Dragon Across Ten Thousand Worlds: A Journey Through the Realms

[No Female Lead + Has a System + Devouring + Chuunibyou + Twisting the Plot While Causing Trouble + A Bit Unhinged in the Middle, Completely Mad by the End] A chuunibyou dragon with a System transmigrates through different worlds, grows stronger by devouring, and never grows up. Some of the worlds are obscure.

(The protagonist gets pretty unhinged later on, but he doesn't go completely crazy at other people, probably.) (See the author's note at the beginning for details.) [Very Important: Please read the author's notes! I may include images from the original manga.]

(Note: The worlds featured in this book may not be what you expect.)

[Important: The author's mental state is occasionally poor.]

Worlds so far: 1. Legendary Monster Universe, King of the Monsters

2. One Piece & Toriko (It's all about overpowered mechanics,)

3. ??? (Take a guess) (The overpowered mechanics are suppressed… But that's fine. Ordinary mechanics and ridiculous stats can handle everything.)

4.
