Hiiro no Kakera: Series (2012)

High school is hard enough without being a first-year transfer student - not to mention you're the Tamayori Princess successor who is supposed to fulfill a destiny you're completely unaware of...that doesn't seem like too much to bear! But that's exactly where we find Tamaki Kasuga when she is asked to come live in the country with her grandmother. Things start to get weird when mysterious dark forces and a gang of misfits called the Logos come after her. Luckily for Tamaki, she is suddenly surrounded by five handsome young men who come to her rescue and now act as her guardians! Because being a princess isn't easy, and she'll need all the help she can get in!
