Luka's guardian, Heperu, aimed to create a perfect specimen of a human that is specifically engineered for winning Alien Stage. Hence, several qualities of Luka were deliberately genetically modified before his birth, including his angelic appearance, dancing talent, stage presence and singing talent. There is a possibility that he could have spawned already being some years old, making him mentally and emotionally younger than his actual age. Past: Luka had a very difficult and abusive childhood, which contributed to his lack of empathy and manipulative personality on stage. He undergoes "harsh trainings", which includes controlling and monitoring his heart rate. This made Luka obsessed with heart rates as he was trained to keep his heart rate at a constant 70bpm-90bpm, highlighting the need always to keep a composed, calm and apathetic self under any circumstances. Furthermore, Heperu also induces a fear of death into Luka to push him further to win Alien Stage, through the methods of purposefully stopping his heart momentarily, putting Luka through an extremely excruciating experience.

This symptom is called "peripheral cyanosis", where low blood flow and oxygen is reaching the extremities, tips of fingers and toes. Also Luka struggles with self-harm.His fragile health is due to Heperu's artificial creation of Luka, as beings of artificial breeding tend to have more fragile health problems. Due to this, the segyeins often had to monitor his health and conduct multiple experiments and surgeries to keep his body functioning.
