Web Novel Differences

 * The events of this volume heavily deviate from the web novel version of the story, with the author describing it as the "good end" to the latter's "bad end".
 * The diverging point between the two versions was when Shun was forced to decide whether to let Shiraori destroy the System, killing half of humanity in the process, or sacrifice the gods instead: whereas he sides with humanity in the web novel, in the light novel he resolved to find a solution where no-one would have to die, with Ronandt, Hyuvan, Nia, and Reise siding with him.
 * Because Ronandt did not support them by using his teleportation magic to gather allies from all over the world, Dustin and the demons' forces are overwhelmed by Ariel's Taratects and defeated.
 * Because half of their members defected and Shun's party was not there to back them up, Güliedistodiez' remaining dragons are defeated by Wrath and Sophia.
 * Because Shun did not seek lock them out of the system, he did not fight Ariel and subsequently Shiraori.
 * The second half of the volume was all original content.
 * Ms. Oka learned through her Student Roster skill that D intended to shut down the System regardless of which side won, since sacrificing Shiraori, Güliedistodiez, and Sariel would still not have been enough to heal the planet.
 * Ariel's party joins forces with Shun's and lets them into the System core to try out the latter's alternate solution: teleporting to D's location and confronting her.
 * Ariel's and Shun's parties confronted D and learned both her and Shiraori's true identities as the real Wakaba Hiiro and the classroom spider respectively.
 * Since they entertained her until now, D offered to save the planet if Ariel's and Shun's parties managed to defeat her. However, despite D heavily handicaping herself, they are easily defeated. Fortunately, Shiraori arrives to save them and defeats D using the scythe she herself gave her.
 * Since their fight was meaningless now, Shiraori and Güliedistodiez agreed to a ceasefire.
 * After the battle, D wanted Shiraori to become her subordinate and she accepted due to believing she owed her for saving the planet.
