Well I think Hyuuga Hinata-chan from the Original NARUTO -ナルト- fits that 説明 because she is very shy for most of the series especially when it comes to NARUTO -ナルト- sometimes..
Shino Aburame - Naruto He's kinda shy, a little arrogant an very much a loner, guess not many people are a ファン of the bugs XD I 愛 Shino! He's one of my favorites!
