With his literary lyrical world and genre-defying sound, Kitatatsuya is an artist with a unique presence.
In 2023, the company released "Ao no Sumika," the opening theme for the TV anime "Jyujutsu Kaisen" "Kaidama, Tamenori," which reached No. 1 on the iTunes overall top song ranking and 23 other digital chart titles, and surpassed 100 million total streaming views in just under three months after its release.
In addition to his activities as a singer, he has become a symbol of the current music scene, providing songs to numerous artists such as SUPER EIGHT and LiSA.

Kitani has written a new song, "Nakushimono," for the movie "Dekkichiage: A Man Called Murder Teacher," which will be the theme song!
As the lyrics "I don't even know what I lost, but I remember what I cherished" express, this song carefully depicts a feeling of trying to hold on to a glimmer of hope, even in the midst of a trapped situation, and is quietly nestled in the world of the work. The song quietly accompanies the world of the work.
About the song, Kitani said, "A person who has been robbed, destroyed, and worn out by others, knowing that he/she cannot get everything back, stands up again, believing in others and taking their hand. I felt that such strength is beautiful when I saw this work, and I put it into the lyrics and melody.He shared his thoughts with the audience.
Also, Ayano told us, "Mr. Kitani was very sincere in his approach to this work, and I felt that (this song) was the "last and greatest co-star. The lyrics are scattered in a good way, and I felt like they were desperately trying to pull together. I thought that this might be common to Yabushita, Ritsuko, and all the people living in that world. I was able to feel the music in a very deep way, and I really appreciated it.The comment, "I'm not sure how to do this," was received.
Shibasaki also agrees with Ayano that "It was reminiscent of the blurred parts of humanity. I thought the music was assimilated with the movie and was an appropriate song to conclude the film.He stated.
We hope you will enjoy this superb song that looks at loss and rebirth along with the film.
The latest trailer and scene photos released along with the theme song information are also noteworthy!

A reportage of an incident stranger and scarier than a story has been made into a film with a cast of splendid actors. This problematic film embodies the darkness that exists in modern society with unbearable tension and an unfathomable sense of despair! Please look forward to it!
