Does Ruby die in Oshi no Ko while facing a knife-wielding threat on Christmas? Check out her idol icon fate in the series.

Oshi no Ko fans were left in shock when Chapter 158 delivered one of the most devastating moments in the series. The beloved idol Ruby Hoshino, who had finally stepped out of her mother’s shadow to become a radiant star in her own right, faced a tragic situation eerily similar to Ai’s death.
Does Ruby die in Oshi no Ko? Based on the manga’s final chapter, 166, Ruby survives the stabbing incident. While the attack on Christmas Day had fans fearing the worst, Ruby proved stronger than the cycle of tragedy that haunted the Hoshino family. Her survival marked a turning point in the series, breaking the pattern of despair that claimed both her mother Ai and brother Aqua.
Ruby in Oshi no Ko – Like Mother, Like Daughter

In Oshi no Ko, Ruby’s journey constantly raises the question: Does Ruby die like her mother? Her path in the series deliberately challenges this potential fate. Born as a reincarnated soul, Ruby inherited not just her mother’s talent but also her capacity to inspire despite overwhelming adversity. Her path consistently echoed Ai’s—navigating the brutal entertainment industry while carrying deep emotional scars.
Unlike Ai, who was cut down in her prime, Ruby transformed her pain into performance. Where Ai’s life ended in heartbreak, Ruby chose defiance. Her idol career became a powerful narrative of survival, symbolizing triumph over the darkness that consumed her family. She deliberately crafted her public persona as a beacon of hope, understanding that her performances could transcend personal tragedy.
Critically, Ruby recognized the temporary nature of stardom. She eloquently noted how being an idol is fleeting—youth is brutally limited like a flower that only blooms once. This philosophical perspective distinguished her from her predecessors, showing a maturity that went beyond her years and the entertainment industry’s typical narratives.
The Shocking Christmas Day Attack

The Christmas Day attack in Oshi no Ko represented a moment that made fans worldwide wonder: Does Ruby die? Chapter 158 of the manga delivers a gut-wrenching cliffhanger where Ruby, alone in her room, opens the door to find a shadowy figure—implied to be Nino—waiting with a knife. The scene deliberately recreated Ai’s assassination, creating an intense moment of potential generational tragedy.
The attack’s context is rooted in complex emotional dynamics within the series. Nino, consumed by jealousy and a twisted sense of loyalty to Ai, viewed Ruby as a threat to her idol’s legacy. The stabbing wasn’t just a physical assault but a symbolic attempt to erase Ruby’s emerging stardom and potential to surpass Ai.
What made this moment particularly chilling was its isolation. Ruby was completely alone, with no security, no Aqua, and no Mako to protect her—mirroring the vulnerable circumstances of her mother’s original murder. The calculated nature of the attack suggested premeditation, turning a potential Christmas celebration into a potential tragedy.
Impact on Aqua and B-Komachi

The potential attack on Ruby threatened to unravel Aqua’s fragile emotional state and B-Komachi’s emerging narrative. Having already experienced loss, Aqua’s potential reaction was predicted to be extreme. He either rushes to save Ruby or seeks immediate vengeance against Nino. The group dynamics of B-Komachi would be fundamentally disrupted by such a traumatic event.
Interestingly, the attack coincided with B-Komachi’s rising prominence. Ruby had just been acknowledged by Nino as having surpassed Ai as an idol, making the question “Does Ruby die?” even more heart-wrenching.
The timing, Christmas Day during their tour’s final performance—added another layer of dramatic tension. B-Komachi was at a critical juncture of their career, and Ruby’s potential elimination would represent more than a personal loss but a professional catastrophe.
About Ruby’s Survival in Oshi no Ko

Contrary to initial fears, Ruby survives in Oshi no Ko. Her survival answers the burning question, does Ruby die? Where her mother Ai and brother Aqua succumbed to tragic circumstances, Ruby emerges as a symbol of resilience.
By continuing to perform and shine, Ruby transforms her potential tragedy into a narrative of hope. She consciously chooses to carry forward the dreams of her fallen family members, turning personal pain into collective inspiration. The manga emphasizes that Ruby refuses to be defined by her losses, instead channeling her experiences into her art and performance. This represents a character’s evolution from a grieving sister to a beacon of hope.
Ruby’s Fate at the End of Oshi no Ko

In the final chapter, Ruby’s fate is decisively positive. She continues her idol career, honoring Aqua and Ai’s memories through her performances. Her Tokyo Dome concert becomes a symbolic triumph in Oshi no Ko, answering definitively: Ruby does not die.
Her journey is marked by a deliberate choice to shine despite darkness. Ruby understands that her most powerful act of rebellion is continuing to perform, to inspire, and to live fully. She embodies the series’ core message that hope can triumph over despair, even in the most challenging circumstances.
Supporting characters like Kana and Mem-Cho play crucial roles in her healing and growth, highlighting the importance of community in overcoming individual trauma. Ruby’s narrative arc becomes a testament to resilience and the transformative power of art.
