Academy's Genius Swordmaster

Ronan emerges from a catastrophic war against giants as the lone survivor of the imperial army. But the victory is hollow; as his commander, Grand Marshal Adeshan, lies dying, an even larger enemy armada descends from the skies. Seeing a final spark of hope in Ronan's unmatched bravery, Adeshan uses her ultimate magic to send him back to the past. Reborn into his younger body, Ronan is determined not to waste this second chance. He enrolls in the elite Phileon Academy to hone his skills and become the greatest swordmaster the empire has ever seen before the giants return.
