Trivia[edit | edit source]

  • A picture of Akikawa Valley can be seen on the corkboard at the Date Residence. It's directly pointed out by Mizuki Okiura during her exploration in PSYNCIN' IN THE CAPTaiN.
    • The Date Residence is first explored on Day 4 (youdAI or jukkAI) in Branch A of the story and on Day 3 (gyoukAI) in Branch B. In Branch A, Date is told about the Original Cyclops Serial Killings and Akikawa Valley on Day 3 (syokubAI), and the picture was most likely added during the night between Day 3 and 4, where Date most likely returned home for the night. In Branch B, Date is never told about the Original Cyclops Serial Killings, yet still has the picture of Akikawa Valley on the board. It's unclear if this means that Date looked into the Original Cyclops Killings on his own during the night between Day 2 and Day 3 (between keitAI and gyoukAI) of Branch B, or simply that there was no need to reconstruct Date's home for a minor detail that couldn't be examined in-game.
