Nano-Nano Pudding

Nano-Nano Pudding was the third member of the Rune Angel Troupe, and piloted the Emblem Frame First Aider. She was a sentient human-shaped collection of nano-machines, and much like her adopted mother, Vanilla, could heal wounds using nano-machines. Her tail was in fact a collection of nano-machines used specifically for healing; occasionally, they would need to be replenished. Before joining the Angel Troupe, she underwent military training under Forte.
