Oshi No Ko Chapter 145 reveals a lot about the mysterious character Tsukuyomi. She entered the limelight with her first role in the movie 15 Years of Lies.
But what's even more important is that fans learn Tsukuyomi's true identity and her connection to Aqua and Ruby from her past lives as Sarina and Gorou.
In the previous chapter, readers witnessed the return of Tsukuyomi after Ruby praised Melt for his role as a doctor.
This implies that Tsukuyomi may be preparing for her acting debut. Chapter 145, titled Children, confirmed this as Tsukuyomi finally made her debut in the film 15 Years of Lies.
Notably, she was set to play the childhood versions of both Aqua and Ruby. Ruby isn't too excited about Tsukuyomi's younger role.
She felt that Tsukuyomi made her character seem less mature than she remembered. However, during a scene where Tsukuyomi and Ruby were playing young Ruby and Ai, something interesting happened.
Ruby picked up Tsukuyomi and suddenly she saw a vision of her past. This implies a connection between Tsukuyomi and the twins' past lives.
When Tsukuyomi took on the role of Aqua, everyone, including Kana, felt that her acting was too cute. They remember Aqua as mature and talented as a child.
But everything changes when Kana and Ruby begin to love Tsukuyomi because she reminds them so much of young Aqua. When Aqua joined them, the manga revealed Tsukuyomi's backstory and her connection to the twins.
What is the meaning of Tsukuyomi in the twins' past lives?
In Aqua and Ruby's previous lives, they were known as Gorou and Sarina. Interestingly, Tsukuyomi used to be a crow.
While Sarina was being treated at the hospital, she came across an injured crow. She seeks help from Dr. Gorou Amamiya, even though he has no veterinary training.
Gorou assisted in treating the bird and together they nursed it back to health. After the crow regained its strength, Gorou and Sarina released it back into the wild.
However, the crow kept returning to Sarina's bedside in the hospital. This continued until Sarina succumbed to her illness.
Later in the manga, the story returns to the present. Tsukuyomi is shown contemplating the twins, Aqua and Ruby, remembering how she may have portrayed them as too childish.
Throughout their lives, Tsukuyomi always considered them adorable children. This also implies that Tsukuyomi has been observing Aqua and Ruby since their birth, fully aware of their past identities.
Many fans have various theories about Tsukuyomi's identity and her connection to the twins. However, it turns out that her relationships with Ruby and Aqua are actually very heartwarming. She continued to treat them as children, appreciating their growth as she watched them.
