Rima and others shuddered when Aria suddenly gazed at them so intently.
Old man Raku looked deeply at Max. When Aria glanced at him, even though she concealed it immediately, he had noticed her surprise.
So, although he didn't know what exactly was going on, he knew her sudden interest in Rima and the others was because of something she noticed about Max.
'It seems my instincts were right. This kid sure is not someone ordinary.' He thought.
Previously, in the dark mages' lair, when he witnessed Max killing the leader of dark mages in a single blow, he was both happy and sad.
Happy because they had survived and sad because he could see that Max, who wasn't a three-star mage, had done some irreversible damage to himself to cast that overbearing fire spell to kill the leader.
