NANCY MAKUHARI SPOILER!
The partnership becomes the emotional center of the OVA because Nancy is hiding something much larger than another intelligence affiliation. She is herself an I-jin, created from Mata Hari, and Ikkyu has another Nancy working beside him. The existence of two physically identical Nancys turns the final confrontation into more than a simple double-agent reveal.
The Nancy who worked with Yomiko survives Ikkyu's attempt to kill her and defeats her counterpart. By switching the gun into the opposite hand, she convinces Ikkyu that the other Nancy survived, gets close enough to kill him, and stops his plan from within. Yomiko tries to escape the rocket with her afterward, but Nancy chooses to remain with the dying Ikkyu rather than leave him to die alone.
Her betrayal is real. So is everything she came to feel for Yomiko. The OVA lets both things remain true.
NANCY THROUGH THE ARCHIVE //
I-JIN CONSPIRACY & SYMPHONY //
Open page →The Partner Yomiko Trusts Becomes Part of the I-jin Trap
Inside the I-jin fortress, that trust is turned against Yomiko. Nancy appears to deliver her into Ikkyu's hands, and Yomiko is forced to confront the possibility that their entire partnership was manufactured.
Then the story reveals the missing piece: there are two Nancys.
Two Mata Hari I-jin · One Small Difference
The small physical tell is handedness. When the two Nancys finally fight, the survivor is able to exploit that difference by deliberately using the opposite hand and allowing Ikkyu to believe the wrong woman won.
That mistake gets her close enough to kill him and break Ikkyu's endgame from inside the rocket.
She Stops Ikkyu, Then Refuses to Leave Him Alone
Yomiko still tries to save her.
She prepares to escape the doomed rocket with Nancy, but Nancy stays behind with Ikkyu's body. Her final decision does not erase what he did or excuse her part in the conspiracy. It shows that killing him did not erase whatever she once felt for him either.
Historical Figures Recreated as Superhuman Operatives
Gennai Hiraga arrives with spectacular electrical weaponry. Jean-Henri Fabre commands insects. Otto Lilienthal takes to the sky. Genjo Sanzo is transformed through the imagery surrounding his legendary journey. Stephen Wilcox becomes part of the machinery supporting the I-jin fortress. Ludwig van Beethoven is revived because his music is the final weapon Ikkyu needs.
Nancy makes the idea more complicated. She is also an I-jin, derived from Mata Hari, but spends most of the story inside the British Library operation.
WHAT THE OVA DOES NOT EXPLAIN:
R.O.D gives enough information to understand that these people have been recreated and altered, but it does not provide a complete technical system for how every I-jin is made. The abilities are built around the historical figure, not around a detailed rulebook.
The Rocket · Beethoven · A Worldwide Performance
The rocket is not the weapon by itself. It is the delivery system for Beethoven.
That distinction matters because destroying the fortress does not automatically stop the plan. Once the rocket launches, Yomiko has to continue the pursuit aboard it and stop the performance directly.
The Relationship That Makes the Betrayal Hurt
Nancy is almost everything Yomiko is not. She is composed, physically confident and comfortable moving through danger. Yomiko is distracted, emotionally transparent and much more interested in books than looking like a professional secret agent. The contrast works immediately because neither woman is treated as the correction for the other.
Their partnership becomes personal quickly. Yomiko worries about Nancy when she is hurt, trusts her instincts in the field and begins treating her less like another British Library operative and more like someone she genuinely cares about.
That is why Nancy's apparent betrayal lands so hard. Yomiko does not respond by reducing Nancy to an enemy agent. Even after the evidence turns against her, Yomiko keeps trying to understand what happened and keeps trying to reach her.
By the final episode, the mission is no longer the only reason Yomiko is pursuing Nancy. Saving her has become a goal in its own right.
R.O.D OVA MASTER COMBAT LEDGER //
Open page →Episode 3 · I-jin Fortress · The Two Mata Hari Clones
One Nancy is left behind while the other reaches the rocket. Ikkyu assumes the woman who arrives is his partner.
He is wrong.
WHY IT MATTERS:
The fight does not end when one Nancy goes down. Its real payoff comes later, when handedness reveals that the survivor has been impersonating her counterpart long enough to get close to Ikkyu.
Yomiko & Nancy vs. Otto Lilienthal (Aerial Pursuit)
Open →Episode 1 · New York · Paper Takes Flight
They finally bring Otto down by attaching paper to his glider and sending him into the Statue of Liberty.
WHY IT MATTERS:
This is where Yomiko's ability stops looking like a single combat trick. Paper is not just something she can sharpen or hide behind. If the situation requires an airplane, she makes an airplane.
Episode 2 · India · Nancy Goes Down, Yomiko Stops Holding Back
Sanzo survives long enough for the stolen book to continue moving through the I-jin operation, but the fight itself is over.
WHY IT MATTERS:
This is one of the first times the OVA shows what happens when Yomiko's emotional attachment to another person becomes stronger than her usual distracted gentleness. Nancy being hurt changes the way Yomiko fights.
Episode 3 · The Rocket · Ikkyu's Plan Reaches the Sky
Yomiko reaches Beethoven before the performance can be completed and destroys the organ strings, stopping the Death Symphony itself.
With the plan broken, Yomiko prepares to escape the doomed rocket with Nancy. Nancy refuses to leave Ikkyu's body behind and remains aboard while Yomiko falls away to safety.
WHY IT MATTERS:
The OVA does not resolve its climax with one final boss fight. Three different choices stop the plan: Nancy deceives Ikkyu, Yomiko stops Beethoven's performance, and Nancy makes one last decision that Yomiko cannot make for her.

R.O.D never acts embarrassed by the premise. A stolen book can trigger the same response another spy story would reserve for a stolen weapon, and the agents pursuing it may include a woman who controls paper and another who walks through walls.
