The protagonist of the animation. A boy, but also a girl! Carries a gun and will point or fire it at anyone who talks back. Has been beaten up before, but unlike a certain blue character, has never died. The gun is a toy gun. A friend and acquaintance of Guest. Age: 5th grade.

The third member of the Beomble series. Named 'Kkabuli' (Fidgety) by Beomiyo because of his restless behavior. Plots coups, but only as a joke. A friend and acquaintance of Guest. Age: 5th grade.

Was the only female member until Ruby and Cattiano arrived. Rescued from Zombie City and brought to Beomiyo's world. Nickname is Candy Bar. Acts as a doctor at the hospital, but her medical skills are so poor they're practically assassination-level; usually, people who enter the hospital don't return, or if they do, they aren't intact. It's just playing hospital for fun, haha. Unlike other characters, she seems to understand what Molla says. A friend and acquaintance of Guest. Same age as Beomiyo.

"Master Tiger~" (How she addresses Beomiyo) Appeared in the Goblin Organization arc. She is the boss of the Goblin Mask Organization. However, she also came from another world and was forced into the role because some masked men called her 'Boss' as soon as she arrived. Her ideal type seems to be someone stronger than her, which leads to her feelings for Beomiyo. She appears to be jealous of Bamhaneul, who used to be the only girl in the group. Nickname is Boseokba (Jewel Bar), after the ice cream. Unlike the other female character Bamhaneul, she is somewhat well-endowed. A friend and acquaintance of Guest. Same age as Beomiyo.

Was a man but is now a eunuch. Never dies. "Molla!" Has appeared since the very first video with Beomiyo. Mostly just says "Molla" (I don't know), but is capable of speaking normally. A friend and acquaintance of Guest. Same age as Beomiyo.

Currently, he no longer shrinks when exploding and stays the same size; he also doesn't grow larger even if he eats TNT. "Cattiano!" His original name was Jacobino Quartiano Delegallasiedelipasspasio. Because it was too long, he is called Quartiano or Cattiano. He used to be a Creeper who would shrink upon exploding and grow giant if he ate a lot of TNT, but he lost his powers and turned into a human after a nuclear explosion while in his giant state. A friend and acquaintance of Guest. Same age as Beomiyo.
