Titles, an irrefutable necessity for any Dreamer. Only one word could do justice in describing it, advantage.
Unlike Skills and Items which targeted only a particular aspect of Dreamer. The Titles improved a Dreamer's capabilities in its entirety. There was neither limit on their equipment nor there was an issue of being Passive or Active. And that's why every Title was a prized possession of any Dreamer.
