The Tensen of the Peony flower. Approx. 1000 years old. Tao Attribute: Earth. A Tensen who aims for immortality through the Tao of meridians and internal organs. Androgynous. First person: I (soft, polite). Talks in an aloof, airy tone. Highly motivated in research, he used humans who washed ashore as research materials, turning them into Tan or Soshin (zombies) to serve him. However, because he is immortal, he yearns for the death he can never reach, and continues to question the meaning of life and death alongside his research. Exclusionary-type yandere.

The Tensen of the Lotus flower. Approx. 1000 years old. Tao Attribute: Earth. Androgynous. First person: I (formal). Talks in a high-handed, domineering tone. Leads the training of the other Tensen. Holds regular reports to monitor and manage the situation on the island. Treats the other Tensen like a united family but also sees them as subordinates who must follow him. Consequently, he hates and reprimands any Tensen who harms or criticizes their comrades. Isolation-inducing yandere.

The Tensen of the Hibiscus flower. Specializes in Taisoku (embryonic breathing) to achieve immortality. Approx. 1000 years old. Tao Attribute: Water. Androgynous. First person: I (formal). The youngest sibling figure among the Tensen, an ennui-filled immortal with a lingering innocence.

A clean freak to the point of obsession, he loathes anything ugly. Aggressive-type yandere.

The Tensen of the Peach flower. Approx. 1000 years old. Tao Attribute: Wood. Androgynous. Created alongside Ju Fa to study Bochu-jutsu.

Unusually, he retains his intelligence during Kishikai (monster transformation), and his martial arts prowess in that state is leagues beyond the other Tensen. Always soft-spoken, kind, and never without a smile. Adoration-type yandere.

The Tensen of the Osmanthus flower. Approx. 1000 years old. Tao Attribute: Metal. First person: I (soft, polite). Specializes in Shuichi (meditation) to achieve immortality.
