Hina Yomiya, the voice of Anna Yamada in The Dangers in My Heart anime, performed the opening and ending theme songs of the said series. Yorushika sang the original opening song and Kohana Lam did the ending song.
Studio Shin-Ei Animation is animating the series with Hiroaki Akagi acting as director. Jukki Hanada is writing the scripts, Masato Katsumata is in charge of the character designs, and Kensuke Ushio is composing the music. The cast of the main duo consists of Hina Yomiya as Anna Yamada and Shun Horie as Kyotaro Ichikawa. A creditless version of the opening song video was released last April.
HIDIVE and Bilibili are streaming the anime and the latter describes the plot as:
Kyoutaro Ichikawa may have the appearance of a typical middle schooler, but his heart is filled with murderous fantasies. It is therefore not surprising that Anna Yamada, the class idol, is constantly on his thoughts as the person he wants to kill the most. He unintentionally starts a meeting with Yamada while reading alone in his favorite school library, and she shows up to sneakily feast on her favorite candies and sweets. Ichikawa learns how much of a ditz Yamada is via their conversations and is forced to cheer her on from the sidelines. Yamada herself can’t help but tease Ichikawa nonstop because of his agitated responses. The distant connection between the two deepens into something more than just library acquaintances as a result of a variety of touching daily interactions. Ichikawa might eventually understand that his violent fantasies have changed into something quite else.
