The craze of light novels adapted into TVA will never fade away... Another light novel has been announced to be adapted into TVA and will be released in January next year, that is "Gun Emperor: Endless Fafnir".

"Infinite Fafnir" (Japanese: 銃皇無內のファフニール) is a Japanese light novel written by Tsukasa and illustrated by Riko Tsueeda, published by Kodansha Light Novel Bunko Publishing. The Traditional Chinese version is published by Tongli Publishing. The story tells that a monster called "dragon" suddenly appeared one day, causing the whole world to panic. The only one who can fight them is "D", who has the power to destroy dragons, and most of them are girls. As the only exception, the male protagonist Mononobe Yuu suddenly accepted a transfer order one day and came to Midgard. In addition to having to live in a school full of girls, he must also use the ability of "D" to fight against dragons.

In fact, for these adapted works, is the plot important?
