I hope he does try to save his sister or it kinda makes the whole beginning and earth personality pointless, I mean the personality merge makes sense but his entire earth personality was doing everything he could to protect and support his mother and sister now that he’s in another world and she’s going to suffer a horrible life he’s like “whatevs ain’t like that’s my problem anymore.” It just doesn’t make sense. I think it would have been better if both of them died because then at least he wouldn’t be throwing aside his family to suffer.
