The series is illustrated by Hitoshi Ariga, a professional artist best known to Pokémon fans for his work as an illustrator of Pokémon Trading Card Game cards since 2011, and as character designer for main series Pokémon titles since 2013's Pokémon X & Y. Outside of Pokémon, Ariga is known for his extensive work with the Megaman franchise, where he has illustrated numerous manga and artwork going back to 1994, as well as his work on the manga for The Big O franchise.
