In the last room, the battle between Allen and Tyki Mikk begins, while Road tells Lavi to play with her if he wants to win the freedom of Lenalee and Chaozii.

The difference in power between Allen and Tyki is so great that Tyki easily knocks Allen down. Meanwhile, Lavi suffers and faces illusions in a dream created by Road.

Amidst great crisis, Allen's synchronization with his Innocence becomes stronger than ever, which results in his left arm turning into a large sword.

Lavi is trapped in the world of dreams created by Road. There, he's attacked by the people at the Black Order, including Lenalee and the other Exorcists.

While being burned by his own attack, Lavi asks his illusion for what purpose Bookmen exist and why wars never disappear from the human world.

The Noah within Tyki Mikk was supposed to have been destroyed by Allen; however, he has transformed into a dreadful figure and starts attacking Allen and the others.

After transforming, Tyki is completely in a different league from Allen and Lavi; however, they continue to fight against him. Then someone unexpected appears to rescue them.

The Millennium Earl says nothing can be done now that the "heart" of the ark has been transferred to the new ark, but Cross has other ideas.

When Allen comes upon a piano in The Fourteenth's secret room, he suddenly starts hearing a song in his head and, much to his own surprise, finds himself playing it.

After the ark returns to its original shape, Allen and the others go back to Edo, to the Asian Branch, and finally, to the Order's headquarters, where they are joyously welcomed back by the Order's staff.
