Promise of Wizard (魔法使いの約束, Mahōtsukai no Yakusoku) is a Japanese online simulation video game created by Coly. It was released for Android and iOS devices in November 2019 in Japan.

A manga adaptation with art by Uta Shinonome was serialized in Ichijinsha' josei manga magazine Monthly Comic Zero Sum from April 2020^[1] to December 2023 and was collected in three tankōbon volumes. A second manga adaptation with art by Shibatarō Nakamura has been serialized in the same magazine since April 2024.^[2] The game also received various stage play and radio web drama adaptations. An anime television series adaptation produced by Liden Films is set to premiere in January 2025.

Promise of Wizard revolves around the Sage, whose name and gender can be changed by the player, a human from modern-day Japan who has been summoned into a world where wizards and magic are real by a group of wizards known as the Sage's Wizards. The Sage's Wizards have been summoned by previous Sage's and must join the fight against the Great Calamity, the name for their moon, which descends once a year, causing havoc with the strength of its magic. The Sage's Wizards prior to the player character have lived apart from one another, only convening when it is time to fight the Great Calamity. At the start of the story, they have faced an unprecedented tragedy where half of their number died in the battle and must rely upon the new Sage (and the mysterious powers only the Sage has) for help in next year's battle.

There are multiple formats of stories used in game, including event stories, main stories, anniversary stories and card stories.The event stories focus on the Sage and a selection of the twenty-one Sage's Wizards as they train, negate the damage from the Great Calamity through missions, and deepen their bonds with each other.

Promise of Wizard begins with the player character being summoned into the world of wizards as the battle against the Great Calamity has finished. They are greeted by soldiers of Central Kingdom as well as the Minister of Magical Affairs, Drummond, and the secretary of Central Kingdom, Cock Robin. They attempt to persuade the Sage into joining them in order to bring the Sage's Wizards under Central's control but fail when two of the wizards (former Central knight Cain and Eastern noble Heathcliff) appear and ask the Sage to trust them. Cain explains how the Great Calamity was stronger this year than it ever had been in the past.

The Sage is brought to the Magic Manor where one of the wizards, Heathcliff's mentor Faust, lays dying. Tapping into the power of the Sage, they are able to revive Faust before he turns to stone, the result of a wizard's magic crystalizing upon being dealt a death-blow. The next day, the Sage agrees to perform a ritual to summon wizards to replace those who were killed by the Great Calamity. The majority of the Sage's Wizards convene - with the exception of the strongest wizard in the world, Oz, and the three younger Northern wizards; Mithra, Owen and Bradley - and Cain proposes that they all live together at the Manor in order to better prepare themselves before the next battle.

Meanwhile, Central kingdom prepares to hold a parade to honor the Sage's Wizards for defending the world, though it is marred by the suspicion and prejudice held against the wizards, heightened by the fear of the strength of the Calamity. Strange events and rumors plague Central kingdom's capital, including reports of seeing someone in the graveyard at night. Upon investigation, the Sage's Wizards discover the cause of the Great Calamity's increased strength, as well as the mastermind behind it - a mysterious figure named Nova who has been using human remains in a ritual in order to summon the Calamity closer.
