Monogatari Series: Second Season EP5 - Tsubasa Tiger, Part Five

In her letter to the cat spirit, Tsubasa reveals that just like her, Kako is another apparition sired by her repressed feelings, this time of jealousy and asks her to return both to her heart, as she is finally determined to shoulder all of her negative feelings no matter how it will change herself. As Kako is about to burn Hitagi's apartment, Tsubasa appears to confront it. Despite having no chance to defeat Kako, Tsubasa manages to stall it long enough to Koyomi to appear and defeat it with Heartspan. Before absorbing both the cat and tiger spirit, Tsubasa finally confesses her love for Koyomi, and as expected, he rejects her, assuming that his love for Hitagi is stronger. After her family finally rents another house for them to live, it is revealed that Tsubasa's hair developed white stripes just like a tiger, that she hides by dying them black, and she had at last asked her parents for a room just for herself, as a sign that she finally had become a true member of her own family.
