Shigenori Soejima’s work on the Shin Megami Tensei: Persona series
The art style of the Persona series is very close to an anime aesthetic. For example the third chapter of the is stylistically close to a fantastical manga, for use of mecha-like Persona and Mitsuru’s flamboyant styling, while the setting of the fourth istallment has its environment and character designs a lot more grounded. Shigenori Soejima also said that for his character designs, Soejima uses real people he has met or seen, looking at what their appearance says about their personality. If his designs come to close to the people he has seen, he does a rough sketch while keeping the personality of the person in mind.
