Anyone know what anime this is?
I watched this anime 6 or 7 years ago but can't seem to remeber what it was called.
A black sphere covers tokyo and for all the people inside time stops and they assume the outside world was destroyed. A woman working for a government organization breaks into the sphere and runs into a boy who used to be her boyfriend but is now much younger then her due to being stuck in the sphere. They escape and must fight against a type of alien creatures. The boy also turns out to be an alien or something like that and has blue/green blood.
Parts of that may be wrong but generally that was the storyline would appreciate any help with finding the name of this.
