@criver I was about to comment that. please dont be a dumb dense main character for once . I hope he becomes the mediator between the demons and his anti-demon group to make both parties understand eachother . like im pretty sure that will happen but when? if the author want to milk this he'll make us wait for 20 chapters (mc escapes without listening to the demons reasons,he'll tell the anti demon corp the demons plan,they'll come up with a counter attack ,the demons will lose,his sister will be locked up in their research facility ,and he'll see how bad they are treated ,then he'll help her escape ,she is weak now ,they'll go to his anti demon group,and JUST THEN he will actually listen to her and they'll become part of the rebellion or something ...).
OOOR,he can waste 5 minutes of his time to just listen to her reasons next chapter and become the mediator
