The Committee (委員会 Īnkai) are the heads of Sector Seven. They are an apparent reason for the conflict between Sector Seven and the Novus Orbis Librarium due to their detest for the latter. It's unknown if Kokonoe Mercury was a member.
The Committee are first shown in the BlazBlue: Continuum Shift II story That which is inherited. Around 15-20 of the Committee were present at the Sector Seven Board Meeting and later ordered Relius Clover to look at the Deus Machina: Nirvana that they retrieved during the Phenomena Weapon Dispossession Operation; another event that they orchestrated. The Committee's relationship with Relius Clover is largely ambiguous.
During BlazBlue: Chronophantasma, the Committee released Azrael from stasis after a telephone call from Relius. They gave Azrael the orders to take down Kokonoe and Iron Tager, and to confiscate Ragna the Bloodedge's Azure Grimoire. They put multiple restraints on the Mad Dog so he wouldn't go berserk.
