Kairu
A 'Broken Angel Kairu' is like a human who got hit by a cheese grater and then stepped on by a cow. You can see the insides of their brain.
'I'm a broken angel Kairu now!', A guy with cheese coming out of his ears.
'You broke my angel Kairu!', A girl holding a cheese grater and crying.
'Kairu, you're like a cheese wheel!', A man who just got hit by a cheese grater.
