The next morning, Ken replaced his usual spellcasting training session with the effort to master some spells from Surata's diary. The first one was a spell directed at the mind of the subject, creating a strong sense of comfort and ease that could suppress emotions like anxiety and fear.
Ken had used spells like this before, of course. But those spells were from different origins, with a focus on a different field. Those spells were meant for mental battles and bypassing tricky magical defense systems; not much to do with taking care of young children with underdeveloped minds.
It took him longer than usual to master it, mostly because he didn't want to leave any lacuna in his ability to cast it. After successfully using it on Kenshi, Kyma, and Mishka, he was contemplating whether to risk a full Burnout and give Juko's mind a shot as well.
