Over at Atlus' official Shin Megami Tensei IV website, we get a glimpse at some artwork for the game, showing off the five samurai heroes and what are possibly their respective demons. The art is done by a variety of artists, a good chunk of which have worked on the Kamen Rider franchise. Fans may be able to spot the influence.
King Asmodeus was designed by Yasushi Nirasawa, known for his Undead character designs in the Kamen Rider franchise. Dragon God Kouga Saburou was designed by Tamotsu Shinohara, also known of Kamen Rider fame. Archangel Rafael was designed by Keita Amemiya, who did character designs in Clock Tower 3, Onimusha 2 and 3, and monster designs also in Kamen Rider. Earthquake Kuebiko was designed by Kyouma Aki, known for his demon designs in the Persona anime spin-off, Persona 4: The Animation. Finally, Heavenly God Omoikane was designed by special effects and makeup effects artist, Yoshihiro Nishimura.
