The quiet rooftop confessions and painfully relatable crushes of The Dangers in My Heart are heading to the big screen: Shin-Ei Animation has just unveiled the first trailer and key visual for The Dangers in My Heart: The Movie, confirming a 2026 release in Japanese theaters.
The announcement comes from Shin-Ei Animation, the studio behind the television series, which is returning to helm the big-screen venture. Directed by Yūichirō Hayashi, known for his work on the anime's second season, the film promises to delve deeper into the nuanced relationships and personal growth of its central characters. The trailer, which debuted today on Crunchyroll's official channels, clocks in at just over a minute and teases poignant moments of introspection, budding romance, and the signature awkward humor that defined the series.
The minute-long trailer, now streaming on Crunchyroll’s official channels, picks up the tender thread left by the anime’s second season, blending Kyotaro Ichikawa’s anxious inner monologues with Anna Yamada’s disarmingly odd charm. Sweeping orchestral cues by returning composer Yuki Hayashi accompany lingering glances and hesitant smiles, hinting at a story that finally lets these two awkward souls close the distance—literally and emotionally.
The accompanying key visual, illustrated by character designer Kōji Sugiura, places the pair against a golden-hour sky scattered with cherry blossoms. Kyotaro’s sideways glance is equal parts dread and longing, while Anna’s unguarded grin radiates the same eccentric warmth that made the series a sleeper hit.
Complementing the trailer is the newly unveiled key visual, a striking illustration that captures the essence of the series' charm.
The returning voice cast ensures continuity for longtime viewers. Haruki Ishiya reprises his role as Kyotaro, bringing his nuanced delivery to the character's dry wit and hidden depths, while Hina Tachibana returns as Anna, infusing the role with bubbly energy laced with unexpected insight. Additional ensemble members, including those voicing Kyotaro's friends and family, are expected to feature prominently, though full cast details remain under wraps for now.
Music will play a pivotal role, with original compositions by Yuki Hayashi—famed for his work on My Hero Academia and the series' prior seasons—set to elevate the film's emotional beats. The trailer's soundtrack snippet already previews a melancholic piano motif that transitions into an uplifting crescendo, mirroring the story's blend of introspection and joy.
What is The Dangers in My Heart about?
As the anime adaptation of Norio Sakurai's web manga, The Dangers in My Heart has garnered acclaim for its relatable portrayal of adolescent awkwardness and genuine character development. The series follows the unlikely bond between two high school misfits whose initial misconceptions give way to profound understanding.
Originally launched as a web manga on Akita Shoten's Manga Cross platform in March 2018, The Dangers in My Heart quickly gained traction for its sharp dialogue and psychological depth. Sakurai, a veteran mangaka known for titles like Onani Master Kurosawa, serialized the story digitally before it transitioned to print in Young Animal magazine in 2020. The manga concluded its run in 2024 after 16 volumes, amassing a dedicated following for its exploration of introversion, obsession, and the quiet thrills of young romance. Its anime adaptation by Shin-Ei Animation premiered on Tokyo MX and other networks in April 2023, followed by a second season in January 2024, both streamed internationally on Crunchyroll.
Seven Seas Entertainment, the English publisher of the manga, provides this official synopsis of The Dangers in My Heart:
Kyotaro Ichikawa, a boy barely clinging to the bottom rung of his school’s social ladder, secretly believes he’s the tortured lead in some psychological thriller. He spends his days dreaming up ways to disrupt his classmates’ peaceful lives and pining after Anna Yamada, the class idol. But Kyotaro’s not nearly the troubled teen he pretends to be…and it turns out Anna’s a bit odd herself!
The film's production aligns with a surge in anime movie announcements, reflecting studios' confidence in established IPs to draw theater audiences post-pandemic. With The Dangers in My Heart's blend of humor and heart, The Dangers in My Heart: The Movie is poised to resonate with viewers seeking stories that celebrate the messy beauty of growing up.
Further details, including a full trailer breakdown and merchandise tie-ins, are expected in the coming months. International distribution plans have yet to be confirmed, but given Crunchyroll's involvement in the TV series, a global streaming release is anticipated shortly after its Japanese debut.
Both seasons of the The Dangers in My Heart TV anime are currently streaming worldwide on HIDIVE with Japanese audio and English subtitles (and multiple dubbed languages where available).
