The Room of the April Witch (四月の魔女の部屋, Shigatsu no Majo no Heya?) is a story written by Meteo Hoshizora and illustrated by Chihiro Aikura that was originally used for the TYPE-MOON 2011 April Fools' Day joke. Unlike previous years, it is a short story without any comedic elements. It was later released in booklet and Drama CD format with narration by Sakamoto Maaya.
It follows a witch named April, who will only open her house's door once in a year, on April 1st.
