This was literally the biggest waste of time I've ever spent. Spoiler-free, here's my thoughts.

Story - 5 (At best)
When starting out, you realize the character is already in a terrible situation. As with most revenge types, you're interested in how she's going to...well...get revenge. It starts out with minor characters who didn't really do too much getting in trouble. As you progress to the real antagonists, however, it slowly becomes more of a forgive fest than revenge. Which in the case of some characters, don't need to be forgiven but should of been the actual targets of revenge. It's like the author decided to completely change their characters in the middle of a chapter to be good guys. Too many "surprise twists" and hidden villains to actually progress with our main characters. The end was obviously rushed. The author probably realized they messed up any character development they did and wanted it to end.

Art - 7 (Actually isn't that bad)
The art was really clean and well done. It was stylized perfectly for a dark setting like a revenge story. The artist knew how to get expressions across really well.

Character - 5 (Read story section for my issue)
As I've mentioned above, the characters are all over the place that you end up hating them all. It becomes a chore to actually try and care about these characters. When you have characters go from rapist to secret protector, you know the author was just pulling out whatever he could to try and finish the story.

Enjoyment - 5 (I wanted it to end early)
I enjoyed it at first because she was truly planning on revenge. But after the first victim realized that the sword on the cover was just for show. It picks up the pace later on, but at that point most characters end up changing their personalities completely. Too much changes to actually enjoy it.

Overall - 5
What else can I say. If you're very bored and have bounds of money to just spend, then sure buy this and go on a mediocre journey. You can do better though. It isn't even revenge most of the book, as stated earlier. With all that said, I regret this book.
