DUNGEON DIVE: Aim for the Deepest Level Volume 13 (Light Novel)

My name is Liner Hellvilleshine, and I am the sworn knight of Sieg. After returning from a year in the Dungeon, I resumed my duties as a knight of Whoseyards, diligently carrying out a secret mission entrusted to me by Lastiara. The objective: Recover the blood of Saint Tiara that was flowing within the Jewelculi. With that mission nearing completion, all that remained was to await the resurrection ritual. But then, a person claiming to be Saint Tiara herself appeared before me, telling me to receive the blood into myself. She told me to aim for the deepest level of the Dungeon. I stepped from the Eleventh Crossroads of Whoseyards and into something else entirely.
