The plot thickens! It seems like our hero has activated their ham radio and is trying to send a message that's as cryptic as a Japanese proverb. "10121.0 CW" sounds like a code name for a top-secret mission, perhaps? Or maybe they just want to announce their presence in the Sefuri Hokusan Prefectural Nature Park with a fancy radio signal. Whatever the case, it looks like someone needs to decode this message and save the day!
