Afterward, Yuri told Reiger that although his disintegration magic had become a kind of control system magic, the control system property might not necessarily manifest in other forms of magic.
"Those magicians with an aptitude for control system magic usually have only one or two types of magic that exhibit control system characteristics, resulting in unusual changes; the rest of their magic remains quite normal," she explained.
Yuri also told Reiger that this seemed to relate to the compatibility between the user and the magic.
The better the compatibility between the user and the magic, the more likely the control system property would appear in that magic.
From this, Yuri believed that Reiger's compatibility with disintegration magic must be very strong, even though his suitability for control system magic was only second-class, as the fit between disintegration magic and Reiger was independent of his magic system suitability.
