The Ursus Student Self-Governing/Government Group[note 1] (U.S.S.G.) is a Terran organization. It is a band of five Ursus students who survived the uprising in Chernobog and its devastation. Currently, the U.S.S.G. is working together with Rhodes Island as its Operators in exchange for treatments for their psychological/physical illnesses.


Originally, the students of Chernobog were gathered up together at the Peterheim Middle School under the instruction of the Reunion leader Patriot in order to protect them from violence. Most of them were commoners but some were sons and daughters of local aristocrats from other upper-class schools. Tensions had already built up as both factions despised each other for social issues. However, the matter became worse when Mephisto was ordered to be in charged of the students. With his psychopathic nature, he completely restricted the food ration so that he could enjoy the infighting while having his crazy experiments on them for his Herds.[1]

The final straw that broke the peace was a fire in their school's storehouse which was accidentally set by Sonya. The disaster completely destroyed the students' food supply, resulting in a bloody conflict between the commoners and the aristocrats.[2] In order to protect themselves and their surviving resources from looting, many students formed their own bands. While such plan indeed helped prolong chances of survival for the young students, it could not resolve the bloodsheds among them as well as their traumatic experiences.

Under the suggestion of Anna Morozova, the Ursus Student Self-Governing Group was formed as a unique student union which composed of both the aristrocrats and the commoners.[3] Even then, it could not repair the distrust between them, especially after Sonya was appointed as the leader which aroused a lot of opposition from the aristrocrat faction. Under the name of "maintaining order," Sonya literally killed the opposition party either by force or by ordering death sentences onto the "convicts," leading to its drastic decrease of its members. By the time Sonya rescued Natalya out of her conscience, there was only four of them left in the union.[2]

After the devastating Catastrophe that destroyed Chernobog, the U.S.S.G. was able to escape from the school and hid themselves in unaffected districts before they were rescued by Rhodes Island. Even though the students have since received medical treatments from R.I. and are able to move on through psychological counseling, their trauma continues to leave a mark within their hearts until present days.


  • Vika: A friend of Istina who wished to seek shelter from the aristrocrat faction after realizing that the U.S.S.G. could not fully protect them. However, she faced a lot of opposition from other members.[2] As a punishment for her disobedience, Zima pronounced death sentence onto her by having her jump from the school building, and Istina could not do much but to watch her die. Her name was later given to Istina's teddy bear as a remembrance.[3]

Of the U.S.S.G. members above:

  • Zima is the de facto leader of the U.S.S.G..
  • Istina is the founder of the U.S.S.G..
  • Rosa acts as the figurehead of U.S.S.G. during their stay in Rhodes Island.

Health issues

  • Gummy suffers from PTSD as a consequence of her murder onto other students for her own survival. She also has nyctophobia due to the bad experience back in her school.
  • Istina possesses moderate PTSD as a consequence of witnessing Vika's death by Zima.
  • Zima suffers from severe PTSD with constant nightmares about the incident.
  • Rosa authorized the aristrocrat students to commit several atrocities onto the commoners during the occupation. The guilt from these events causes her to suffer from self-loathing, depression and suicidal ideation.[4]
  • Leto is hinted to have Oripathy after seeking fight against the Reunion members. It is possible that Mephisto implanted Originium inside her and then erased her memory.[5]
