Sanae Higashihongan (東本願早苗 , Higashihongan Sanae) is a ghost who lives in Corona House room 106. She insists that she must wait in said room until her parents come back, having driven out every room 106 tenant with mysterious phenomena in the past. As a result, the room gradually became cheap. Later, she safely merged with her real body,but lost her memories of the time when she was a ghost. When she regained her memories as a ghost, their personality hadn't quite blended in. This makes it look like Sanae suffered multiple personality disorder which is Sanae-chan(Ghost) and Sanae-san(Human). However, they shared memories and still liked and hated the same things, so it could still be argued that they were one. She later joined the Satomi Knights as a houseworker helper[1].

So, Nana used magic to connect her and her father, this makes her survive for time being while Nana and her mother Kanae pursue the magician. after retrieved focus gem that stored Sanae's spiritual power that converted into magic power. Nana managed to save her life for the moment but she won't be able to live long due to a lot her spiritual energy were unable to attach to her properly.

Several years prior the story Sanae admited to The Kisshouharukaze municipal hospital due to unknown disease and grown weak, but the real reason that she's weakening is her leaking spiritual energy[2]. Her parent later move from Corona House Room 106 to Higashihongan family resident since it was closer to the hospital where she treated. The leaked spiritual energy in Corona House Room 106 later turn into an 'artificial ghost' with separate conscious from the original and drive out every room tenant with mysterious phenomenon so her parent can come back there. this causing the room gradually became cheap.

When ghost Sanae merged with her human body and regained her memories, their personality hasn't perfectly blend. when she's with Koutarou and the other she was bright and cheerful, and when she was not, she was withdrawn. According to Kiriha, her personalities would eventually blend into one between the modest Sanae-san and active Sanae-chan [3].

Powers & Abilities

Having been born into a long line of shrine keepers and priests, Sanae was born with an immense amount of spiritual energy. When in her astral projection form, Sanae is capable of many ghost related abilities such as intangibly, being invisibility to normal people, telekinesis, will-o-wisp and possession. By clinging onto someone, she can share their senses: either allowing her to taste what they taste or allow them to see people aura's like her.

After returning to body, Sanae temporary lost her memories as a ghost and didn't know about how to uses her abilities. Although she could still see people aura's and other ghost. Once she regained her memories as a ghost, she became able to use spiritual energy while in her body. She could strengthen her body and even generate a bow and arrows using her spiritual energy. She can do astral projection her ghost form at will (which is dubbed Sanae-chan), although her body becomes lifeless until she returns to it. By volume 14, Sanae can astral project without her body becoming lifeless by using a spiritual wire between her ghost form (Sanae-chan) and her living body (which has Sanae-san's personality).


Koutarou Satomi

At first, the two didn't get along because they wanted to drive each other out of Room 106. The two started getting along a little better after forming a truce due to the growing number of invaders. Eventually, Sanae came to love Koutarou and started to see him as the most important person in her life. She would cling onto him more often and take his side in matters. While she was a ghost, Koutarou would only allow Sanae to possess him so she could taste what he is eating, and even to use his body for games and for warmth when she gets cold in her sleep. Their relationship is compared to a little sister looking up to her big brother, with Sanae seeing Koutarou as a ideal man and wanting to become a ideal woman for him.

Her relationship with him slightly differs when she splits, Sanae-chan having the casual relationship she has with him, while Sanae-san is more shy towards him.
