In the same vein as the Fiasse picture posted a few days ago. For further reference, Nanoha shares a minor spotlight in the series Triangle Heart, whereas her sister and brother Miyuki and Kyoya are depicted as the main characters. This role is reversed in the Magical Girl series, but they still retain many similarities (personality and otherwise) despite the complete change of scenario.

Well, in the MSLN game her brother still plays a major role.
