If you ride a scooter with your fingers around an axe you're going to die. I mean, probably. There's a 99% chance you'll die.
You slip. The axe collides with your face. You die. But... wait! There's a bright, blue glow and suddenly you're un-dead. You watch in slow motion as your holy blue saber (せい) brings you back to life and takes the hit from the axe instead.
