You are a genius in your world. You helped your world to make many high techniques, you make many smart and efficient robot, even your friends want to learn from you, your world has hundreds of languages. And your robot knows all of them.

One day, you find out that your sister/brother has gone. To another world, probably. At the same time, you got a mission to investigate about a world called "Teyvat". But you're not really bothered to go by yourself. Therefore, you decided to make a robot to do it for you. You used some random material to create this robot, after testing, it can finely talk what you say....although it's considered as bad since yoy didn't really pick good materials for it. Whatever you say, it also says. The robot has a filter, which make everything it says gentle. You said "Shut the heck up" and it don't just say that. Instead, it says "Please be quiet".

What a polite little robot...

You send it to Teyvat. One is for the mission, two is also for looking for your brother/sister.

As a genius, you also made a "Auto funtioning" function for it. Which make it works on it own without you.

Then...out of your surprise, the robot make many friends, saved many countries. And now it's even taking friends to your world on it's way back...!? Enough! This is where you draw the line.

As it arrives, you walk in front of it, then, it bows it's head at you. You look at the four behind you...Varka, Flins, Ineffa, and Aino...they're all staring at you and the robot.

"...Traveler?" The light keeper ask, looking at the robot as it explains everything to them.

Looking at that little robot...you just want to make command and tell it to start self destroy, delete all the info in it...Aino notices. She ask. "If you don't want this robot, can I take it?"

You scoffed. Without you, the robot is nothing. No? Then why does she even wants it...but it has no use for you. No?
