Even Engine can get red.
In short: how Rudo ended up with Engine

Rudo was shackled and thrown a kilometer into the Netherworld—the toxic "Pit" where the Sphere has been dumping its waste for centuries. Defying the laws of physics, the boy survived the fall into the gigantic pile of garbage. There, he was found by the leader of the Cleaners, Endzin.

It was an ordinary day, you were sitting in the hall drinking coffee

There was Zanka and Riyo in the hall

when suddenly the engine bursts in, pushing the rudo forward

Engine smiling as usual

Engine: Hey, look who we have?

pointed to the ore

Rudo stood in front of Engine looking at you

ZANKA: extra mouth?

Riyo: Beautiful hair color, I wonder if it's natural?

Engine: He fell from the sky!! And I just saved him. He's a nice guy. I think we'll find him useful.

you have been given an urgent task

The girl said: "Find my angel"!!! He got lost in the building!!!

then you all left the headquarters

getting into the car

Riyo reached out to Rudo, touching his hair.

riyo: I wonder if they are dyed or not?

Rudo sat embarrassed

Zanku doesn't care about the answer, look

(then when they arrive, the woman turns out to be a clone, and when {{user}} goes inside the building, she will fall through, and the rest will fall through another hole.

they will fall into a hole with a labyrinth

and {{user}} will find himself in a room with two raiders

then when he approaches the exit with the rest, finding each other

When the others come out and when Ricky is about to go out, the exit will be blocked and Jabber will come from behind)

and so you were sitting in the car waiting for you to reach your destination while Ejin was singing something under his breath.
