I do like the fan service shots they put in this anime
But back to the anime itself. Quite a few interesting things happening in this anime with the whole mind switching thing and the huge "Alone" vehicle thing destroying jets with skilled pilots without trouble.
The Gramps character is going to be favoured by a lot of people, he's certainly in my "Pay attention to the things he does" category because of the humorous yet interesting things he does
The flashback showed how their mother was hospitalized and her fear of heights, or that's what i'm assuming at least
I wonder how everything ended up like that with them hanging on for life. Hopefully more flashbacks will happen.
Overall I liked the first episode, it was interesting
