Can confirm on the "araya" thing, it's a mispronounce of "oraa ya" ("it's me" in dialect). It's similar to how the practice of saying "moshi moshi" when beginning a phone conversation started because kitsune can't pronounce the word twice in a row.
Fun fact, the Irish Gaelic wording for otter literally translates to "water dog" and Irish lore about otters is noticeably different from that regarding Japanese otter lore
@Bloddrake I used to have that problem and I think it is related to IBD, but isn't present in everyone or at all times. It was the sign that mine was getting worse. IBD sucks because there is no treatment while if its IBS there is treatment. IBD is jsut too fucking broad and crazy, but the most important thing is that you stay regular. Optimum is shitting once per meal, but once a day is good enough imo
