Pinky, granddaughter of Silva the Great Soldier of Sekandas and daughter of Silva's deceased daughter Green, contracted the same fatal disease that killed her mother and grandfather during infancy. This disease originated from a curse in the Needle Tower. Spaak cured her using the "Prayer of Heaven" technique, transferring the disease to her grandmother Silva. This early experience instilled deep admiration for Spaak in Pinky and motivated her desire to prove she was no longer the fragile child he saved.

As the Great Child of Sekandas, Pinky wields several abilities. Silva taught her primary power, teleportation, allowing her to move herself and others to safety, though it drains significant energy. She also employs "Miraculous Pump," a destructive bomb-like attack utilizing her spirit companion Bambi, and possesses hand-to-hand combat skills from training. However, her combat proficiency remains notably less advanced than Silva's, evidenced by her failure in a G.C. test against her grandmother.

Joining Bucky and Kai on their journey to the Needle Tower, Pinky starts skeptical of Bucky's capabilities as Spaak's successor but later acknowledges his strength despite his abrasive personality. Her motivations include finding Spaak to demonstrate her growth and confronting the source of her family's curse at the Needle Tower. Pinky's relationship with Silva evolves from resentment over perceived rivalry—especially Silva's youthful transformation during their confrontation causing envy—to profound protectiveness after learning Silva absorbed her disease to save her. This fuels Pinky's vengefulness toward Hail, creator of the curse responsible for her family's suffering.

In critical moments, Pinky risks herself to protect others, teleporting Silva, Bucky, and allies to safety during Hail's attack and collapsing from exhaustion. Silva then instructs her to help protect the Twelve Worlds from Trouble Monsters, leading Pinky to remain with Bucky's group. During the final conflict, she aids in battling Slash-created illusions of Silva and Funen.

Regarding the Princess, Spaak's sister and a pivotal figure in the Needle Tower: She and Spaak survived their planet's destruction by Slash prior to the series. Paralyzed during an attack on their spaceship (the Needle Tower), she was placed in cryogenic sleep. Years later, Slash's "Poison of Awakening" disturbs her stasis, and she awakens fully possessed by him, exhibiting purple-glowing eyes and miasma-based powers.

While possessed, the Princess displays destructive tendencies and swordsmanship comparable to Spaak's. She wields her sword to generate lightning shocks and purple miasma that freezes inhabitants of the Twelve Worlds, including Bucky in childhood. After breaking free from her capsule, she battles Spaak and Bucky, breaking Bucky's weapon and overpowering him until Spaak uses "Prayer of Heaven" to purge Slash's influence. Freed, she loses consciousness and is caught by Bucky.

Following liberation, the Princess assists against Slash, using her spiritual abilities to enhance Bucky's powers for his "Pump Great Jibak" technique. After Slash's temporary defeat, she departs the Twelve Worlds with Spaak in their spaceship, leaving her sword for Bucky to wield in the final battle against Slash's dragon form.
