Eensy-Weensy Monster

Nanoha Satsuki is your average high school student. OK grades, kinda cute, kinda short - Nanoha's most notable quality is that her best friends are both total overachieving babes. But when Nanoha runs into Hazuki Tokiwa, the gorgeous prince of the school, her gentle disposition disappears and she turns into a total monster! And Hazuki is more than happy to be a jerk right back at her. Thus begins a hilarious love battle!
