Kingdom Hearts 3D: Dream Drop Distance
According to Joshua, Shiki and the others lost their existences and their souls were taken by the Reapers, but they were revived in Traverse Town and met with their partners. To return to their world, they must complete a series of games created by the Reapers.

Shiki first appears being attacked by Dream Eaters, but Riku comes to her aid. After saving her, Riku attempts to leave but Shiki tells him that he should accompany her and protect her, calling him a "knight". Reluctantly, Riku agrees and they travel together until Shiki runs off and Riku meets with a mysterious man in a black coat. It is later revealed by Beat that the man in black tricked Shiki, telling her that if she brought him Riku, he would take her and her partner to their home world. Realizing that she was wrong, Shiki apologizes to Riku. Later, Shiki, Beat, and Riku watch Neku, Rhyme, and Sora on another Traverse Town, which was split in two by the mysterious man.

Later, Shiki is finally able to reunite with Neku. When they are about to take a break, they are attacked by Dream Eaters, but are saved by Sora. When Sora introduces himself to Shiki, he tells her that Neku was looking all over for her and that he said that he "needed" her, embarrassing Neku. However, Shiki thanks Neku, claiming that she was happy to be important to someone. Joshua appears before them and tells them that Riku and the others are fighting in the other Traverse Town, so they go the Third District to fight the Dream Eaters. However, a Dream Eater runs away to another world and Shiki wonders if they failed their mission, to which Sora says that he will find the Dream Eater for them. After thanking Sora, Shiki mentions that Neku has changed for the better. Along with the rest of her friends, she invites Sora to visit them in Shibuya one day.

Origin
Shiki Misaki is a character from Square Enix's . During Neku's first Reaper Game, Shiki meets him at the Statue of Hachiko and makes a pact with him. Though Neku is at first resistant to her, she constantly remains a source of positive support for him, as well as a teacher of the value of friendship and how the Reaper Games work. After a series of missions, Shiki's normal upbeat disposition was shattered when she and Neku encountered the Game Master, Yodai Higashizawa, who points out the jealousy in her heart. Due to this, Shiki becomes unsure and unfocused for the sixth day as she reveals that her entry fee was her actual appearance, and that body she appears in is actually that of her best friend, Eri, who made her feel inadequate. After learning that Eri felt as envious towards her, Shiki reveals her resolve as she and Neku defeat Higashizawa on the final day. However, only Shiki could be revived; the Reapers tricked Neku in using her as payment to enroll in the next Reaper Game. Feeling guilty, Neku decides to win this game to save Shiki.

During the third Reaper Game, Shiki was used by Megumi Kitaniji to attack Neku and Beat before the former manages to destroy the Red Skull pin controlling her. From there, Shiki joins in the final battle with Kitaniji before Joshua reveals the Conductor's true goal was to save Shibuya. In the aftermath, back in her true body, a revived Shiki meets Neku, Beat, and Rhyme at Hachiko.
