A Story Where Books Hold Magical Power

Adapted from Kadokawa Shoten’s popular novel, Whoever Steals This Book tells the tale of Mifuyu Mikura, a high school student from a family of passionate book collectors who surprisingly hates books. When a thief steals from her family’s legendary library, Mikura Hall, an ancient curse is unleashed — forcing Mifuyu to enter the very stories she’s always avoided to save her town. With the help of a mysterious boy named Mashiro, she embarks on an adventure through enchanted tales where fantasy and danger intertwine.
