The Oneechamploo: The Oneechan Special Chapter

In this violent action game (updated from the original Oneechanbara), you control a scantily-clad girl who uses a katana to slice and dice zombies. In addition to Aya, who appeared in the original The Oneechamploo, you can also control the Simple series cover girl, Riho Mitaba. As you defeat zombies using gradually growing combo attacks, you find yourself covered in blood, building up a gauge along the way. Build the gauge up high enough and your character's speed increases, giving you added attack power.
