According to Yukito Ayatsuji's information he caught in a gossip magazine, the well turns you into evil and if a person makes a wish in front of it, evil will be bestowed upon them, and no matter what crime they commit, they will never be punished. When Tsujimura and Ayatsuji went over at the well's location, they found six round pebbles and four bamboo leaves. The diameter of the well is measured 74 cm and when the sun is at 68 degrees, the edge of its light reaches a depth of 183 cm.
