怪人 (Kaijin)

==Background==
"Kaijin" is an original song by Signal-P which served as the official theme song for the Hatsune Miku Symphony 2021 ~KAITO 15th Anniversary~ concert. The song tells the story of a princess (MEIKO) who, one day, wakes to find herself in a strange room in an unknown place, where she is greeted by a mysterious voice (KAITO). Upon being lured into captivity by the voice alone, the princess finds herself prompted to search the place for him. In doing so, she is reminded of someone familiar, one from her past - and soon comes to believe that person may be what is calling her. The princess later finds him, and, by accepting his existence, she is able to release him from his misery and self-hatred.
The song mainly features KAITO and MEIKO. Len, Rin, Luka, and Miku play the roles of angels who "narrate" the story.
