Poppling

A Poppling (Romaji: Poppuringu; Kana: ポップリング) is a native and survivor of a popped Bubble.

Under normal circumstances, when a Bubble pops, everyone and everything within the Bubble is erased from Existence. As such, a supermajority of popplings are individuals who were not present within his or her Bubble when his or her Bubble popped.

However, once every Blue Moon, an individual is able to survive his or her Bubble's pop while he or she is within his or her Bubble. Such an individual is known to the ARI as a True Poppling (Romaji: Tōrū Poppuringu; Kana: トゥルー・ポップリング) and are viewed as a myth by a supermajority of the ARI's agents.

Notably, according to ARI folklore, all True Popplings are destined to avenge the pop of their native Bubble...
