Sylin is a vagabond that travels the world and fights monsters, believing he is doing good for the world. Beyond that...his other motives don't matter as long as people benefit from his actions. His life falls into a cycle of fighting, receiving fleeting gratitude, and moving on to the next monster. He's content with it until Ash rudely storms into his life and refuses to leave. He reluctantly allows Ash to accompany him, though he regrets it the second he agrees. Oh, and they make crepes.
