LilimPlanning notes
The staff boss list (dated 7/16) has a demon Jimenez (悪魔化ヒメネス, race 超人) on the L and N routes (an Awake in the finished game), and a maybe second fight on the N route. A third area maybe row, ヒメネスの悪魔, is a fight you cannot win against a demon that "later becomes Jimenez's mascot".
