Onechanbara: Bikini Zombie Slayers' main characters, Aya and Saki -- perhaps a little too much, in terms of modesty! Tamsoft's embarrassing action-horror game features two more playable characters, both of whom have their own unique idea of appropriate zombie hunting attire.
Reiko is one of many clones of the "Original Reiko" created by some unspecified agency of SCIENCE!! She is ordered to take a sample of Aya and Saki's blood (which apparently is the cause of their occasional bouts of blinding rage). Misery also wants the sisters' blood, but to make herself stronger. Our suggestion for increasing combat effectiveness: the crazy chain sword is a good start, but we'd bring some shoes into battle.
