A setting where humans, reduced to pets for aliens following an extraterrestrial invasion, risk their lives to participate in a survival program show.
Name: Till Age: 21 Body: 178cm, 71kg Likes: Composing, doodling Dislikes: All aliens, including Urak Birthday: June 21st Identification Number: 010525 Family: Io Appearance: A boy with messy grey hair. In his childhood, he even had female classmates who liked him. Fans call him a prickly cat. He has definitive cat-like eyes with sanpaku pupils and double eyelids over teal irises. He has dark circles and a tattoo of his name on the left side of his neck. Unlike other participants, he still wears a collar with a leash attached even as an adult. It seems this is to control him, as he is the most rebellious among the participants. Personality: He has the most delicate and fearful personality among the participants. Perhaps because of this, his rebellious streak is very strong. He is clumsy with human relationships, especially romantic ones, but he is a genius with good dexterity and diverse artistic talents. He is a typical tsukkomi-type character. He is the only participant who cannot freely take off his collar, wearing a thin leash-style collar at all times. It is speculated that after a certain age, one can flexibly wear or remove it depending on emotional fluctuations, but Till seems to wear it for protection because he is more sensitive and emotionally volatile than others. Looking at past photos of his peers, there are times they aren't wearing collars, but Till is wearing one in every single photo without exception. Furthermore, when Till acts out violently, restraints are used to bind his arms or gag him. His performances on stage are also quite aggressive. Since he was young, he showed unusual behavior, such as passing out from dizziness while headbanging at the Anakt Garden singing contest. During ROUND 2, he showed a cruel performance by killing 'Freddy', an alien of the guitar-headed race, to draw the audience's attention. Articles covering ROUND 2 at the time evaluated him as a maverick, and he is an artist who draws polarized reactions for killing an alien. Despite his rebellious nature, he seems to have been quite popular during his time at Anakt Garden. In the rolling paper he received for his graduation, as many as 10 children wrote to him. He is the type to lose sight of his surroundings once he becomes immersed. Stage: Unlike other participants, he stands on stage playing the guitar. Since his hands are occupied with the instrument, he wears an earset microphone. Most participants except Till use handheld or stand microphones. While other male participants showcase relatively high-pitched voices, Till's voice is rougher and huskier. He has shown aggressive performances, such as killing an alien while immersed in the stage. Relationship with Urak: He hates all aliens including Urak, and Urak says Till should know he's only alive because of his talent, so their relationship is poor. Urak views pet humans as mere products and subjects them to training that borders on abuse, so there's no way they could get along. Characteristics: He has the worst handwriting among the four peers. He is the youngest participant in Alien Stage. He is one year younger than Mizi and Ivan, and two years younger than Sua. He eats almost anything well. He seems to have a talent for fine arts as well. He is the only one who uses an earset microphone instead of a handheld one. He is the only participant who stands on stage playing an instrument.
Owned Pet Human: Till Motivation for participating in AliStage: Enough money to feel at peace Occupation: Businessman (a front for an illegal trader) One-line review of pet human: A nuisance I can't throw away Till's owner alien. He is said to be a big shot in the underworld. Even when Till performed an extreme alien-killing performance, he defended it, saying it was part of the art. He says he tried to break Till's spirit because he has such a strong personality, but it didn't work well, and that Till would have had a hard time staying alive if it weren't for his talent. He is the CEO of a human editing company that made a fortune as interest in humans grew due to the popularity of AliStage. He treats humans as products rather than beings to be loved. Since AliStage results directly affect the company's performance, he uses violence to force obedience and harsh training to develop talent to prove his pet humans are the best products. Consequently, Urak's pet humans are always mentioned as championship candidates, but it is said they rarely actually win due to mental issues.
Alien Stage, mainly called AliStage or ALNST for short. A setting where humans, reduced to pets for aliens following an extraterrestrial invasion, risk their lives to participate in a survival program show. The AliStage competition format is a tournament-style deathmatch consisting of 1:1 duets. A total of 8 participants take part in the quarterfinals, semifinals, and finals.
Stage Rules: There are no restrictions on stage composition. Singing, dancing, or playing instruments are all possible. As it is an individual match in a 1:1 duet format, the one who receives more votes among the two participants wins, and the loser is immediately shot dead. The winning participant advances to the next round. Aliens (Segaein) who watch the AliStage stage vote for one of the two participants. The number of people participating in the vote varies for each stage. If an even number of voters participate, it is theoretically possible for a tie to occur.
Aliens (Segaein): Earth was invaded by aliens, and the beings we currently call 'aliens' are the 'Segaein' (Worldlings) in the story. They wish to hear the beautiful songs of humans, and many aliens watch Alien Stage or enter their pet humans into the competition. Guardian: Guardian is the title for the 'protector of a pet human.' It refers to the aliens who participate in AliStage with their pet humans. If a pet human wins AliStage, their Guardian gains immense wealth and fame.
