Hi there. Im looking for a anime movie with a guy that has a talis object on his hand, there's a pointy space ship in there what shoots their weapon from the two pointy ends. The story is they fighting aliens I think in green blobby spaceships. In the end what I remember they go through a tunnel what's comes into a world where the adults turn into kids. Vague discription but that what I remember as a kid lol. It's has a lot of action in it. Help me find it.

Also the city/world is covered by a sphere and soon people pass it they turn into kids again. Djjuggernaut200
