The Bubblegum Zone/YMMV

Main work here
 * Complete Monster: Hollister et al.
 * Gary Stu: Only very early on.
 * A pretty debatable statement, as he's still doing things Sylia disapproves of and getting away with it for most of the story. In a lot of ways by the halfway point he's gotten worse, as he's actively asserting his superiority rather than it merely happening.
 * Growing the Beard: While the beginning isn't by any means particularly bad, the story becomes better and better once you get halfway through the original OVAs, especially when the original material begins appearing.
 * High Octane Nightmare Fuel: What Hollister and friends want to do with Sylvie and Anri.
