Teach reached Salem Town, a settlement built on a Kraken, and persuaded Circe to send him to Colchis for help against Drake. Meanwhile, Rin sensed a dangerous presence in the waters ahead and stopped her fleet, leaving her increasingly tired and uneasy as a frigatebird watched Salem at night.

• Drake sailed with Rin’s Queen Fleet toward Teach, while Teach’s fleet approached Salem Town and was admitted by the Kraken beneath the town.

Queen of Sheba appeared before Rin’s fleet, and Rin attacked her after mistakenly believing she was Solomon’s wife and that Solomon controlled Gae Dearg. Doctor Roman cleared up the misunderstanding by explaining that he had once been Solomon, but his wish to become ordinary had erased Solomon from that timeline; Queen of Sheba then asked Rin to bring him to Salem.

• Circe asked Rin to protect Salem and avoid attacking it, but Rin refused because she doubted Circe's account and wanted the Singularity corrected.

• Rin and Circe unleashed their attacks, but Lovecraft arrived and halted the fight.

• Sakura convinced Lovecraft that Chaldea could face a Great Old One by citing its past victories and Crimson Moon’s power, prompting Lovecraft to give them his research and seal information.
• Sheba looked after Little Abby while Lovecraft attended to the guests, and Little Abby suspected he was lying when he left, privately longing for her father.

• Rin, Fujino, Servant Kiritsugu, and Lovecraft found a hidden teleportation array beneath the floorboards of a church outside Salem Town, leading to underwater R’lyeh.

Rin led Chaldea into R'lyeh to remove the seals and awaken Cthulhu, but at the first tower she discovered that Lovecraft was an incarnation of Yog-Sothoth. After the first seal broke and the barrier weakened, Rin rejoined the group and revealed the truth, leaving them unsure whether they had walked into a trap.

• Rin abandoned the plan to use the priests for a Divine Descent and led Chaldea’s strongest fighters into R'lyeh while Da Vinci, Fujimaru, Gudako, Illya, Circe, and the Gorgon Sisters stayed behind.
• Rin surveyed R'lyeh from above, saw that its thirteen towers formed a huge magecraft circle, and learned from Lovecraft that the seals had to be released in order.
• At the first tower, Rin questioned Lovecraft about his changing attitude, and he revealed that Yog-Sothoth had transformed him after he encountered the Outer God as a child.
• Rin realized that the original Lovecraft had died at thirteen and that Yog-Sothoth had survived in his body and thoughts; then the first seal shattered, weakening R'lyeh’s barrier.
• Rin returned to the group alone, and after Touko helped her recover, she told everyone that Lovecraft was Yog-Sothoth’s incarnation, making them suspect the mission might be a trap.

Rin learned how Yog-Sothoth, the Demon God Pillar, and the Root had made her a pawn in the effort to free Cthulhu, while Chaldea pushed through R'lyeh's remaining seals. After the team stopped to rest amid relentless attacks, Rin found Fujino and Sakura still badly exhausted.

• Rin learned that the Demon God Pillar had accidentally made Cthulhu absorb the Holy Grail, allowing Manaka and Ryougi Shiki to seal Cthulhu using Type-Moon's power.

Rin and the Chaldea group reached the central structure in R'lyeh, but after searching it for hours they could not find Cthulhu's seal. Rin realized the true seal was R'lyeh's reflection in the sky, and she took off in fury after understanding how badly they had misjudged the mission.
