Hitomi Tsukishiro may be the child of a family of witches, but after losing her ability to see color, she also lost her sense of magic. Nothing has helped her regain that gift until Hitomi's grandmother sends her back in time to 2018.

Despite the kaleidoscopic magic ingrained in everyday life, Hitomi Tsukishiro's monochrome world is deprived of emotion and feeling. On a night as black and white as any other, amidst the fireworks spreading across the sky, Hitomi's grandmother Kohaku conjures a spell, for which she has been harnessing the moon's light for 60 years, to send Hitomi back in time to the year 2018 when Kohaku was in high school. Hitomi's mission seems unclear, but her grandmother assures her that she will know when she gets there. Following a trip through time aboard a train driven by a strange yellow creature, Hitomi finds herself in stoic artist Yuito Aoi's room, and his drawings flood her world with color. What is Hitomi's purpose there, and why do Yuito's drawings return such breathtaking color to her drab world?—MAL Rewrite

Although Hitomi lives in a world filled with magic and fantasy, she can only experience its many marvels in a dreary palette of black and white and grey. She does remember seeing color when she was very young, but the hues and vibrance faded away as most of the people who were important to her left her life. Her emotions have followed suit, becoming greyer, darker, and muted, until even the wonders of becoming a Mage and growing into a teenager rarely affect her. But Hitomi's grandmother has a plan to use a spell that would send Hitomi someplace where the two of them can meet... only this time, her grandmother will be 17. Join the journey to 2018 and witness the hidden powers of love and friendship as Hitomi's journey unveils the mysteries of IRODUKU: THE WORLD IN COLORS.—Sentai Filmworks
