I don't exactly understand how their "power" is working.
Are they all able to fly, transform matter and move objects the same way ? I thought some of them could only do one of those thing: Satoru is good at throwing rocks and shaping mirrors

, Maria can/could fly pretty good, and in the last episode (20) i just noticed Saki is also able to rise in the air, and pretty high.
I'm asking because i remember Satoru was teasing Maria in the first episodes, about how bad she was at mastering a specific aspect of her cantus, but maybe it was only because they were just children back then.
Now that they're adults they all have access to the full library of skills ?
