Koji Ishitani has announced his resignation from Monolith Soft.

The news comes via a Tweet posted on Ishitani personal Twitter, where he confirmed his departure from the company. Most recently, he was the co-producer of Project X Zone and Project X Zone 2.

Ishitani worked at Monolith Soft for roughly sixteen years, where he was involved with a number of games, including: Xenosaga Episode I, Project X Zone, and even Baten Kaitos: Eternal Wings and the Lost Ocean. He went on to thank his fans, as well as the people he worked alongside throughout the years.

Ishitani is the second high-profile staffer to leave Monolith Soft this past weekend, as Project X Zone director Soichiro Morizumi also confirmed his leave from the company.
