65 million years ago
Venus Chan was busy on her new phone when a tennis ball bounced in front of her and over her head, she didn't pay any attention though, another ball bounced to the side of her, she gave a sigh but didn't move, yet another ball flew past her head, almost clipping her ear and causing her hair to blow about, Venus Chan looked up from her phone, on the other side of the net was Earth Chan, holding a tennis racket in one hand and a tennis ball in another. "Do you mind?" Venus Chan yelled. Earth Chan bounced the ball a couple of times.
"C'mon Venus Chan, Sunsei said that we were supposed to play tennis, can't you at least take your eyes from your phone and at least take part in the lesson?" Earth Chan served the ball, only this time Venus Chan moved forward slightly and hit the ball with everything she had.
Meanwhile back on earth
A triceratops was busy munching on some vegetation when it heard a noise from up above and looked up, heading towards the earth in the distance was a giant asteroid…
Meanwhile back at school
Earth Chan was lying on the floor, unconscious and with a large lump on the side of her head. Sunsei was busy trying to administer first aid to the poor planet, while Mars Chan was glaring daggers at Venus Chan, who was looking away from the scene with her arms folded, pretending that she didn't care, but rather worried about the consequences to come.
