Hikaru Kamiki/Relationships

Airi Himekawa (Victim #1)
At 11 years old, Hikaru was molested by the married actress and impregnated her, resulting in Taiki Himekawa's birth and getting involved in a murder-suicide with her husband Seijuurou Uehara after he found about it.

Because of Airi, this resulted in Hikaru targeting and killing actresses.

Ai Hoshino (Victim #2)
Ai is Hikaru's second victim (after the death of his first victim Airi Himekawa) whom he had a secret relationship with to the point that they slept together before they ended their relationship.

After breaking off their relationship, Hikaru unknowingly found out that Ai was carrying with twins (Aqua Hoshino and Ruby Hoshino) and he sent an obsessive fan named Ryosuke to murder her on the day of her dome concert.

Yura Katayose (Victim #3)
Yura is Hikaru's third victim who became drinking buddies before her demise when Hikaru presumably pushed her over a cliff.

Gorou Amamiya (Victim #4)
Hikaru gave information to an obsessive fan named Ryosuke about Ai Hoshino's pregnancy. With this information, Ryosuke found out that Gorou was the doctor to help Ai give birth, resulting in Ryosuke pushing Gorou off a cliff.

Taiki Himekawa
Taiki is Hikaru's son through the married actress Airi Himekawa.

Aqua Hoshino & Ruby Hoshino
Aqua and Ruby are Hikaru's twin children through Ai Hoshino.
