A teen, Nanana, who was killed, is chained to a single room in an apartment complex for a school. She was part of a group that hunted down treasures that each had a special power and weakness. Only "Adventure Club" (whose sole purpose is to continue hunting down the treasures) members are allowed to live there with her. Juugo, who has many personal problems of his own, is enrolled at the school and is assigned that particular room. At first, their relationship was rather shaky, and really was only help together by the fact that she was a cute roommate. But, as the series progresses, you see their relationship expand, and Juugo puts his ego aside to help Nanana. Throw some villains, a master detective, and a few secret organizations (as well as other characters) into the fray, it makes for a very entertaining series.
Not to spoil the series, the story is very good and pretty unique. It's sometimes hard to incorporate a "ghost" character into a series, but I feel as if this series did it very well. There is a ton of action, some romance, puzzles, a good amount of comedy, and even a tad bit of fanservice in there for you fanservice junkies.
The art and sound are very solid. No real flaws. The soundtrack used is very enjoyable and fits the series very well. The animation style is slightly unique, and all the characters are crisply animated.
The characters are very well developed for the most part. You don't get a ton of inter-character relationships until the later episodes. And at some points, you are left wondering what the connection is. But rest assured, you will get some answers. I like that romance wasn't a theme that was being forced down my throat, and the fanservice was not a major focal point of the series.
The negatives- I was slightly confused at times with the relationships between some of the characters, given not much back story or flashbacks. Also, the length of the series. 11 episodes makes it slightly shorter, and may have caused the series to be rushed a tad bit.
Overall, the series is extremely enjoyable and entertaining. It has very few negatives, and if you are looking for a series that has action, comedic moments, and not a typical run of the mill plot, you should definitely give this series a watch!
