Story 8/10
I really love this anime's premise because I'm hard-pressed to think of another anime like it.
Every episode (or few episodes) the characters find a new set of Ruins (a treasure location) where they have to get passed a complicated series of traps and solve a puzzle or two to get whatever particular treasure is hidden in these Ruins.
It's cool because first they have to find the Ruins, which could be anywhere on the island, and then after they find the Ruins is when the real fun begins. The traps they have to get past are actually deadly so you feel a real sense of danger when their getting through them. The puzzles, too, are very challenging and it's satisfying and fulfilling when they solve them.
The only complaint I have is that because they're is so few episodes you only get to see the characters beat two or three different Ruins in total.
Characters 7/10
The show has a lot of good characters and they all want the treasure for their own reasons, and they aren't afraid to step over each other to get it.
Juugo: I like Juugo because he has this determined, never-give-up, heroic kind of attitude that makes you want to cheer him on during the action scenes. Also, you learn more about his past later in the story like what the real reason he came to Nanae Island is.
Nanana: Nanana is your typical goofy, happy-go-lucky anime girl, but that's what I like about her; she brings a lot of humor to each episode and is a real joy to be around. However, Nanana only makes very brief appearance and is usually only in an episode for like three or four minutes before moving on.
Tensai: Tensai is my favorite character; Tensai's dream is to become a master detective and for her finding the Nanana's treasures is more about the challenge and proving her mystery-solving skills. I love how she doesn't care what other people think and acts like she lives in her own little world. Also. it amazes me how smart she is and how she always solves the puzzle before anyone else. Plus, there's this running joke where Tensai thinks of Juugo as her rival and Juugo just ignores her that's just hilarious to me.
Yukihime & Shuu: Yukihime & Shuu are a pair of thieves also after the treasure and I really like both of them, Shuu more than Yukihime, but the problem is they're only in three or four episodes which is really disappointing because they're such cool characters.
Ikusaba: Ikusaba only appears the last three episodes, but he's such a great villain I just had to comment on him. Ikusaba will do anything to get the treasure and will crush anyone that gets in his way. He sometimes has other people get the treasure for him, but he'll throw them away as soon as he no longer needs them. Also, he's sadistic and will laugh as he crushes your bones. I really wish he was in more episodes.
Others: The show has a few more characters like Isshin and Yuu, but their really isn't enough focus on them for me to say anything about them other than they also want the treasure.
Overall: Nanana's Buried Treasure is a good anime and was fun to watch, but really would've been better with a few more episodes. The characters could've developed more and it'd be fun to watch them have more adventures.
WARNING: I do have a few unanswered questions :
Why did all the treasure chests have "777" on them?
Who is Leprechaun (the person who hid the treasures)?
How come Yun lost her memory?
And what was with those after credit scenes in the last episode? Were they building up to Season 2?
