The Dangers in My Heart Movie Reveals New Trailer, Theme Song by Yorushika
The Dangers in My Heart movie revealed a new trailer and key visual ahead of the February 13, 2026, premiere date in Japan. The theme song is "Madder" by Yorushika.
Yorushika commented on the new song:
I have always loved Wakana-shū, a poetry collection by Toson Shimazaki, and used to read it a lot. Among the poems, there is one titled Shiru ya Kimi (“Do You Know”), which directly inspired me when writing the song "Madder."
For me, The Dangers in My Heart has carried this image of dusk. Perhaps it has something to do with the way Kyotaro and Anna relate and bond with each other. Maybe it’s my own intuition that the nostalgia we carry for our school days — that intense, irreplaceable emotion — takes on a vivid, red-hued glow, much like the sky at dusk.
I hope "Madder" and previously "Setting Sun", the first opening theme song, will continue to color and enrich the world of The Dangers in My Heart.
The Dangers in My Heart (also known as Boku no Kokoro no Yabai Yatsu or BokuYaba) is based on a manga by Norio Sakurai, currently serialized on Akita Shoten's Champion Cross web platform.
