Majo demo Steady  

魔女でもステディ, My Steady Is a Witch

One morning, a man named Hisashi Seki wakes up with an unfamiliar woman in his bed. Although surprised, he is pleased by the situation and enjoys it to their mutual satisfaction. However, her appearance causes strange occurrences that escalate. The root cause of these phenomena can be traced back to Jungian psychology. Asami, whom Seki has named, comes from a parallel universe where people's ideal partners - anima or animus - exist. Her desire for him allowed her to cross dimensions and be with him, but her presence in his world disrupts the natural order. She returns, leaving Seki to travel to her realm to save her. Despite their hopes, things do not go as planned. In the end, they are reunited.
