After the first few Gamma attacks, Onari decides to make the temple into a paranormal investigations office, Mysterious Phenomenon Institute, to better aid in Takeru's quest to find the Ghost Eyecons and stop the Gamma by having citizens around the city report strange events to them.
- The Daitenku Temple is named after the Tenkuji family.
- The Daitenku Temple is in actuality the Kōgon-ji Temple, a temple in Shimotakase, Tomioka, Gunma Prefecture.
