Dainichi Nyorai

Dainichi Nyorai (大日如来), also known as Dainichi (ダイニチ) and Senju (センジュ), is the Guardian Ghost of Sati Saigan. He is also one of the avatars of Lucifer.

About
Long ago, Lucifer produced avatars (Senju included) to seek out the truth of various myths about herself in human world.

Dainichi first met with Sati when she was talking to a wooden statue of him and was approached by the Land Owners of the temple she was in. When she could not pay them, they suggested that they could take her instead, but was stopped when Dainichi suddenly spoke. Using the statue as a medium, he threatened to beat them up with his many arms and broke the statue to reveal himself and scare them away. Dainichi affectionately refers to Sati as "Sacchan".
