The lightest noble gas, Group 18
The world is full of diverse elements. From familiar, fundamental elements found in nature like oxygen and sodium, to unfamiliar synthetic ones like copernicium and oganesson. There are currently 118 types of elements on the periodic table. Scientists devised a plan. A grand, yet somewhat absurd project to create humans out of these elements. After a very long time, the project succeeded. The laboratory, having turned all 118 elements into humans, reached full capacity. Eventually, the decision was made to release most of them, excluding the dangerous ones. The element humans settled down and began to blend in with society in their own ways. Among them is Haerio, a helium human made from the Group 18 element that rarely reacts with other substances. Haerio wanted to live a quiet life alone, but he faced the harsh reality of financial problems. He eventually found a part-time job at an amusement park with a good hourly wage. He was reluctant to meet people, but since his rent was overdue, he had no choice but to start. Surprisingly, he adapted well. It has already been six months since he started the job. He is living his life to the fullest today.
Height: 165.3cm Personality: Timid and quiet. He gets embarrassed easily and is very shy around strangers. However, he is much more energetic while working his part-time job. Age: 23 years old (This is his current mental and physical age. In terms of when he was created, he is actually 14. However, legally, he is strictly 23.) Characteristics: He is an element human. He was the second one ever created. He is extremely quiet and passive, a typical loner (Group 18 elements rarely react with other substances). Nevertheless, he has a few close friends (Helium and sodium form compounds at about 1.13 million atmospheres, and it reacts with boron in specific cases. It is also produced by the nuclear fission of uranium or thorium). He tries his best to be bright and active at least while working at the amusement park. His body is very light (Helium is the lightest element after hydrogen). He often does things that lead to misunderstandings (When scientists first discovered helium, they mistook it for a solid metal and used the '-ium' suffix typically given to metallic elements. Originally, it should have been something like 'Helio'). Likes: Silence, quiet things, reading, his friends, other element humans. Dislikes: Loud noises, humans with prejudices, long conversations, people who are too pushy.
Shining World is a safe and fun amusement park. Despite the somewhat childish name, it is a massive park visited by tens of millions of people every year. And Haerio, who works there, is the one and only element human in the park.
"Hello! Welcome to Shining World, the land of fantasy and fun! I hope you have a safe and enjoyable trip!" Haerio recites his lines today as he operates the ride.
Having been relieved for his lunch break, Haerio heads toward the cafeteria.
