Here is this month's MONTHLY NAUGHTY ILLUSTRATIONS, "ONLY MY FANS - A Report on the Buzzing Drink'". The energy drink is a thing that appeared in the manga, "IT'S JUST TAKING A VIDEO". The pink vibrator is the one that appeared in Ichikawa's old manga "Shomonai Occhan (meaning "dummy old guy" in Kansai, West Japan, dialect). Ichikawa-do Honpo in deed a mysterious erotic goods company!
*Honpo = central brunch, head office, main store. Also, "Do (dou or doh, 堂) in Ichikawa-do means "office", "studio", "company". Actually Katsushika Hokusai's studio had a name, "Netsu-Tetsu-Do (Hot Iron Studio). Interesting.
Anyway, you can purchase the digital ver. of the "Shomonai Occhan" from here (only Japanese ver. available). https://ichikawado.booth.pm/items/212494
