Miyama Shaei

Miyama Shaei (美山写影) is a student of Matsuume Elementary School and an esper of unknown level specializing in predicting events through photographs.

Appearance
Shaei is a ten-year old boy with light-colored hair and dark-colored eyes depicted as having white pupils. He wears the uniform of Matsuume Elementary School, consisting of a matching colored blazer and shorts, as well as white socks, leather shoes, a randoseru and a round hat. According to Shaei, he prefers wearing the winter uniform over his shorter summer uniform.

Personality
Despite being an aloof boy that shows few emotions, Shaei is comfortable with strangers, although he often refers to acquaintances without any honorifics, much to their chagrin.

Dream Ranker Arc
Shaei has been actively submitting his predictions on the Treasure Hunter App during the latter days of September. At this point, all six of his latest predictions have come true, including an incident on September 25 and another on September 27. On his seventh, he watches over the incident from the top of a high-rise building, and he witnesses how Judgment's Shirai Kuroko and Uiharu Kazari were able to stop one of his predictions from happening. Shortly afterwards, he is confronted by Kuroko, prompting the boy to introduce himself as the creator of the Treasure Hunter App.

In the Judgment headquarters in District 7, Shaei explains his involvement with the incidents uploaded to the Treasure Hunter App and his ability to predict events in the future. Shaei aims to look for someone who can help him prevent the incidents he foresees from happening, and he sees Kuroko as someone capable. However, with Kuroko unable to grasp the situation, he is met with doubt. This doubt was eventually dispelled by Shaei when he decides to use the ability in front of them, allowing for Kuroko to once more save someone's life due after the boy pinpoints the location of another accident waiting to happen. As a result of this, Kuroko and Shaei form an informal partnership that aims to locate and intercept any mishaps Shaei foresees through his ability.

Abilities
Shaei's unnamed ability allows him to predict events in the near future by generating photographs through an instant camera. The image produced through this method has an unrecognizable marbled pattern, which is further analyzed using a research institution's specialized equipment. The analyzed image often contains the exact moment of the incident alone, though Shaei can increase his focus and include the date and location of the incident by shining a penlight through his eyes before making a prediction. The photos generated with this "second stage" of his ability can be then analyzed by an app developed by a company for Thoughtography users in a similar way as in QR code.

Any event that is predicted by Shaei's ability is known to happen at a 100% success rate, with a ten- to twenty-minute offset from the event's predicted time. Shaei himself cannot prevent the incidents he predicted and it will only happen elsewhere within the timeframe of his prediction, unless someone with an ability that manipulates more than three dimensions, like Teleport that uses 11th-dimension calculations, intervenes in the predicted event.

Shaei's ability detects dangeous events close to him more easily, similarly to danger sensing abilities, but it's not triggered by events under a certain level of danger like the Vento of the Front's Divine Punishment-induced comas as they didn't bring enough harm to the affected people.

This prediction ability in its "second stage" is severely taxing to Shaei's own body, causing him to bleed through his nose and weakening his stamina on every use.
