Kaiju No. 8 (also known as Monster #8) is a fantastic series drawn by mangaka Naoya Matsumoto all about the Japanese Defense Force's fight against the ever-present Kaiju threat in a fictional world. The term 'Kaiju' essentially translates to 'Monster' in English (hence the two manga titles) and represents a whole sub-genre of media in Japanese film, manga, and anime all about giant monsters duking it out.
