The Maelstrom series

A week had passed since then. I was starting to grow used to this new lifestyle in the Silver Garden Academy, and it wasn't much trouble. 

One thing I noticed was that the classes had improved. Now they were teaching more practical things that are directly used in battles. 

At the same time new research was being done on the body of the demon beasts and all the information was being presented to the students in a form they could understand easily and use to know their enemy better. 

Till now they have found out that the weak point of the demon beasts was their cores, however, no one really knew what the cores were since they haven't been successful in retrieving a functioning one. 

Of course, I was already aware of all this information due to the novel but hearing it again refreshed the memories so it was kind of helpful in a manner.
