At that time, all our practical courses at Sage Academy were based on each student’s aptitude. Although the general technique for using cantus was the same, there were hundreds of levels of difficulty, from simple force exchange to something as advanced as cold fusion. Most of the class was somewhere in the middle, though there were some students who were able to tackle much harder techniques.
Shun’s progress was far ahead of the group. He was working on hatching a chick from its egg in under two hours, an incredibly difficult task since it normally takes an egg twenty-one days to hatch. In other words, he had to use his cantus to speed up the development of something he couldn’t even see by a factor of 250.
To be given permission to use cantus directly on a living being requires not only technical skill, but also recognition of outstanding character. In other words, there were incredibly high expectations for Shun in the future.
Unexpectedly, Satoru was also part of the advanced group. His talent was in reflecting and manipulating light, and his task to create a mirror out of thin air was one of the most difficult skills behind Shun’s. I’ve mentioned this before, but creating a lens out of a vacuum to magnify a distant image was something on the level of Shisei Kaburagi. Satoru’s technique of using water vapor in the air to create a wall to reflect light was considerably easier than that though.
On the other hand, the skill I was working on was reasonably difficult, but much more boring. I had to fuse together a broken glass vase. Maria was working on full-body levitation, making her the center of everyone’s attention. Mamoru was…actually I can’t really remember what he was doing.
“Saki, check it out.”
I looked up and saw an amorphous silver mirror floating a meter in front of me, reflecting my expression of intense concentration.
“Isn’t it kind of distorted?” I said shortly.
Satoru, who had been expecting me to praise him, gave me a sulky look. “No way, it’s perfectly flat.”
“My face isn’t that sunken in.”
“What? Isn’t it your heart that’s distorted here?”
With that snide remark, Satoru retreated. The mirror melted into thin air. After that, every time I wanted to talk to Satoru, I noticed him sneaking closer to Shun, watching him from behind.
