The 100-page book also features guest art by sports manga author Kenji Minomo, comedy author Yasuyuki Tokumitsu, and wrestling manga author Kouji Sakana, as well as interviews with pro-wrestlers Keiji Mutoh, Danshoku Dino and Ai Shimizu (also a voice actress!), along with the makers of bishoujo wrestling mobile game Ring Dream.
You might also remember that, back in February, Shiwasu no Okino did Trigger’s monthly site illustration in honor of the 19th’s Wrestling Day.
