Murder is the case that they give Arino in this episode as he challenges the Famicom mystery game Hokkaido Serial Murderer: Disappearance on the Ohoutsuku Sea. Watch as he unravels the complicated web of intrigue penned by none other than Yuji Horii... who stops by to help the Kacho put the pieces together!
...Or, at least, to clue him in to the game's most obscure easter-egg.
No TamaGe this time around, but Arino does get to stretch his legs- well, figuratively, at least- with a return visit to AD Inoue's claustrophobic apartment for another round of Shock Video judging.
