To make this a bit more fun, I'm going to let one of you guys setup the manga criteria for the next time we do this, which I assume will be a couple of weeks or maybe a month from now.

The first one to send me a pm with the answer to this question will be the person.

The question is:

What anime am I currently thinking of?
This anime I consider it to be one of my top 5 of all time, and it's close to being a favorite (it's not my favorite). It's not that well known, and it's underrated in my opinion. One hint, I've made a review for this series, so I recommend checking the "30 Second Anime Review" thread. There are many series in there that I claim that can be my favorite or the best that I've seen, so go read the reviews carefully and choose the one that best matches the vague description I gave.

I know it's very vague, but it should be fairly easy to find. One attempt per person. Go to it.
