Thank you Ryuo end everyone envolved for delivering such an awesome vn to us! I cannot imagine the ammount of time and effort you've put into this but it turned out great in the end.
!!!!SPOILERS!!!!
when glitch was tormenting Alex and every one was with him alex said he has to stop the Assention, that when Kaius reacted by "what did he just say!" so i think this isn't the first time kaius hear this and i think he heard it from Alerra. So my theory is When a demon try to Assend through a bibed (which they aren't supposed to do) that bibed become an informed and they lose Thier mind because of it, and in Alerra's case the demon was the closest to Assention and Aleera was fighting him but it was a battle neither one can win (because demons can't Assend through a bibed and a bibed cannot win mentally against a demon even Alex couldn't do alone) so they remain stuck like that, so Aleera wasn't just rambling she was fighting the tormenting she has to endure for 3 nights until she is put down, kaius believe in her but she couldn't win, so when Alex said the same thing as Aleera, kaius knew he was fighting and believed in him so that he guarded the outside of loken's home and he saved Alex from going to the blackzones and so unknowingly saved everyone.
In the end this is just a theory and my thoughts in the heat of the moment.
Be kind to each other.
Peace✌️
