@I_am_nemo imagine if they believe them... They will most likely create a special unit and will experience this hell again. So we could theoretically see them again rescuing the girls or smth else.
@Shyri no because they don't "share" the skill. They just have the same since he copied it. So the ghost was also copied so that he can also have one (as it is the effect of the skill). So those identical skills count as different and for this reason can they not see each other. I forgot to...
@Macrendil I think so too but the question is if she also has a system and if yes which type? I don't think she would have the same system as his brother and if so that would be hilarious.
If my family would be like this I would cut all ties with them. I really admire his patience and self-control. I'm not sure if I could be calm in such a situation even though I'm a calm person.
