All the Anime have pulled off a great coup for fans of Full Metal Panic! - the creator, Shouji Gatou, will be attending London MCM Comic Con on May 25th - 27th 2018.
During the visit, he will be signing merchandise and discussing his work with fans, so you will have plenty of opportunities to meet him at the show.
This is a tremendous opportunity and All the Anime should be given full credit for making it possible.
You can read more at the official All the Anime blog, which includes a short biography.
