Tetsuya Nomura is a character designer turned director. He is best known for designing the zippers and belts (also his fetish) in Final Fantasy VII, IX, X/X-2 and XIII.
Toriyama worshippers are mad at him because they think quantity is more important than quality. However, it becomes "low quality is better than nothing (althout nothing is better than the work of Toriyama)."
Nomura got his ass kicked out of Final Fantasy XV development team because he couldn't finish his job.
