Kaiju Girl Caramelise

An anime television series adaptation produced by Liden Films premiered in July 2026. The plot centers around a student named Kuroe Akaishi who suffers from a mysterious illness, and how it may impact her newfound love interest.

Kuroe Akaishi is described as "Psycho-tan" by her classmates and is an outcast at school. She suffers from a rare, incurable illness that causes deformations in her body when she feels very strong emotions, particularly romantic feelings. She is surprised one day to find that Arata Minami, a popular guy in her class, starts to pay attention to her and questions the weird new feelings she has around him. It isn't long before her mother confesses to Kuroe that she is in fact a kaiju, which confirmed a realistic "dream" the prior night that involved her monster form rampaging through Tokyo. Kuroe struggles and is dismissive of the information, and worries that Arata will not accept her for what she is (both human and monster form).

Kuroe Akaishi (赤石 黒絵) Voiced by: Hikari Senga (Japanese); Nia Celeste (English) The protagonist of the story, Kuroe has been suffering from a mysterious illness for at least sixteen years that causes abnormal body growth and disfigurement. This has led Kuroe to become an outcast feeling that nobody could accept someone like her. While Kuroe does not remember her past she tries her best to live a normal life in the present. She is surprised when Arata decides to date her and tries to hide her transformations from him whenever she can. Kuroe also has a pet dog named "Jumbo King". Arata Minami (南 新汰) Voiced by: Daishi Kajita (Japanese); Jacob Hopkins (English) Arata is a popular guy in Kuroe's school who starts getting model offerings. He takes interest in Kuroe, revealing that he too wants to be out of the spotlight, and lost a lot of weight to become the person he is known as. This quickly irritates the other jealous school girls crushing on him who cannot understand what he sees in Kuroe. Arata does not know that she is secretly a Kaiju which causes misunderstandings to happen. Rinko Akaishi (赤石 凜子) Voiced by: Kotono Mitsuishi (Japanese); Luci Christian (English) Kuroe's devoted mother, Rinko is shown to be there for her daughter against judgmental people knowing full well that she is a Kaiju. Rinko is also a former biologist who discovered the remains of a Kaiju and brought one of its eggs home with her. She then proceeded to raise the shape shifting baby Kaiju whom she named Kuroe as a human. Rinko is a big fan of the singer Mayumi Hamasaki, who is based on Ayumi Hamasaki. Koutarou Hibino (ひびの幸太郎) Voiced by: Katsuyuki Konishi (Japanese); Robert Mccollum (English) Koutarou is Rinko's former colleague when they were traveling biologists. He was with Rinko when they found a Kaiju skeleton and watched as Rinko decided to take home an egg vowing him to secrecy. While he does not approve of how Rinko raised Kuroe he acts like a protective uncle to her which causes Arata at one point to mistake him for a boyfriend. Koutarou has since started working for the Japanese government which has alarmed Rinko who just wants Kuroe and her newly hatched sibling to be happy. Manatsu Tomosato (友里真夏) Voiced by: Akira Sekine (Japanese); Megan Shipman (English) Manatsu is depicted as a wealthy girl who has a romantic obsession for the Kaiju. She attends the same school as Kuroe where the two become best friends, while not knowing that her object of desire is in fact Kuroe. Manatsu has a habit of dressing up as a butterfly (inspired by Mothra) in order to get the Kaiju to "stomp her flat" whenever it shows up. Raimu "Rairi" Kouno (河野ライム) Voiced by: Haruka Shiraishi (Japanese); Giovannie Cruz (English) The most "popular" girl in Kuroe's school, Rairi is shown to be heavily into makeup. She becomes friends with Kuroe and the two form a trusting bond when she helps her gain confidence in herself. Kuroe later learns that Rairi has also been keeping a secret about the way she really looks.

Written by Spica Aoki, Kaiju Girl Caramelise was first serialized in the monthly seinen magazine Monthly Comic Alive on February 27, 2018. The author had previous works serialized in magazines aimed towards girls (shōjo), so she was worried when a male-targeted (seinen) magazine picked up her series. Aoki thought she would have to make the series aimed more towards guys, until her editors advised her that "this story really works best as shōjo" even though it was in a seinen magazine. The first volume was published by Media Factory on June 23, 2018, with ten volumes released as of July 22, 2026. The series was also released in ebook format on Kadokawa's Comic Walker website. On November 18, 2018, North American publisher Yen Press announced at Anime NYC that they had licensed the series, with the first English language volume released on June 25, 2019.
