Airship - Bridge
This is your second time onboard the Airship (Fahrenheit). The first time you see the ship is after the team escapes from Home. Check out the first Airship walkthrough section for more details.
Walk to the back of the Airship to find Yuna and Kimahri staring out the window. Speak to Yuna to continue the story.
Airship - Cabin
Yuna will attempt to apologize to Tidus for not knowing what to do, now that they don’t have Yevon’s teachings, and Kimahri will tell her not to apologize. Kimahri will explain that they should seek out Mika for more information.
There is another short cutscene that takes place when you return to the Bridge. Wakka, Rikku and Lulu will explain that they should use the Hymn of the Fayth to make Sin docile and to draw Sin close.
Speak to Cid and you will now be able to fly the Airship to any of the previous locations you had visited using the “NavMap”. Choose to travel to the Highbridge in Bevelle to speak with Maester Mika.
Approach the guards to continue the story. They will attempt to prevent the entire team from entering.
Shelinda will interject to prevent any fighting. She will then help the team to get in to Bevelle and will arrange an audience with Maester Mika.
Mika will chastise the team for defeating Yunalesca explaining that Spira has now lost its only hope. He will explain that Yu Yevon, the true enemy of Spira, uses Sin as its armor to wreak havoc on the people of Spira. Rather than stick around and fight, Maester Mika will disappear.
Finally, Yuna and Tidus will have a conversation with the Fayth about how to defeat Sin for the last time.
Speak to Cid and select the “Sin” option that now appears on the NavMap. This will initiate a short cinematic that involves all of Spira singing the Hymn of the Fayth and summoning Sin.
