Princess Tashen is the central character of the animated short Roots, which forms part of the larger Taisu anthology project. She is portrayed as a lonely princess who lives in isolation within a world where a magical energy called Taisu is said to connect all things. Her circumstances leave her emotionally withdrawn, and her life is defined by solitude before the events of the story begin.

Her role in the story is set in motion by chance when she discovers a pair of twin flowers. These flowers grant her the ability to communicate across realms, allowing her to establish a connection with Aila, a foreign girl living in a completely different world. This meeting becomes the emotional core of the narrative. Through their conversations, Tashen gradually opens up her heart, moving from a state of isolation toward warmth and openness. The relationship with Aila is therefore her most significant bond and the main catalyst for her development, transforming her quiet loneliness into a growing sense of connection with another person.

The twin flowers serve as her notable ability within the story, functioning as a magical means to bridge vast distances and speak with someone outside her own realm. While her motivation is not explicitly detailed, her behavior suggests a deep longing for companionship that the flowers unexpectedly fulfill. The story also carries an underlying sense of tension, as the shadow of war looms over the two girls, threatening the fragile bond they have formed. Further specifics about her background, personal history, and abilities beyond the flower connection remain limited, as the short offers only a brief glimpse into her world.
