Description
Tomomori Taira, fourth son of Taira clan leader Kiyomori and Nii no Ama, has a younger brother Shigehira and younger relatives including Koremori, Atsumori, Tsunemasa, and Tadanori. Born in 1152, he died during the naval battle at Dan-no-ura on April 25, 1185. As Commander-in-Chief of the Taira army, his martial prowess established him among the clan's most skilled warriors, making him a dangerous battlefield rival.

In the narrative, Tomomori antagonizes as a key Heike military leader opposing the Genji clan. He fights in pivotal victories like Uji in 1180 alongside Shigehira and Mizushima in 1183. His strategies intertwine with the Taira goal of unleashing vengeful spirits to disrupt the world's energy flow—a conflict directly challenging protagonist Nozomi, the Priestess of the White Dragon tasked with sealing these spirits.

Tomomori orchestrates a critical ambush against Nozomi and her allies in the capital, causing her comrades' deaths and forcing the White Dragon God Hakuryu to sacrifice his life essence to send Nozomi back to her original timeline. This event ignites Nozomi's resolve to alter fate using the White Dragon's power.

In the game expansion *Izayoiki*, Tomomori gains narrative depth through the "Mixjoy" feature, which integrates original game save data to unlock his dedicated romance route. Completing this route carries his presence and special events into the sequel *Unmei no Labyrinth*, where he appears with updated character portraits and attire.

In the anime *Owari Naki Unmei*, Tomomori persists as an adversary in the war-torn setting. His actions intensify the central conflict where Nozomi must choose between protecting Genji allies like Minamoto no Kurou Yoshitsune or her childhood friend Masaomi, who leads the Heike forces.

Tomomori favors combat and pragmatic warfare, expressing concern over rigid traditions while valuing tactical flexibility. He notably acknowledges Nozomi's swordsmanship skills and determination despite their opposing allegiances. His modern legacy includes prominence as a kabuki play subject, reflecting enduring cultural impact.
