I Was Banished Because They Said Water Magic Was Useless Nero was branded incompetent and expelled from the hero’s party simply because he was a user of water magic, which is considered the weakest type of magic. However, Nero has a talent for quick thinking and clever ideas, allowing him to use water magic in ways no one expected. Before long, he starts defeating enemies one after another in an unbelievable show of power. Along the way, a cute slime that affectionately cries “Spii!” becomes his companion as well. Even while everyone around him keeps doubting that “water magic is the weakest,” Nero proves them wrong by crushing his enemies one after another.
