Secretly A Powerful Magician

"UGH!!!!!" I said, i was so tired from the test and we have new assignments already? This is much more worse than college!!

Hello! My name is Sasha White but i died after the plane that i was in crashes. My new name now is Sierra with no surname i am not a noble but a commoner that was lucky enough to get in this magic academy.

"Sis-- i mean Sierra let's go the head magician wants everyone in the main hall."

This is my older brother Matthew in the past but his name now is Blake. He was my older brother before i died and reincarnated here and was still my older brother here. He died with me in the plane, it was a trip we both were waiting for but it ends with disaster.

Now we are staying in an unknown world where there's magic, our journey together will be long but if we have each other we can achieve victory in the end.

If we are that smart or predict what the enemies do or don't, so i suggested to keep a low profile but a mage saw us in a pond using mana, he took us in the academy and suggested us to the head mage.

And that is why we are here....
