Overview of the Rose Investigation Arc
The Rose Investigation Arc is the second major story arc of Tokyo Ghoul:re, spanning chapters 31 through 72 of Sui Ishida's sequel manga. This arc focuses on the Quinx Squad's investigation into the Tsukiyama family's underground ghoul activities, a case that will lead them into a web of conspiracy, tragedy, and revelation. The arc is named after the "Rose" keyword used by the Tsukiyama family to identify their illicit ghoul auctions.
For Haise Sasaki — the amnesiac Kaneki — this arc represents a collision between his new life as a CCG investigator and the lingering traces of his past as a ghoul. The investigation forces him to confront Tsukiyama, a ghoul from his former life who recognizes him and attempts to reawaken his memories. This tension between Haise and Kaneki, between the CCG and his ghoul nature, forms the emotional core of the arc.
The Rose Investigation Arc is also notable for its exploration of the Quinx Squad as individuals. Each member of the squad faces personal challenges and growth during the investigation, from Shirazu's struggle with his sister's medical condition to Urie's ambition and Mutsuki's psychological instability. The arc uses the investigation framework to develop these characters, making their eventual trials more emotionally impactful.
The Tsukiyama Family and the Rose Garden
The Tsukiyama family is one of the oldest and wealthiest ghoul families in Tokyo Ghoul. Led by the patriarch Mirumo Tsukiyama, the family controls a vast network of legitimate businesses that serve as fronts for their ghoul-related activities. Their estate, known as the Rose Garden, is a luxurious compound that hides a dark underground — a secret auction house where captured ghouls are sold to the highest bidder.
Shuu Tsukiyama, the heir to the family fortune, is a character torn between his refined aesthetic sensibilities and his predatory nature as a ghoul. His obsession with Kaneki's unique flavor as a one-eyed ghoul drove much of his early behavior, but in :re, he has evolved into a more complex figure. He genuinely cares for Kaneki (now Haise) and struggles between his desire to restore Kaneki's memories and his understanding that doing so would destroy Haise's current identity.
The ghoul auctions organized by the Tsukiyama family reveal the dark underbelly of ghoul society. These events are attended by wealthy ghouls from across Japan who bid on captured ghouls — often for consumption, sometimes for other purposes. The auctions are protected by hired ghoul security and have never been successfully raided by the CCG, making them a symbol of the inability of human institutions to control ghoul criminal enterprises.
Investigation and Undercover Operations
The Quinx Squad's investigation of the Tsukiyama family begins with standard intelligence-gathering but quickly escalates into a complex undercover operation. Haise Sasaki, using his strategic brilliance, devises a plan to infiltrate the ghoul auction by posing as a wealthy ghoul buyer. This undercover mission requires the Quinx members to suppress their human identities and fully adopt ghoul personas, testing their training and psychological resilience.
The investigation reveals the extent of the Tsukiyama family's influence, which extends far beyond the underground auction. They have connections to the Aogiri Tree organization, the Clown group, and even elements within the CCG itself. The Quinx Squad finds themselves navigating a complex web of alliances and betrayals, unsure who can be trusted and what the true agenda of the investigation is.
Haise's leadership during this investigation demonstrates his growth as an investigator and strategist. He shows tactical brilliance in planning the infiltration, emotional intelligence in managing his team, and increasing confidence in his abilities as a CCG investigator. Yet every success brings him closer to the truth of his past, and the arc builds inexorably toward the collision between Haise Sasaki and Ken Kaneki.
The Auction Raid and the Clown Involvement
The auction raid is the centerpiece action sequence of the Rose Investigation Arc. The CCG deploys significant forces to assault the Tsukiyama family's underground auction, expecting a straightforward raid. However, they walk into a trap orchestrated by the Clown organization — a mysterious group of ghouls who have been manipulating events from the shadows throughout the entire series.
