"Wait... but..." Shiro took a few steps after the female, but she was gone. He simply stood there for a while, rather confused and unsure of what to do. He sighed and headed for the room they usually let him play with his katana in, dragging his hand along the wall so he could keep track of where he was and to make sure he didn't run into anything. As he entered the room, he quickly found a sheathed katana on a table, as well as the spherical robot that followed him around and healed him if he got hurt "playing" with other experiments. He tapped it a few times in an attempt to wake it up and unsheathed his katana, slashing at the air rapidly several times and smiling a bit before sheathing it again.
