HIKAGE NO AMIR: TSUIHOU SARETE MUSOU SURU SAIKYOU YUMIZUKAI

Amir Waker is an archer who’s been banished from an S-Rank party "The Band of Prodigies", which mainly consisted of nobles. He then falsified his identity and registered himself as an F-Rank adventurer. He took an escort quest to the countryside. The quest was supposed to be an easy task for him as a former S-Rank. But surprisingly, the client of this quest is none other than the 3rd princess who’s being targeted for some certain reasons! Will Amir be able to escort the princess safely from the "strongest" knight’s division of the kingdom? Amir is thus dragged into the political struggles and conflicts of the kingdom. — Description from AniList community (anilist.co).
