The Rising of the Shield Hero 3 (KYU, Aiya)

Naofumi and Raphtalia do not have much time until the next wave is upon them. As they fight their way through the kingdom, they meet a new feathery companion—Filo! Together, the three travel about Melromarc on a mission to gain the strength they will need to survive the approaching wave of destruction. On the road they level up, become reluctant heroes, and continue to get nothing but trouble from Motoyasu and Myne. Finally, locked in battle with one of the fiercest monsters yet, Naofumi discovers a dark, hidden power.
