Sakura Momoko no UkiUki Carnival (さくらももこのウキウキカーニバル) Ending and Staff Credits (initial run)
Starting the carnival. I borrowed from various YouTube and NicoNico videos online as a basis to help when I was stuck, so the characters at the carnival I recruited from following a mixture of those playthroughs. Also if you're stuck on the Shinka and the Fireworks Offering, you can get one of the stones(?) for the fireworks shop by loading one of the web pages for a map layout, revealing it as a hidden (shining?) item. Also you probably don't need to, but make sure you finish all the chat conversations with characters and good answers to get their emails that they will be attending the carnival. Sorry for the vague wording, I notice lovevictini in the "Longplay of Sakura Momoko No UkiUki Carnival" got stuck on the same thing.
