Longtime Final Fantasy art director Isamu Kamikokuryo has left Square Enix, after a little over 18 years since joining the company in 1999.

Isamu Kamikokuryo worked as an art director for Final Fantasy X (background art director), Final Fantasy XII, Final Fantasy XIII, Final Fantasy XIII-2, Lightning Returns: Final Fantasy XIII, and Final Fantasy XV. Outside of the Final Fantasy series, was also art director for The 3rd Birthday.

Here’s what Kamikokuryo shared on Twitter about his resignation:

“Yesterday, March 31, I resigned from Square Enix. It’s been a little over 18 years since joining the company in 1999. It was a wonderful experience, from starting out as a concept artist for Final Fantasy X to Final Fantasy XV. I feel nothing but gratitude for the company that provided me with the opportunity to meet so many people and display my talent.”

“Although I feel as if I left my heart behind, I want to move forward onto drawing new things. From here on, I’ll do freelance art and diction work, and I’m thinking about reviving some writing activity as well. To all the staff, and to all the fans, thank you very much for supporting my drawings for such a long time.”
