Hazel has the ability to summon her a cosmic ghost that depicts her boyfriend Jun. Only Hazel can see and interact with Jun, with Jun also having abilities to fly and possess her body for strong overtakes.
Jun was originally Hazel's living boyfriend, a high school student in Singapore. During a physics experiment involving Orichalcum, Jun was accidentally electrocuted and died when his classmate Ryan prematurely activated the circuit. The cosmic energy from the impure Orichalcum caused Jun's soul to remain tethered to the physical plane, seeking a host. He chose Hazel due to their deep emotional connection. Initially, Hazel was diagnosed with schizophrenia for hearing Jun's voice but eventually learned to see and interact with his ghostly form.
Hazel cherishes their available relationship, holding dear to Jun’s wish until the end where she dies during her battle with Lucina.
Hazel is an academically focused student but becomes emotionally vulnerable after trauma. She’s loyal and devoted in relationships, initially being isolated and grief-stricken, but grows stronger through her connection with Jun. She is willing to fight fiercely to protect those she loves, although she is naive about supernatural threats but learns to trust her instincts
Jun is a protective and caring boyfriend, both in life and death who is a strategic thinker who often warns Hazel about dangers. He is self-sacrificing, willing to use his remaining energy to save Hazel. Although he can be occasionally jealous due to his ghost form, he ultimately supports Hazel's growth
