The Hand of Arlen is destroyed by FUG. Wangnan's team rescues Khun from the rubble, who explain that the long-haired man he saw is FUG Slayer Candidate Jue Viole Grace. While contemplating recent events, Khun encounters a familiar face...

Khun learns the truth from Hwaryun and decides to join Wangnan's team in the Workshop Battle. Meanwhile, Bam remains on Team FUG as Viole.

Unaware that FUG agent Viole is actually Bam, Endorsi Jahad attempts to capture him. Meanwhile, Team Shibisu launches a surprise attack on the hotel where Team FUG is staying and Wangnan and Team Khun face off against Chang and Quaetro.

The participants that acquired boarding passes enjoy a moment’s rest aboard the Archimedes. Khun is reunited with Rak on the floating ship. With their determination to take back Viole (Bam) from FUG, the “Flag” Workshop Battle finally begins!

The results of the individual tournament pit the two winning teams, Team Mad Dog and Team FUG, against each other in the Workshop Battle, while the losing teams advance to the training tournament. As their respective battles begin, Khun and Wangnan begin summoning their teammates.

Viole is sent to the bottom by Beta where the Thorn can be found. Reflejo appears before the massive Thorn to reveal the truth to Viole. Meanwhile, Team Khun is reunited with Team Shibisu, and they learn FUG’s true goal hidden within the Workshop Battle...

Viole (Bam), Khun, and Rak, who once thought each other dead, are reunited. Khun’s team makes an enemy of FUG and the Workshop, but at the suggestion of former 2nd Floor Test Admin Lero Ro, who has been secretly working to help Viole escape, they decide to leave the arena with the losers before the final begins. Reflejo uses the dying Hwaryun as a hostage to force Viole into a final confrontation.

While Reflejo, Viole (Bam), Khun, and Rak are engaged in their final showdown, FUG and the Workshop attempt to pour a solution capable of melting everything into the area... Lero Ro and Endorsi rush to their three companions in order to save them, but FUG Rankers and Team Mad Dog stand in their way! Will Viole and the others be able to escape safely?!

Reflejo is brought to the brink of death using the unleashed power of the Thorn. Viole (Bam) finds himself in a difficult position. But thanks to quick thinking from Khun and Rak and Endorsi’s Bongbong, they successfully escape. Their companions gather one after another and all leave the arena on the Wolhaiksong floating ship as the turbulent Workshop Battle finally comes to a close...
