Synopsis

Shirone, after experiencing strange nightmares and a concerning photon output during a test, decides to join the Science of Supernatural Spirits Research Group. This is fueled by a desire to understand and fight against the supernatural rather than be afraid. The group enthusiastically welcomes Shirone, but unbeknownst to them, Professor Ethella knows about the 'Infinite Domain' that Shirone entered and the danger it poses to his very being. Shirone's experience is theorized by the group to be connected to ionized souls and the ability to transcend time and space, similar to a previous experiment.
