They were retrived and their bodies augmented with machine parts - as well as possibly simian body parts.
Later, having procured the Émigré Manuscript, Kato used one of the rituals to "grow" Ouka - a clone of the late Yoshiko Kawashima - and artifically speed up her development. She had the least augmentations, and was herself a living weapon.
They were given titles reflecting their augments;
- Ouka with her visor - See-No-Evil.
- Hien with his lower-face covering - Speak-No-Evil.
- Raiden with his earprotectors - Hear-No-Evil.
Whiles possessing their own strengths, all three were hardier than normal humans, and also shared an absolute loyalty to Kato.
The Foreign Minister regarded them as non-human, and reminded Kato to not get involved with them on a personal level.
The project and group ended following the deaths of Dr Hojo, Kato, and the Mutant Apes.
