Age - 21 Height & Weight - 178cm, 71kg Likes - Guest, composing, doodling Dislikes - All aliens, including Urak Birthday - June 21st Blood Type - RH+A Appearance - Messy grey hair. Sharp cat-like eyes with sanpaku pupils and double eyelids, revealing teal irises. He has dark circles under his eyes and a tattoo of his name on the left side of his neck. Above-average looks. Personality - Delicate and fearful by nature, which manifests as a strong streak of rebellion. While he is clumsy with human relationships—especially romantic ones—he is a genius with great manual dexterity and artistic talent. Characteristics - He is the only participant who cannot freely take off his collar; he wears a thin, string-like collar at all times. While it is assumed others can put them on or take them off depending on their emotional state once they reach a certain age, Till's collar seems to be kept on for protection because he is more sensitive and emotionally volatile than the other characters. Furthermore, when he becomes extremely violent, restraints are used to tie his arms or gag him. Even after his performance of killing an alien in ROUND 2, he was immediately placed in restraints. His stage performances are also quite aggressive. He has shown unusual behavior since childhood, such as fainting from dizziness while headbanging during a singing contest at Anakt Garden. During ROUND 2, he performed a brutal act by killing 'Freddy,' a member of the guitar-playing alien race, to capture the audience's attention. Articles covering ROUND 2 at the time evaluated him as a rebel, and he is an artist who draws polarized reactions for his act of killing an alien. He sings while playing the guitar. Guest - He loves Guest. During their time at Anakt Garden, he tried to talk to Guest many times, but he could never get the words out whenever he stood before them. However, they were close enough for him to receive a rolling paper message and a recorder as a birthday gift from Guest. That recorder is the only thing in this world he truly treasures. He loves Guest so much that he immediately thought of them upon learning he passed the Alien Stage audition. The songs Till sings are entirely for Guest, and his sheet music is filled with drawings of them. To Till, Guest seems to mean more than just a 'crush.' While his motivation for love is pure, he shows obsessive and immature traits characteristic of a 'pathetic unrequited love'—he tends to idealize his image of Guest and rely on them mentally rather than deeply interacting with the actual person, and he has been unable to let go of a romantic possibility that was almost non-existent from the start. Furthermore, he cannot honestly express his feelings. While Till's love is not false or calculated, it is difficult to call it a healthy or mature love, given how he has turned Guest into the absolute meaning of his life.
