Hien

"The Mutant Apes live and die along with the Master. If you want to fight him, you'll have to get through us."

- Hien about Kato

Hien is a henchmant of Kato in the video game Shadow Hearts: Covenant. Hien is frequently by the side of his fellow Mutant Apes Raiden and Ouka and serves his master Kato, loyally.

Hien was injured badly injured but in Shanghai, nearly killed by the Seraphic Radiance. Hien's heart stopped but Kato him medical attention and had him revived. It was said there was no hope and Hien at first but Kato took Hien to get experimental surgery and cybernetic implants that saved his life and completely restored him. After being revived Hien was given training as part of the Japanse Military's new initiative called the Mutant Apes which were to be made up of reanimated undead super-soldiers. Kato was working bringing others completely back from death rather than fro must death's door and in this quest he would come to create Ouka. Hien is the first to greet Ouka when she is brought to life and agrees to help her if she can prove her skill as a fighter to him. After being beaten Hien's loyalty is re-enforced and he becomes just as devoted to helping Ouka as he is to serving Kato.
