Between the stress of hiding her relationship with Minami from the fans of said "Kaiju Prince" and then encountering a strange man at the park who accused her of being a kaiju, Kuroe's at her wits end! Just how much longer can she last before she needs to transform again? Meanwhile, her mom's left on a trip to the island of Kuroe's birth. But what secrets remained hidden on the island so many years ago...?

The last thing Kuroe wants is to cause trouble for the residents of Tokyo, but with school heartthrob Arata in the mix, the city's fate is looking a bit shaky! What's a lovestruck Godzilla gotta do for a chance at a normal love life?!

Suffering from a rare, incurable illness that causes frightening changes to her body whenever she gets worked up, loner Kuroe Akaishi spends her high school days avoiding her classmates, especially class idol, Arata Minami, and his groupies. But when Arata starts making her heart skip a beat with irritating regularity, Kuroe soon discovers that her illness actually has a big--make that, MONSTER--secret! Romance turns her into Love-zilla...literally!

Is it really over? After Kuroe and Minami had a massive argument where she kinda-sorta broke up with him, she's been a total emotional wreck. However, when an Unidentified Flying Object, traveling at high speeds appears in front of Kuroe, it's up to her to save Tokyo! But distracted as she is, she soon finds herself at the mercy of the other kaiju. Will Minami step up to save the day-or turn his back on the girl he once loved...?

As if magically transforming when she gets nervous weren't enough, high school girl Kuroe also has to survive the twists and turns class heartthrob Arata causes through their...acquaintance? As the new semester approaches, a new face brings a mountain of new problems along...
