Explain the opening to me, because I can't read Japanese.
The main character gets up. Tries to leave his house. His mom makes him get dressed so that he can leave now. Talk to some old guy. Walk over, where a friend shows you how to kick a dinosaur. o_0
After a few kicks of the T-Rex that likes to play dead (actually, I think it's also a dash but it's like a kick when you do it right next to something), a big ant comes up. Then you fight the ant?
Then aliens attack? What?
Actually don't explain it, it's funnier this way. *kicks dinosaurs*
