Yuusha Party wo Tsuihousareta Seireijutsushi: Saikyou-kyuu ni Kakusei shita Fuguu-shoku, Shin no Nakama to Godai Dungeon wo Seiha suru

“Endless Wings” – an elite party conquering dungeons at the world’s forefront. Among them is Lars, a spirit mage who supports his allies by commanding invisible spirits. But when party leader Kristoff accuses him of being dead weight (since no one else can see his spirits), Lars gets expelled. At his lowest point, he meets the Spirit King in a dream, who warns him of the Demon Lord’s impending resurrection after 1000 years of slumber. Now, this disgraced mage must rise from rock bottom to become the world’s unlikely savior—as a new adventure begins!
