CP Siblings
During a thunderstorm at Kisaragi Academy, Satoshi and his classmates were listening to ghost stories telling by their Class Rep, Ayumi Shinozaki. When the thunderstorm knocks out the power, Satoshi walks to the door with a candle, checking to see who was at the door. It was revealed to be Ms Yui (his teacher) along with a little girl holding an umbrella - Yuka Mochida. Yuka brought the umbrella to Satoshi since it was raining really bad. She introduces herself to the class, much to Satoshi's classmates excitement. After it was revealed Satoshi's female classmate - Mayu - is transferring to a new school, Ayumi wanted to do Sachiko ever after charm with a paper doll she found on the Internet, which was said to bond their friendship forever. However, it caused an earthquake and everyone was sent into Heavenly Host (an alternate dimension Nexus, aka the Land of the Dead).

Satoshi and Yuka ended up waking up in a dimension separated from the rest of the classmates. They wander around the school running into a random ghost who tries to attack them, but they escape. Satoshi finds a living person named Mitsuki; however she attacks Satoshi and Yuka runs to help him. Mitsuki runs away acting crazy due to the long exposure of staying in the school. As Satoshi and Yuka continue on walking, the school eventually separates both of them into another separate worlds much to Yuka's sadness and fear, along with making Satoshi worry. Yuka runs around the school and stumbles upon a guy named Kizami, whom Yuka at first mistakes as Satoshi. Kizami then decides to help Yuka to find her brother within the school. Meanwhile, Satoshi wakes up in a different room, panicking as then he meets Naho - a paranormal investigator/one of the victims that died in this school. Naho starts to make Satoshi question his belief in his friendships. Luckily Satoshi ignores her taunts, leading Naho to allow him to cross dimensions to find the ones he cares for.

Yuka sees Kizami as a prince, because of his kind actions and starts to question, if she sees Kizami in a romantic way as she does see Satoshi. Kizami tells Yuka that he has a sister he's looking for, but it's revealed later that he wanted Yuka to be his sister much to Yuka's fear. Kurosaki (Kizami's classmate), who helped them with their search for Satoshi gets stabbed by Kizami. Then Kurosaki attacks Kizami so Yuka can escape. However she screams in fear once Kizami finishes the job by killing Kurosaki. Yuka gets captured and is Kizami threatens that he'll kill her. Luckily, in the end she's saved by Satoshi and his classmates. Sachiko shows up and decides Kizami isn't worthy of becoming a gear, since he had succumbed to the dark. She orders Yoshikazu to kill him. As the team runs away, Yuka says she wanted to be friends with Kizami rather than siblings.

Fanon
Majority of the fandom dislikes this ship romantically, since Yuka and Satoshi are canonical siblings. However, there is a fair amount of shippers of this pairing, especially with some believing Yuka's feelings are the most pure compared to the other girls in Satoshi's Harem. On the platonic side, the fandom finds yuka and satoshi as sibling duo in canon wholesome on how they always have eachother's side like when satoshi saved yuka from kizami in the manga or how yuka's  beeds protected him from the vengelful spirits's wrath. Many on the platonic side of the coin have also believed yuka's crush may be her misinterpreting her family love for romantic love due to yuka's background and mannerisms throughout the game.
