- Sephiroth recruited Du Feld, Dorag Pierrot, Giberson, and Umit into his Company, then returned to Luluka Island and helped defeat the Phoenix Pirates while saving Steel Bone Kong and other Marines.
- After testing a drug made from Brook’s blood, Sephiroth’s soul nearly entered reincarnation, but he returned to his body and traveled through time to save his younger self and Hancock from Captain Peter.
- Sephiroth returned to Sabaody Archipelago and renewed his alliance with the four Company leaders before traveling to Nine Serpent Island to reunite with Hancock and give her and her sisters Pure Gold rings.
