Concerned for her safety, teammates Ruido Resonance in Astraea and Marlene Vlady in Abulhool attempt to catch up to the runaway fighter, but the drive malfunctions and fires a concentrated blast of GN Particles within the surrounding area. Ruido and Marlene are unable to handle the concentrated blast of particles and are killed, while Chall's face is scarred and her hair is turned prematurely white.

File No.14 - Sefer Rasiel
Chall visited Moreno's medical office for her regular treatments. Chall, whose body has been bathed in an overdose of GN particles in the "Plutone Accident", had a heavy disability on her cells. Her telomeres are damaged, and regenerative treatment also can't be done. As it is said that cell division can't be done normally, without the ability to do renewal, she also can't live normally. 874 offered the nanomachines that repair the cell disorder. When the restoration of the telomeres is done, perpetual youth is achieved too. Moreno continued to study GN particle toxicology along with Chall's medical treatment.
