Die
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.
Picture someone else riding a scooter with an axe in their fingertips. That's so dangerous! One bump, one bad turn, and that axe slips and they'll die.

None
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. Wait, no! It shatters.
Your holy blue saber died for you. It saved you from certain death and now it died. After all you've been through together. All 60 levels. This is the end.
