As Yui's sniping concluded, she noticed her barricade was being hit. Apparently, someone wanted in. Yui had anticipated this. She prepared her last surprise from her guitar case... a Claymore. She set up the device by the door, and hid behind a desk, pointed toward the door. As the barricade fell down, and the door flew open, Yui covered her ears and closed her eyes, anticipating the inevitable flash bang grenade. It went off, and the pointman rushed in, tripping the Claymore. This left a rather large hole in the wall, giving Yui the ability to rise up and fire rounds at the shocked survivors of the SWAT team. With just a little preparation, Yui, a fifteen year old girl, was able to kill off a team of specially trained assault police forces. When the dust cleared, there was only one figure standing outside the door.
