A human meat shield. They punch you until you’re sore, but you can’t even hit them.

I’m an obsidian feather. They hit me until I’m dizzy, and I still can’t punch back.

My sister’s an obsidian feather. She took all my punches and still didn’t hit me once.

I’m the obsidian feather of the class. They all punched me, I just took it like a dog.
