Warning before noon
The story takes place on May 20, 2012. Renman and Narumi each received news that Myu would be killed on the top floor of the Integral building at noon that day. The two rushed to the scene, aiming not only to protect the girl but also to stop the second solar eclipse plan that could destroy the world.
Dual protagonists and unknown abilities
Renman is a high school student, Narumi is a special police investigator. Their identities and information differ, yet they are brought to the center of the incident by the same warning. The appearance of someone at the scene using the unknown technique "Ψ" pushes the case beyond the scope of an ordinary crime. The story unfolds the mystery step by step from the perspectives of two characters.
Production and series locations
The original concept, script, and script supervision were handled by Kotaro Uchikoshi, with character design by Yu Takikawa and bomi. At launch, it was introduced as an integral series title, simultaneously announced as a PSP port of the Infinity series titles. The narrative advances through suspense through skill, investigation, and event structure.
Original and PSP additions
The PS2 version was released in March 2008, followed by the Windows version in April of the same year. The 2009 PSP port added opening credits, opening and ending songs, and added about ten event images. These visual and musical additions belong to later handheld versions, so the original story and initial release records should still be viewed separately.
Searchers and stagnant worlds
According to the 2008 4Gamer character introduction, an email from Narumi's colleague Makoto Yukizumi led to an investigation by Public Security Section 12; Mei Kiridera led the Ψ Criminal to hunt down Mew. After Renmaru and Myu escape from Integral, they meet Maina, who arrived two days early in the stagnant world, and Yuu Hoshino, the leader of Mirage who sees this place as an utopia.
Two perspectives and answers section
4Gamer explains the structure as two perspective routes: Renmal and Narumi, then moves on to the ∫ Answers section. The first half simultaneously advances the actions of the two protagonists.
The final chapter of the Rengan Divagate branch
In the Divagate branch, Makoto shoots Renman and Myū, and the second Eclipse plan is executed; The finale also shows the two promising to accompany each other under the annular eclipse.
Windows version: Search in the Empty City
After Renmaru and Myu escape from Integral, they find the streets empty. While searching for the city, they meet Maina.
Windows version: Tasks for viewpoint routes
The route is divided by the perspectives of the two protagonists and the ∫ Answers chapter, rather than independent endings where each female lead can be pursued. Some of the questions raised by Narumi Viewpoint will be left for ∫ route to be revealed; During Integral's rescue scene, she also tried to stop Mei but was thwarted by Ψ.
