Bai Mo joined Jason’s quest for the Golden Fleece, challenged the gods’ designs, and fought alongside the Argonauts as they crossed dangerous lands and seas. After helping them escape Colchis with the fleece, he learned that Medea held his Thread of Fate, leaving Jason determined to protect the crew from being turned against one another.
Bai Mo defied the gods to return Medea to Colchis, then was cast from the mythological world after killing Poseidon and enduring Zeus’s lightning. After training with Oga, he arrived at Einzbern Castle and took Illya, Leyritt, and Sella with him toward Japan.
Bai Mo tried to protect Illya, Sakura, and the people of Fuyuki while confronting Francesca and the Holy Grail’s corruption. After saving Irisviel and destroying the Grail, he faced the arrival of Beelzebub, whose power overwhelmed the first attacks.
After defeating Beelzebub, Bai Mo left the Emiya Residence and became entangled with Shiki Ryougi, the Giant Shark Heavenly King, and Fujino Asagami. The arc ended with Bai Mo uncovering Araya Souren’s role in Fujino’s violence and preparing to investigate him further.
Bai Mo and his allies fought the system’s empowered Supreme Heavenly King as the world collapsed, and Bai Mo returned from death with a weak body and a new path to power. The survivors reached Supreme City, where Bai Mo’s attack opened its defenses and the Supreme Heavenly King called them to the amphitheater.
Bai Mo defeated the Supreme Heavenly King and sacrificed himself to give Shiki the power to restore the world, but was revived and began training to pursue a new ideal world. The arc ended with Bai Mo stranded in a parallel-world Japan, where a golden-haired woman mistook him for Roa and attacked.
Bai Mo helped Arcueid and Ciel confront Roa, whose defeat transferred his power to Altrouge and awakened Crimson Moon. After rescuing Misaki’s people, Bai Mo left to answer Crimson Moon’s invitation while Arcueid’s condition worsened.
Bai Mo defeated Crimson Moon, helped Arcueid survive her dangerous power, and found a route through time and parallel worlds. After returning to the Giant Shark Space, he challenged Giant Shark while Hell guided Crimson Moon toward a new path.
Bai Mo helped Uruk survive its crises, rescued Gilgamesh from the Underworld, and uncovered a scheme involving stolen divine authority and Demon God-nurturing soil. The trail led toward Eridu, where Oda Nobunaga and her followers had already set out.
Bai Mo protected Eridu from the World-Destroying Demon God, then returned to Uruk and entered Imaginary Number Space to investigate Tiamat’s prison. After defeating the Thirteenth Grand Protector and finding Tiamat with Manaka, Bai Mo entered her consciousness, where Tiamat’s breathing stopped and “Sajyou Manaka” opened her eyes.
Bai Mo escaped Tiamat’s dream, returned Ereshkigal to Uruk, and fought Enlil as the god tried to remake the world. After Enlil fell, the Thirteenth Grand Protector took control of the Heaven and Earth Demon God and faced Bai Mo in battle.
Bai Mo defeated the Thirteenth Grand Protector as Tiamat's arrival brought further battles with Enlil and Sajyou Manaka. Shiki took Bai Mo away to restore his life force, while Gilgamesh judged Gorgon, Kingu, and Sajyou Manaka in Uruk.
While recovering in Sengoku Japan, Bai Mo investigated Mochizuki Chiyome’s strange power and helped protect her clan during the conflict with Uesugi Kenshin. He uncovered Ashiya Dōman’s involvement and told Chiyome he wanted to retrieve her Primordial Spirit only after she died naturally, leaving her stunned.
Chiyome gained control of her cursed power, took revenge on Morotoki and the emperor, and negotiated a political settlement with Oda Nobunaga. Bai Mo closed his clinic and prepared to leave, but Arcueid arrived with news about the Ryougi Lataib and the cultivation manual.
Bai Mo rescued Olga Marie, reunited with Chaldea, and entered the Russian Lostbelt to help its stranded members. After battling Ivan and joining the resistance, he rescued Atalanta from a curse and turned his attention toward the Fantasy Tree near Yaga Moscow.
Bai Mo led the fight against Ivan the Terrible and Bai Wubian as Chaldea prepared to destroy the Lostbelt. After Ritsuka chose to reclaim Pan-Human History, Bai Mo began transferring the Lostbelt into Shiki’s system space, and the power engulfed him in flames.
Bai Mo survived absorbing the Fantasy Tree and helped rebuild life and Chaldea in the Russian Lostbelt. After entering Northern Europe with Ortlinde, he fought dragons and giants and reached Skadi’s realm, where Chaldea began to question the goddess’s identity.
Bai Mo defeated Hrungnir, allied with Skadi and Ophelia, and rescued his companions from a trap in Helheim. After learning Landao Tianwu was holding Valkyries and seeking Odin’s hidden contingency, the group prepared to reach the Well of Wisdom, with Ophelia using her Mystic Eyes to bypass its defenses.
Bai Mo and his allies survived the trial for Odin’s eye, prepared for Surtr’s awakening, and fought to prevent the Lostbelt’s destruction. After Surtr fell, Nidhogg emerged as the greater threat, while Ophelia chose to confront Surtr on her own terms.
Bai Mo and his allies defeated Nidhogg and Surtr, saved Ophelia, and helped Ortlinde adapt to her new dragon powers. After Northern Europe began recovering, Bai Mo entered Salem to find Ritsuka and became entangled in the witch hunt surrounding Abigail and Tituba.
