Tobii is the last known KS marked as KS-5. The OAVI that Tobii has installed in his skull allows him to "cut spacetime". In other words he is capable of selecting an area in any time and space, and trading it with a different time and space. This is represented by a box cutting out the area he wishes to move to a different spacetime, a flash, and then the switch happens. These powers are managed and controlled by the Central OAVI. Gix Busok believes that Tobii is responsible for killing Jaya Utomo in the beginning of the story until Gix and Tobii accidentally cross paths while they are both scavenging for food. Tobii helps Erika Utomo kill Jamal after his fight with Bambang which results in what appears to be Bambang's death. Tobii after meeting with Gix ends up traveling far enough back in time to a point before Tobii is authorized to use his OAVI so they are stuck in the past. The time they travel to is 4 days before the explosion of Mount Lawu aka October 9th, 2003. Gix helps Tobii get reauthorized to travel back to the present day and in the process steals the Really Secret Documents that contains the recipe for Tempe. During this journey through the past with Gix, Tobii forms a friendship with Gix and grows to care for him as a friend. The reason Tobii freed the KS in the first place is because he would be sent to an indeterminate time forever using another spacecutting OAVI as Jaya Utomo and Jojo Garong didn't want someone as powerful as Tobii running around with his powers. The reason they don't just destroy the Central OAVI to prevent Tobii's powers is because they still wish to use it with the stronger spacecutting OAVI for Project Switchstar.
