Trinity Seven, Vol. 10: The Seven Magicians — Kenji Saito

It's time for the main event of the school festival: the Magic Research Battle! All of Trinity Seven (plus Arata) are arming themselves for battle against tough opponents from the rival Royal Magical Academies, but first they'll have to face...each other?! It's a knock-down, drag-out fight to the finish with only one team left standing!
