Reincarnated as Dragon and Butter-like Kaiju, two best friends must survive battles between the world's most powerful creatures. The couple will face many challenges in this new environment and learn to overcome their fears of being alone after losing all they once cherished. Only two things are certain: true friendship has no end. And if your gender-fluid best friend was transformed into a female Kaiju who loves it, by the way, you learn not to question it—even if she wanted to be your wife.
