Turmeric is a member of CEDEF, and therefore is a subordinate of Iemitsu Sawada. He fought alongside Oregano and Lal Mirch when CEDEF invaded Vongola HQ so Iemitsu could talk to and, if necessary, rescue the Vongola Boss. He read the censored Mosca plans and knew that the Italian Military sold some of their weapon plans to the Mafia, and discovered that they sent one to the Varia. After they met back up with Iemitsu, the fake Vongola IX gave them enough information to realize that the real Vongola IX was in fact inside the Gola Mosca that was sent to the Varia. Unfortunately they were too late to stop the Cloud Guardian battle. (Source: reborn.wikia.com)
