Alice Kara Mahou

Overview

When Alice was little, her late mother foresaw that when Alice turns 13, an event will change her life forever. Now a spirited 13 year old, Alice plays and bickers with her friends, has a boy she's interested in and, like her mom, loves to foretell the future using Tarot cards. One day, Alice is watching the stars with her classmates when a meteor shower passes. Only, it's not "stars" that are falling, but magic jewels! These gems can be absorbed by human bodies, causing various side effects, most of them not pleasant. And so Alice, armed with a key to open human hearts and a magical bunny for a sidekick, sets out to extract all the gems before they cause too much damage, healing hearts along the way.
