I don't know who to be more intimidated by...Sanae for that insane look? Reimu in general? Youmu is already a threat, OR THE FACT THAT MARISA HAS ALUCARD'S GLOVES?! Incoming Cromwell Invocation!
It should be noted, these are your heroes. You want a nice hero? Too bad, they're all dead. These are all that's left. You think these heroes are too crooked, too violent, too mercurial, too insane? Too bad! Remember, what's out there is even worse. And these heroes survived all that. If you want to live, just have... a little faith. And also get out of their way. That's important, too.
