Love Hinata. Its hard to get her out of my groups. I keep looking for new teams without her, but her acupuncture chase is so good. Neji can do it too but his seems to be harder to find combos for him, and his evade isn't all that reliable. Hinata's evade is only available once every 3 turns, but that first turn is usually the most important for controlling a battle.

its at the top of the first post. elite instances. level 20, 30 and 50 each have a stage. you also get 30 fragments for completing the level 30 elite instances. and you can get them from the ranked battle shop for 500 points per 5 fragments.
