Sukeban Deka II: Shoujo Tekkamen Densetsu

We take on the role of a schoolgirl codenamed "Saki Asamiya" who works for the government and fights crime with the help of a metal yo-yo. The game features elements of many genres. When exploring the school the game resembles a quest, when fighting enemies and bosses - street fights, and when walking through mazes - we see everything as if from the heroine's eyes (like in Phantasy Star series).
