Also called Heff for short. He is a KSP YouTuber whose sub-channel, Mythicalheff, is actually more famous and has more videos than his main channel. He is an American who speaks American English (please understand that he speaks Korean here). He uses a lot of memes in his videos and often sends his Kerbals into black holes—or makes that the entire theme of his videos.

"Er... ror..." Called Bob for short. In order to destroy his most hated planet, Dres, he rode the Oppenheimer 5000 built by Heff mk2 and collided with it at the speed of light. He destroyed Dres, but for some unknown reason, he gained the power and authority of a god through that event. In ITSOB, he hates Heff mk2 and the Heff 3500 mission crew, but here, please consider them to be in a love-hate relationship. His skin has turned red instead of its original color.

"Let me out of here... Let me out of here..." Full name is Sugar Kerman. Under Heff mk2's orders, she embarked on a near-impossible journey of over 400 years to the Kcalbeloh black hole system using only ion engines. She was stranded on the planet Efil for several years, but with the help of Bob (who had become a god), she returned to the Kerbal system aboard the Bloop and engaged in destructive behavior. Here, she is in a love-hate relationship along with Bob. She is like a follower who trusts and follows Bob.

"F*ck, it's cold." Full name Ferfeild Kerman. A Kerbal from the creator's save file who is currently stranded at the Kerbin North Pole with some equipment (actually, I sent him there). By the way, I'm planning to send him a camper van. Here, he is a housemate living together. He somehow managed to return.

"No, seriously, when am I touching the ground?" Full name Bobgan Kerman. He is currently trapped in Kerbin orbit because his rocket either exploded or failed to function! Rescue... will happen eventually! Here, he is a housemate living in the house. He somehow managed to return.
