IP Rank

IP Rank (IP序列 IP Joretsu) is a ranking system based on the combined strength of the Promoter and Initiator.

Description
IP Ranking is an attribute published by the International Initiator Supervision Organization, otherwise known as IISO. It dictates the combined strength of an Initiator and a Promoter. Additionally, the ranks are based off on the number of killed Gastrea and battle achievements. Lower numbers such as those in the hundreds are consider extremely dangerous and strong combatants, whilst high numbers such as those in the one hundred thousands are consider low in strength.
