Coulomb Family

The Coulomb Family was a family based in Lucifenia which became a part of the Venomania Bloodline after a member had a child with a member of the Octo Family.

Early History
Originally settled in Lucifenia, the only known family member at the time, Nagisa Coulomb, became involved in the Lucifenian Revolution by supplying weapons to the revolutionaries. At some point she began an affair with the Venom Mercenaries' leader, Gast Venom and became pregnant by him, but Gast during the revolution died before the son was born.

Cursed Blood
Nagisa's son went on to marry and have a daughter, said daughter started working as a prostitute in Asmodean. Eventually she became pregnant by a costumer and gave birth to a son Gatt Coulomb. The woman raised him on her own, facing discrimination together due to their relation to Gast.

Gatt went on to serve in the military and became a lieutenant general. He later allied himself with Julia Abelard and became part of her criminal organization Père Noël as Sixth Venom. Gatt served Julia and completed many assasinations under her orders. Eventually, he was tasked with killing the mage Elluka Clockworker and was trusted with Grim the End to do so, however Elluka electrocuted him and tied him to a tree, leaving him to become arrested.
