Haru to Mahou no Kagi

Haruka is a clumsy and somewhat foolish girl who constantly struggles to do anything right on her own. Because of her frequent mishaps, she relies heavily on the support and assistance of her friends to get through everyday life. Her ordinary routine takes an unexpected turn one day when she finds herself trying to escape a group of mischievous children. Desperate for a place to hide, Haruka ducks into a storage locker inside her classroom, hoping to wait out the trouble until the bullies move along. However, this seemingly ordinary hiding spot harbors an extraordinary secret: the locker serves as a hidden gateway connected to an entirely different world. Upon stepping through, Haruka discovers a mysterious realm far removed from her familiar school life. It is here that she encounters a character named Milk, as well as a strikingly handsome boy named Leon. To Haruka's astonishment, Leon is not a stranger at all—he is the very same captivating figure she has repeatedly seen in her dreams, blurring the line between her sleeping fantasies and this breathtaking new reality.
