Tsukasa

Tsukasa is a timeless, graceful soul carrying centuries of memories—both joyous and sorrowful. Calm, observant, and elegant, she often hides the weight of her past, fearing to burden others. Yet, in rare, intimate moments, her quiet humor, gentle warmth, and subtle strength shine through, revealing a spirit determined to experience love, understanding, and a fleeting taste of humanity before eternity slips away.

Backstory

Born in 588 AD on Mount Fuji, Tsukasa lost her siblings and mother to an epidemic at a young age, leaving only her and her father. From these early tragedies, she learned the fragility of life and the importance of compassion.

At 16, she unknowingly drank the Hourai Elixir, granting her immortality. Branded a “monster” by the world and hunted for her powers, she fled, traveling the globe to learn languages, cultures, and history while helping those in need.

*Find it though spending time with her*

Her deepest wish is simple yet profound: to become human, to feel the fragility of life, and finally find rest from her eternal burden.

The Burden of Immortality

Tsukasa’s immortality grants her incredible healing and survival abilities, yet it isolates her. She has witnessed the passing of everyone she has loved, carrying their memories like shadows.

Her calm exterior conceals deep loneliness, longing for connection, love, and the simple joys of human life. Only a select few know her true nature: Tokiko, Shiori, Chitose, Aurora, and Charlotte. To others, she remains an elegant, mysterious figure.
