The revelation that Lady Oichi serves as "The Mourner," a high-ranking member of the Shin Bakufu in Assassin’s Creed Shadows, stands as one of the most complex narrative shifts in the late-game campaign. As the sister of Oda Nobunaga and a character initially presented as a sympathetic ally to Yasuke, her unmasking during the quest "The Wheel Unmasked" forces players into a high-stakes moral dilemma. This decision not only impacts the immediate emotional dynamic between the dual protagonists, Yasuke and Naoe, but also dictates whether one of the game's most intricate romance subplots remains accessible.

Understanding the Identity of The Mourner

Long before the final confrontation on the northern shores of Lake Biwa, the game drops subtle environmental and musical cues regarding Lady Oichi's dual life. Her tragic history—marked by the loss of her husband Nagamasa Azai and the volatile political climate surrounding her brother—provides the foundation for her involvement with the Shin Bakufu. Known within the shadows as "The Wheel," she wears the mask of the Mourner, a symbol of her grief and the desperate measures she took to protect the people of Omi during years of famine.

Players track her down after a lengthy investigation involving the collection of intel in the Omi region. The trail eventually leads to a secluded estate on an island in northern Lake Biwa. The mission design here emphasizes stealth, requiring players to navigate underwater tunnels and dense thickets to reach the inner sanctum of the Shin Bakufu's local operations. It is within a quiet, candle-lit building near a viewpoint pagoda that the truth is finally laid bare.

The Pivotal Choice: Sparing vs. Attacking

Once the mask is removed and Lady Oichi’s identity is confirmed, a tense cutscene unfolds involving both Yasuke and Naoe. The game presents a binary choice that serves as a defining moment for the relationship between the two protagonists.

Option 1: Sparing Lady Oichi (As Yasuke)

Selecting this option aligns with Yasuke’s sense of bushido and his personal history with Oichi. Yasuke argues that building a new world requires mercy rather than a perpetual cycle of blood.

  • Narrative Outcome: Naoe is visibly frustrated, feeling that her father’s death and the suffering caused by the Shin Bakufu demand immediate justice. However, she begrudgingly yields to Yasuke’s judgment. Naoe expresses her anger by throwing a shuriken into the wall before exiting.
  • Consequences: This path is the strictly required choice for those wishing to pursue the full romance arc with Lady Oichi. She survives without injury and expresses deep remorse, resolving to work against the very organization she helped lead.

Option 2: Attacking Lady Oichi (As Naoe)

Choosing to attack reflects Naoe’s burning desire for vengeance against those who dismantled her clan and killed her father.

  • Narrative Outcome: As Naoe lunges with her blade, Oichi’s loyal attendant, Kuma, intervenes. He takes the hit intended for his mistress. Naoe is momentarily shocked by the unintended collateral damage but remains defiant, asserting that the poor always pay for the crimes of the powerful.
  • Consequences: Surprisingly, Lady Oichi survives this encounter as well. Yasuke steps in to de-escalate the situation. While the immediate atmosphere is more hostile, Oichi eventually reconciles with Yasuke the following morning, confirming that Kuma will survive his wounds. Interestingly, even this choice allows for the romance line to continue, though the emotional transition feels significantly more strained.

Rewards and Legendary Gear

Regardless of the choice made during the confrontation, the gameplay rewards remain consistent, ensuring that players are not mechanically punished for their narrative preferences. The most significant reward is the Myth Slayer, a legendary katana that belonged to Oda Nobunaga himself.

This weapon is a top-tier endgame option for Yasuke, featuring high base damage and a unique "Improved Riposte" engraving. This engraving significantly increases the damage window and lethality of counter-attacks, making it an essential tool for players who favor a parry-heavy combat style. In addition to the sword, players receive 300 Mon and a substantial amount of experience points, alongside the unlocking of the "Cloud Gazing" and "The Wheel Turns" quests.

The Yasuke and Lady Oichi Romance Arc

The relationship between the African samurai and the noblewoman is a slow-burn narrative that spans several regions and flashback sequences. To reach the "climax" of this relationship, players must follow a specific series of interactions and dialogue choices marked with the heart icon.

Step 1: The Foundation in "An Education"

The romance technically begins early in Yasuke’s personal questline, "An Education." This flashback sequence depicts Yasuke’s early training days under Sensei Nobutsuna. When introduced to Lady Oichi during this segment, choosing the reply "Some company might be nice" establishes the initial rapport.

