And that is why, long after Rent-A-Girlfriend ends, fans will still be arguing about the girl with the slow heart and the explosive personality. She isn't the heroine of the story. But for many, she is the hero of their own. Do you think Ruka Kanae deserves a happy ending? Share your thoughts in the comments below, and check out our character rankings for the rest of the Rent-A-Girlfriend cast.
If Sumi represents the "safe harbor" of pure, uncomplicated support, Ruka represents the "storm." Sumi encourages Kazuya quietly; Ruka challenges him loudly. Why Ruka Kanae Divides the Fanbase No search for "Ruka Kanae" is complete without addressing the controversy. She is, arguably, the most hated and loved character in Rent-A-Girlfriend simultaneously. The Case Against Ruka Critics point to her immaturity. She kisses Kazuya without consent numerous times. She inserts herself into family gatherings and dates under false pretenses. She actively tries to sabotage Kazuya’s relationship with Chizuru not by exposing lies, but by brute-forcing her presence. To detractors, Ruka represents toxic persistence—the idea that "no" is just a hurdle to overcome. The Case For Ruka Defenders argue that Ruka is a tragic figure. Unlike the other characters who have social safety nets, Ruka is literally fighting against her own biology. Her bradycardia means that a future without Kazuya is a future of emotional numbness. Furthermore, she is the only character who holds Kazuya accountable. While Kazuya lies to his grandmother and leads Chizuru on, Ruka calls him out. She tells him he is a coward for not choosing.

It was because he was genuine, awkward, and desperate. He treated her like a real person during the practice run, not a hired commodity. And that is why, long after Rent-A-Girlfriend ends,
The argument for a theoretical Ruka win is thematic. Rent-A-Girlfriend is about the difference between rental (fake) and real love. Ruka’s love is the realest thing in the series. It is ugly, inconvenient, and persistent. In many other rom-coms, the girl who fights the hardest wins. In reality, and in this particular manga, the hardest fighter isn’t the right match. If you initially dismissed Ruka as "annoying," search beyond the surface. She is the only character in the main cast without a safety net. Chizuru has acting and her grandma; Sumi has her journey of self-improvement; Mami has her wealth and cynicism as armor. Ruka has only Kazuya. Her entire identity of "the energetic girlfriend" collapses if he leaves. Do you think Ruka Kanae deserves a happy ending
