Not every party treats you like a hero—especially when you’re a lowly red mage like Yuke. So, after years of constant ridicule by his A-rank party members, he ditches them. Searching for a new party, he reunites with former students Marina, Silk, and Rain, and joins their group. But on a quest to conquer the world’s greatest dungeon, they become entangled in chaos that threatens the world.
