What is the Pair ingredient in Toriko?
Pair is the pair of testicles of a Ballboon.

Monkey King Bambina's Pair is the hardest to get, and also the most delicious because it is fresh off the monkey. The Ballboons hang their Pairs from the Birth Cry Tree as a mating ritual.

Retrieving Pair from the Birth Cry Tree can be accomplished with 2 means: Eating someone of similar power to yourself, or having a Ballboon pluck them off the tree.

Originally, Pair's capture method was much much different, but one of Bambina's ancestors ate the original source of Pair, and this drastically altered its obtaining method
