Wasn't the most interesting chapter, but set up a lot of things.

I almost feel sorry for Natsumi, getting dragged into such an important role.
Yeah, it would be tough and dangerous for her >_< She punched Katarou in the face when he said "Yeah, I know I didn't think Natsumi-Neechan would ever have a chance in her life to be a main character..." :P
I loved seeing Sayo this chapter, her expressions were cute and funny :)
