Wistoria: Wand and Sword 9 (manga)

The new, magical dungeon-adventure fantasy series from the author of Is It Wrong to Try to Pick Up Girls in a Dungeon? Seeking to fulfill a promise to a childhood friend, Will Serfort enters Regarden Magical Academy with the goal of making it to the top of the magical world. There’s just one problem: he can't use magic! Will his sword skills be the key to unlocking his true potential? ONWARD AND UPWARD Thanks to the last-minute awakening of Will’s mageblade, Regarden emerges bloodied but unbroken after the attack on the Terminalia. Yet victory is bittersweet, for Rosti made the ultimate sacrifice, and Will lacks enough credits to advance to the Tower.

Only a miracle could keep his dream alive now as graduation day approaches...
