I am looking for the title of an anime I watched a while back. I know it is a longshot asking here but...
It was about an earth boy who was accidentally killed by an alien girl in some sort of mech robot when it landed on top of him when he was running through a park. Some how that mech robot brought him back to life and he became its pilot. That is all I remember. I am wanting to watch it again but cannot find it.
Anyone know the title?
