Personally, this was very sad news to hear.
Artist and painter Hirō Isono, who worked on the Mana (Seiken Densetsu) series of video games, passed away on May 28 due to heart failure. Isono was born in 1945. A memorial service was held on May 31.
Isono graduated from the Aichi University of Education’s fine arts department in 1968, and has worked as an illustrator and painter since the 1970s. He has worked on both picture books and light novels during his career. In 1991, he provided the main visual for Square Enix’s Final Fantasy Adventure (Seiken Densetsu: Final Fantasy Gaiden) game. He would continue providing illustrations for the series including Secret of Mana (Seiken Densetsu 2) in 1993 and Heroes of Mana (Seiken Densetsu HEROES of MANA) in 2007.
