English Title: OZAKA The Sword of Etheria or Chains of Power. One of those weird "stylish" action games with the added element of friendly "helper" NPCs that you can order around. Produced by the same guys at Konami who did... *shudder*... NanoBreaker, which probably explains why it never saw a US release.
Japanese Title: オズ
Publisher / Developer: Konami
Released: Jun. 30, 2005

Another one that seems interesting, but I haven't had a chance to really try it out at all. Will update this should that ever come to pass.
