In a nutshell Nanoha is a story that centers around Takamachi Nanoha, an ordinary girl who one day meets a talking ferret who gives her the intelligent device Raising/Raging Heart as a result of unexpected circumstances making her a mahou shoujo.
I could go into detail but if you don't already know the plot go see it for yourself. Lyrical Nanoha is a unique mahou shoujo series that mixes emotion and explosive battles and even has tear jerking scenes in each season.
This will act as the the official Colorless Nanoha thread which can be used for anything. Be it findings you want to show or any inquiries you may have.
I will at times increase your knowledge of the series with things that aren't even mentioned in the anime itself but in other media such as games, manga or even drama cds.
Let the befriending begin!!
