The Corrupt Guildmaster is Beloved by the Banished

"I'm exiling you from this guild!! —But I've prepared a new career path where you can make the most of your abilities!!"

Act, an adventurer who once experienced the bitterness of being exiled from his former guild, decides to establish and manage a new guild called "Heaven-sent Gem." However, because Act exiles so many members, rumors begin to spread in society about a "corrupt guild master"... Surrounded by unique companions like a cool puppy-like maid, a tomboy princess, and an overpowered hero, the (supposedly?) corrupt guild master continues to assess, nurture, and exile people every day!!