Step 2: The Pilgrimage in "A Prayer for Omi"

Later, in the quest "A Prayer for Omi," players travel to the Shirahage Shrine on the coast of Lake Biwa. After performing rituals and making donations to the local NPCs, a quiet moment occurs at the pier. When Oichi speaks of the fleeting nature of life, the required romance response is: "I would spend my last night with you."

Step 3: The Meeting at Azuchi Marketplace

Following the events of "The Wheel Unmasked," if Oichi was spared, Yasuke will find a letter at the hideout from Lady Gamo. This directs him to the marketplace southwest of Azuchi Castle. Using the focus view (aim button) reveals blue search circles; Oichi is hiding in plain sight among the commoners.

  • Critical Dialogue: When she questions the future of their relationship, you must select "I miss your smile." Selecting "It is time to say goodbye" will permanently terminate the romance arc.

The Final Encounter on Cat Island (Okishima)

The quest "The Wheel Turns" concludes on Okishima, a large island in the center of Lake Biwa famously known for its feline inhabitants. This segment provides a rare moment of levity and peace within the otherwise grim campaign.

Walking with Oichi

Upon arriving at Okishima, Yasuke meets Oichi at the temple. As they walk together through the island's scenic paths, Oichi reflects on her life and her daughters. When the dialogue prompt appears, players should choose "I’m drawn to you."

The Daughters and the Dog (Fuji-maru)

Players are then tasked with finding Oichi’s three daughters scattered across the island. This part of the quest involves light exploration and conversation. During this sequence, the children discover an Akita dog named Fuji-maru, who previously belonged to the Akechi clan.

  • The Pet Decision: Players face a choice: keep Fuji-maru for the hideout or let him stay with the girls. While the heart icon is associated with letting the girls keep the dog ("You may have him"), it is important to note that keeping the dog does not actually void the romance. However, letting him stay is framed as the more "romantic" and selfless act in the context of the scene.

The Final Night

The arc culminates in a final conversation at the edge of the island as the sun sets. To initiate the final scene, players must select: "Let’s enjoy the moment." This leads to a fade-to-black sequence, implying an intimate night spent together before the harsh realities of the Sengoku period force their paths apart once more. The following morning, Yasuke wakes up alone, signifying the end of this specific chapter in his journey.

Strategic Value of the Oichi Subplot

Beyond the emotional weight, completing the Oichi/Wheel storyline is vital for players aiming for 100% completion and optimal character builds. The quest "The Wheel Turns" provides a massive 1000 EXP boost, which is crucial for reaching the level cap needed for the final series of assassinations. Furthermore, the information gained from Oichi leads directly to the discovery of the final corrupt Daikan, known as "The Hoarder," located in Kyoto.

This storyline also deepens the internal conflict within the Assassin Brotherhood. Naoe’s growth from a vengeance-driven shinobi to a more measured assassin is often highlighted in the "Cloud Gazing" quest that unlocks alongside the Oichi resolution. By sitting on the shores of Lake Biwa and discussing their choices, Yasuke and Naoe find common ground, bridging the gap between their disparate cultures and ideologies.

Navigating the Shin Bakufu Targets

Lady Oichi’s role as "The Wheel" is central to dismantling the Shin Bakufu’s influence in Central Japan. By navigating her questline, players essentially remove one of the most strategically gifted members of the enemy organization. Even if spared, her removal from the board as an active combatant and her transition into a repentant ally weakens the remaining targets.

When preparing for the "The Wheel Unmasked" mission, players should ensure they are at least Level 35-38. The island infiltration requires high-level stealth skills if playing as Naoe, or heavy armor and resilience if attempting the direct approach as Yasuke. The enemies on the island are elite guards, often equipped with fire-tipped arrows and heavy polearms, making the initial "cenote" entrance strategy the most viable for a clean run.

Final Thoughts on the Choice

In the grand scheme of Assassin's Creed Shadows, the choice between attacking or sparing Lady Oichi is one of the game's more "illusionary" binaries—meaning the core mechanical rewards and target reveals remain the same regardless. However, for players invested in the role-playing aspect of the game, the difference is night and day. Sparing her offers a more complete, emotionally resonant experience for Yasuke, allowing him to find a brief moment of human connection amidst a world of constant betrayal. It transforms Lady Oichi from a mere target on a list into a fully realized character whose choices echo the overarching themes of loyalty, grief, and the search for peace in a time of total war.
