Zero

Zero is the main protagonist of Metanoia and  the avatar name of Nico when he plays the online game.

A Vagabond traveler is a mysterious individual who wanders from town to town claims not to be looking for trouble but always seem to find it.

Due to its shabby appearance; this is probably not the most popular character class among METANOIA gamers, but Nico affinity to it stems from the fact that the vagabond's strength lies being overlooked, underestimated, and having virtually nothing to lose, hence the name of Zero.
