trapped in the entrapment field. Vital Guarder - Eysfina, the pod chain system used to generate an entrapping gravity field. Used as a means to detain their target in order to safely enter firing range. GREY Gespenst Conrad Vicuss's Vaia ship most akin to the Ryvius, also possessing a comparable and somewhat humanoid vital guarder, but fuzed to a large fixture system at its arms and legs. It is only upon seeing Neya and recognizing her form as that of his deceased daughter that he realizes what grave wrongs he has committed. The Gespenst is capable of forming blades from gravitational forces to cut through the targets that it closes in on. It also has the ability to merge with existing 'vaia squids' to amplify its mass and gravity control and power, much to Stein's dismay, as he cannot stand to see anything that defies scientific logic. Vital Guarder - Geist, a humanoid body fixed vital guarder with tremendous gravitational force power, estimated by Stein's numbers of being at least twice as powerful as the Ryvius. These observations were more or less proven when the Geist merged with a number of Vaia squids around it, significantly boosting its attack power. Geist continued to destroy parts of the Ryvius's vital guarder, until it separated from the large ball of mass it created around itself, and began a powerful supercharge of energy. In one final ramming attack, the Geist was annihilated, along with the Einvalt, while everyone in the lift ship is safe. After a maddeningly fierce battle, and the loss of his vital guarder, his final words after once again being face to face with Neya, were: "Attention all hands. The Ryvius is piloted by children, I want them rescued!" before killing himself with a gun, proof that he had understood the situation on board the Ryvius during most of his pursuit of it. (He had earlier stated that the student's pleas for rescue must be a trick). This marks the end of the war between the Orbital Security Bureau and the crew of the Ryvius. Themes and symbols Infinite Ryvius is a complex series with many underlying themes and symbolisms. Responsibility - The only adult characters aboard the Ryvius are written out of the story at an early stage and throughout the series the characters are regularly forced to take responsibility for difficult decisions in the absence of adult guidance.
