Sepira took the Mare Rings, a fraction of the Tri-ni-sette, and founded the Giglio Nero. The rings were passed down to her successors, with the exception of the Sky Mare Ring which ended up with the Cervello.
Three months after Uni took over the role as the Famiglia's Boss, Genkishi was defeated by Squalo. There was a bargain that Genkishi made up so that the Gesso Famiglia and the Giglio Nero Famiglia could join. The deal was that if Genkishi could defeat Squalo, the Gesso would not bother the Giglio Nero for five years. Genkishi didn't try to win; he wanted the two Famiglias to merge because he was secret loyal to Byakuran ever since the latter saved his life from an illness.
To prevent any more violence between the two Famiglias, Uni met up with Byakuran and the Gesso Famiglia for a meeting, taking with her four of the five Mare Ring Guardians: Gamma (Lightning), Nigella Beabankul (Cloud), and two unnamed others.
After a private meeting between Uni and Byakuran, the two famiglias merged to become the Millefiore as a result of Byakuran drugging Uni-- the drug dulling her heart. The Giglio Nero became the Black Spell faction of the Millefiore. Uni became the Black Spell leader, Genkishi and Gamma became Fake Funeral Wreaths, and Gamma, Nigella, and at least one of the unnamed former Mare Ring holders became Squad leaders.
Giglio Nero Famiglia
The Power of Divination runs through the Giglio Nero family's bloodline. This power gives the Giglio Nero Boss a superior ability to foresee or predict the future. This power is even stronger with the Orange Arcobaleno Pacifier; however, over time, the power starts to get weaker due to the Arcobaleno curse, causing the Boss to have a short lifespan which doesn't allow for growth of the power.
Giglio Nero base
A building belonging to the Giglio Nero Famiglia, located in a wooded area. It appears to be their main base of operations at least in the three months Aria died in and afterward during Uni's time as Decima.
The Giglio Nero Famiglia's west temple. It was here that the Six Funeral Wreaths and Byakuran joined up with Nosaru, Tazaru, and Gamma to become Uni's representatives for the Representative Battle of the Rainbow.
- Giglio Nero means "black lily" in Italian.
- The symbol of the Giglio Nero appears to be based off the original Sky stone of Tri-ni-sette.
