Manga Protagonist Ideas

I'm trying my luck by constructing a Manga of my own. I have few ideas, and I'm just in the stage of creation at the moment. These two drawings are concept art I made of the protagonist. What's his name? I don't even know yet, I'm much better at drawing my characters than I am at naming them.

This is where I want you, the audience, to help me with. I want any of you to comment a thoughtful suggestion or name for this protagonist as long as its appropriate. So basically if any of you guys have a name or idea I can use for this character (even if it's a suggestion for the hair or clothes).

As for my own ideas on this protagonist, so far I have that he is a hunter of Monsters, and a collector of relics. He lives in a village constructed from the ancient remains of large boat. He's roughly 20 years old, and will embark on the journey of a life-time. If you ask, I'll try to give as much information as I can, but I'm still trying to formulate the characters, setting, and plot.

I do not have a prize for anyone who comes up with good ideas, but please help me with this.

P.S. If anyone has an idea for a title to my Manga, that would be helpful too.
