Mysterious Sigil

""Now it's time to sleep forever.""

- Roen Yuia sacrifice her soul to activate the sigil.

Mysterious Sigil, this sigil is an inscribed or painted symbol that was once used by the Slayer White as a last resort to survive after he was defeated by a Zahard's Princess.

History
At some point, Sachi Faker found a note in Hoaqin's Spell Book which seems to be written by Hoaqin himself when he was still a Legendary FUG Slayer "White". ""I can no longer support this body. We shall split my body into five parts through this sigil, and leave four of the clones on the Hell Train for resurrection in the future. The Spells will be complete when I return, and I shall regain my whole power. But if even one of other spirit mingles into the sigil, the spell will fail and our souls will be sealed in the train forever. Therefore we shall trick the people on the train into killing each other.""

- Sachi Faker said what was in the note.

According to the note, the High Ranker Legendary FUG Slayer White had to split his body into five through this sigil because he can no longer support White's main body as a whole after his defeat to a princess. He then leave his four clones (his siblings Vicente, David, Anna, Albelda) on the Hell Train in order to ensure his resurrection as Slayer White again in the future. This sigil has a high risk, because if one of their spirit mingles into this sigil, the resurrection process will stop and thus White can't be resurrected.