The Clown organization, led by the enigmatic Uta, reveals itself as a major antagonistic force during the auction raid. Unlike the Aogiri Tree's revolutionary goals or the CCG's institutional power, the Clowns operate purely for their own amusement. They play both sides against each other, revealing just enough information to keep the conflict going without ever fully committing to either faction. Their involvement in the auction raid transforms what should have been a straightforward CCG victory into a bloody stalemate.
The battle during the auction raid is chaotic and brutal. Both the Quinx Squad and veteran CCG investigators are pushed to their limits by the Clown members, each of whom possesses unique and deadly Kagune abilities. The fighting showcases the Quinx Squad's growth as a team, with each member contributing their specialized skills to the battle.

Shirazu's Sacrifice
Shirazu Gin's death is the emotional climax of the Rose Investigation Arc. As a member of the Quinx Squad, Shirazu was the team's heart — brash, loud, and endlessly optimistic. His primary motivation for joining the Quinx program was to earn enough money to pay for his sister's medical treatment. Throughout the arc, Shirazu struggles with the increasing danger of his missions, torn between his duty to his squad and his responsibility to his family.
During the auction raid, Shirazu sacrifices himself to protect his teammates from a devastating attack. His final moments are heroic but tragic — he dies knowing that his sister will be left without him, that his dreams of a normal life will never be realized. His death serves as a brutal reminder of the cost of the ghoul conflict and the price that investigators pay for their service to the CCG.
The impact of Shirazu's death on the Quinx Squad is profound and lasting. Haise, in particular, is devastated, seeing in Shirazu's fate a reflection of his own inability to protect those he cares about. The death forces the remaining Quinx members — Urie, Mutsuki, and Saiko — to confront their own mortality and reconsider their reasons for fighting.

Character Development and Thematic Depth
The Rose Investigation Arc is notable for its deep character development, particularly for Haise Sasaki. Throughout the arc, Haise experiences increasing flashes of his past as Kaneki — recognizing Tsukiyama, feeling echoes of his former relationships, and struggling with the identity that lies beneath his CCG training. This internal conflict reaches its peak when Tsukiyama directly confronts him, forcing Haise to acknowledge that there is more to his past than he has been willing to accept.
The arc also explores the theme of family, both biological and chosen. The Tsukiyama family represents biological family in all its complexity — love, obligation, secrets, and sacrifice. The Quinx Squad represents chosen family, a group of people bound together not by blood but by shared experience and mutual care. The contrast between these two forms of family runs throughout the arc, asking which is more meaningful and which demands greater loyalty.
Memory and identity are central thematic concerns. Haise's journey through this arc raises profound questions about the nature of identity: if all your memories are erased and replaced with new ones, are you still the same person? The arc suggests that identity is not a fixed state but an ongoing negotiation between past and present, between who we were and who we choose to become. This theme resonates throughout Tokyo Ghoul:re and reaches its fullest expression in the arc's later chapters.
Strategic Analysis: Pacing and Structure
From a narrative design perspective, the Rose Investigation Arc represents a shift in pacing from the introductory arcs of :re. Where earlier chapters focused on establishing the Quinx Squad and the new CCG dynamics, this arc accelerates the plot while deepening character work. The investigation structure provides a natural framework for introducing the Tsukiyama family's world, with each clue leading deeper into the conspiracy.
Ishida's art in this arc reaches new levels of sophistication. The contrast between the elegant, refined world of the Tsukiyama estate and the brutal violence of the ghoul auctions creates a visual tension that mirrors the thematic conflict between civilization and savagery. The Rose Garden itself becomes a symbol of beauty masking horror — the delicate roses fertilized by the blood of slaughtered ghouls.
The arc's structure follows a classic three-act format within the larger narrative. The first act establishes the investigation and introduces the Tsukiyama family's world. The second act covers the undercover operation and the infiltration of the auction. The third act delivers the raid, the Clown betrayal, Shirazu's death, and the aftermath. This clean structure makes the Rose Investigation Arc one of the most tightly plotted arcs in Tokyo Ghoul:re, a self-contained story that also advances the series' larger narrative.
