The World's Strongest Rearguard: Labyrinth Country's Novice Seeker Vol. 4 (Manga)

Thanks to a severe wound, Arihito is all too aware that his rearguard powers have one major flaw: He can’t use them for personal protection! Now it’s up to Kyouka and the rest of the party to support him, but can they overcome the Field of Dawn’s mighty gatekeeper, the Giant Eagle- Headed Warrior? Victory would mean discovering powerful secrets about the world—including the reason they were all brought to the Labyrinth Country in the first place!
