Dreadshell is the second in command of a dark magic syndicate known as the “Black Rose”, He would think that he is worthy of claiming the title of leader after the “presumed death” of Rosalia the Witch after Gepard Phalanx killed her, but he didn’t claim the title, this makes him think that the leaders he serves are “wimps” or “morons” because they fight and end up arrested or dead. Which is why he wants to take over the Syndicate for himself.
