Ido Front (fan translation: Idofront), also known as the Forward Operating Base, is a research station located at the bottom of the 5th layer. It is the deepest a person can go and still survive the curse. It is the place where White Whistle Delvers begin their Last Dive.
It was here that Bondrewd brought Nanachi, Mitty and other children to act as his test subjects, and where Nanachi and Mitty were transformed into Narehate after ascending from the Miniature Garden of Dawn. It is also the place where Bondrewd raised Prushka as his adopted daughter before turning her into a cartridge.
- Based on a comment from Majikajya stating that Nanachi is a Narehate of the "old ritual site," it is possible that the rituals that took place at Ido Front long ago involved an individual receiving the blessing. How the blessing was achieved by the ancient people is unknown.
