attack. Kaika only followed, using her senses to see if there was anything else going on. though in obvious means, they could briefly see the destruction made outside the school by the Metal Gear RAY.
