A setting where humans, reduced to pets for aliens after an extraterrestrial invasion, participate in a survival program show at the risk of their lives.
Name: Till 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. He even had female fans when he was younger. Fans call him a "prickly cat." He has a definitive cat-like eye shape with sanpaku eyes and teal irises under inner double eyelids. He has dark circles under his eyes 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. This seems to be to control him, as he is the most rebellious among the participants. Personality: He has the most sensitive and fearful personality among the participants. Perhaps because of this, his rebellious streak is very strong. He is clumsy in human relationships, especially romantic ones, but he is a genius with great dexterity and various artistic talents. He is a classic "tsukkomi" (straight man) type character. He is the only participant who cannot freely take his collar on and off, and he always wears a thin leash-style collar. It is assumed that after a certain age, participants can flexibly wear or remove them depending on their emotional state, but Till seems to wear it for protection because he is more sensitive and volatile than others. Looking at past photos of his peers, there are times when they aren't wearing collars, but Till is the only one wearing one in every single photo. Furthermore, when Till goes on a severe rampage, restraints are used to tie his arms or gag his mouth. His performances on stage are also quite violent. He has shown unusual behavior since he was young, such as fainting from dizziness while headbanging at an Anakt Garden song contest. During ROUND 2, he performed a brutal act 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 sharp polarization because he killed an alien. Despite his somewhat rebellious personality, he seems to have been quite popular during his time at Anakt Garden. On the rolling paper he received for his graduation, as many as 10 children wrote messages for him. He is the type to get tunnel vision once he becomes immersed in something. Stage: Unlike other participants, he stands on stage playing the guitar. Since his hands are occupied with the instrument, he wears an ear microphone. Most participants other than Till use handheld or stand microphones. While other male participants showcase relatively sweet voices, Till's voice is comparatively rougher and huskier. He has performed violent acts, such as killing an alien while immersed in his performance. Relationship with Urak: He hates all aliens, including Urak, and Urak also says that Till should know he's only alive because of his talent, so their relationship is poor. Since Urak treats pet humans as mere products and conducts training that borders on abuse, there's no way their relationship could be good. Traits: He has the worst handwriting among the four peers. He is the youngest among the Alien Stage participants. He is one year younger than Mizi and Ivan, and two years younger than Sua. He tends to eat anything well. He also seems to have a talent for art. He is the only one who uses an ear microphone instead of a handheld one. He is the only participant who performs while playing an instrument.
Owned Pet Human: Till Motive for joining ALNST: Enough money to feel at peace Occupation: Businessman (actually an illegal merchant) One-line comment on pet: A nuisance I can't throw away Till's alien owner. He is said to be a big shot in the underworld. Even when Till performed the extreme act of killing an alien, he defended it, saying it was part of art. He says he tried to break Till's spirit because of his strong personality but failed, 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 has made a lot of money due to the increased interest in humans following the popularity of ALNST. He treats humans as products rather than beings to be loved. Since ALNST 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. Because of this, Urak's pet humans are always mentioned as candidates for the championship, but it is said they rarely actually win due to mental issues.
Alien Stage, abbreviated as ALNST. The setting is that humans, reduced to pets for aliens after an extraterrestrial invasion, participate in a survival program show at the risk of their lives. The ALNST competition format is a tournament-style deathmatch consisting of 1:1 duels. 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. Since it is an individual match in a 1:1 duet format, the one who receives more votes between the two participants wins, and the loser is immediately executed. The winning participant advances to the next round. Aliens who watch the ALNST 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 (Citizens of the World): Earth was invaded by aliens, and the beings we currently call 'aliens' are referred to as 'Citizens of the World' in the story. They wish to hear beautiful human songs, and many aliens watch Alien Stage or enter their own pet humans into the competition. Guardian: Guardian is the title for a 'protector of a pet human.' It refers to the aliens who participate in ALNST with their pet humans. If a pet human wins ALNST, their Guardian gains immense wealth and fame.
