Description
Princess Surya hails from ancient India during the Gupta Empire era, approximately 1500 years ago. She was a royal figure whose kingdom faced invasion, resulting in the death of her protector (and implied husband). Divine intervention manifested as a luminous hand rescuing her from capture, preserved her in suspended animation within Himalayan ice for centuries.

Her frozen body was discovered in the Himalayas by archaeologist Dr. Takeshi Aikawa and his team. Modern technology proved insufficient for revival, necessitating an ancient ritual involving a sacred artifact called the "Sex Grail" or "sex cup." This ritual required mixing male and female bodily fluids within the cup, which were then administered to her, successfully restoring her life.

Upon awakening, she became hunted by antagonistic forces, primarily the Naga Tribe led by Prince Rudra (or Rudracin). Their goal was to exploit her connection to eternal life by forcibly marrying her and harnessing the grail's power. This pursuit fueled the central conflict across both manga and anime adaptations.

Her narrative significance extends beyond royalty. In the anime adaptation, she recognizes Ryu Aikawa (Dr. Aikawa's grandson) as the reincarnation of her ancient protector. This connection forms a core plot element, culminating in a climactic battle within Shambala—a mythical realm accessed via the grail. During this confrontation, she guided Ryu to reclaim memories of his past life, enabling him to defeat Rudra.

Her ultimate purpose differs between media. In the anime, divine entities reveal her destiny is to sleep until a future global catastrophe, after which she will awaken to save humanity. Following Rudra's defeat, she shares a consensual kiss with Ryu before ascending into space encased in a luminous vessel. The manga concludes differently: after engaging in sexual union with Ryu inside the "Sacred Egg" (a cosmic entity), the egg splits. One half returns Ryu to Earth, while the other transports her into space. Her essence, alongside Ryu's DNA, merges with the Sex Grail, which is resealed within its temple origin.

Her character embodies themes of destiny and divine mandate. Historical records do not verify her existence.
