Proof of the Brave Men of the Heavens

Luca: What a mouthful! Who is a brave man if he doesn't save the world once? Luca sets out on a journey to save the world. Of course, first of all, you have to fill your stomach. … However, as soon as he went out, Luka was stopped. Proof of the Brave: Found it! The legendary hero who saved the world! (Although it was a previous life) Luca: Just like that, a certain brave man who didn't want to reveal his origins chose me. He wanted to take me to the world of brave men and guide me to save more worlds. (The main world is a universe that integrates all kinds of braves, and it is tentatively planned to travel through Harry Potter, Naruto...)
