It's been a week since Arthea started distancing herself from Cavio, lately, for some reason, she has become quieter not only that for these few days her sleeping hours increasing day by day she almost doesn't have time to take care of Demian anymore she must ask Merry the cook to taking care of Demian. Cavio knew his sister was hiding a big secret from him but every time he tried to ask Arthea became defensive therefore he can only give in at the same time, Cavio's worries grew bigger and bigger by the day.
Actually, his worry for his sister had existed since Arthea asked for the power to predict the future, Cavio knew she was asking for that power to protect him because why should you fight if you can avoid it.
However, Cavio realized that this power was not given for free he knew there was a price he had to pay though he didn't know what it would be.
