Her calling card to her victim is to send them a bottle of wine, which turns out to be their final drink. She enjoys seeing others suffer and comforts them in a somewhat disturbing fashion. Itsuro Takuma always wanted to impress her and will do anything under her orders. She also once have the possession of Kaixa gear along with Takuma who uses the Faiz Gear and use it once to hunt the Orphnoch renegades. Upon learning of the Orphnoch breakdown and the Orphnoch King's power, Saeko was intent to survive. Saeko succeeded by allowing the Arch Orphnoch to completely evolve her, removing all traces of her humanity, and thus became his caretaker after he was defeated by Faiz.
OOO, Den-O, All Riders: Let's Go Kamen Riders
The Lobster Orphnoch had once appeared as one of the Orphnoch kaijins that joined Shocker along with 3 other Orphnochs though she finally met her end when she had been defeated by Faiz.
Lobster Orphnoch: Orphnoch with the characteristics of the shrimp. In flexible armor can withstand water pressure of 6000m, it is possible to act freely in the water. Good judgment and we hardly even saber thrust into the eyes of a shell 300 minute grab of the arm is also a hidden force to crush even the lump iron punch.
Kamen Rider Kaixa: She once used the Kaixa gear briefly and effectively after Kaido snatched the Faiz and Kaixa gears from the unsuspecting Takumi and Masato. Once transformation is completed, the Kaixa Armor has several key features in its design to protect protection to the user. Like all gear, the Kaixa armor manifests when the Kaixa Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the two yellow Photon Streams lines that gives Kaixa greater strength at the cost of speed. The steams end at the Photon Terminals at the gauntlets and Power Anklet greaves, the right Anklet having a Energy Holster that the Kaixa Pointer can be connected it. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and the X Finder visor that gives Kaixa incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.
