[Maskad]

Some romanized names in the booklet are surname first, given name second, separated by a comma, others don't have a comma. M-4.11 has both: 玉川 紗己子/Sakiko Tamagawa is listed as "Tamagawa, Sakiko", while 桜井 芳樹/Yoshiki Sakurai is listed as "Sakurai Yoshiki". Both have artist pages, but aren't linked yet and Sakiko Tamagawa also has the comma in the credits section, indicating she were two people.
