Infinity Nikki has a bunch of different types of quests that can be done. Following the Main questline will progress you through the story, unlocking various main outfits and guiding you through the world. One of the more curious types of quests, Random, are ones you need to stumble upon to unlock. The best way to do this is to be aware of the people around you and look for question marks or exclamation points, and interact with those people.
Here are all of the Random Quests we've encountered so far in Infinity Nikki
Lost Diary Quest can be obtained by talking to the confused man, by the riverside, in Florawish. He has a top hat on and has lost his diary, which a cat grabbed, that's on the roof of the house he is staring at. It's very simple to obtain this and complete this quest.
Leaf Littler Cleanup Quest can be found around the area of Lost Dairy Quest Quest - if you run through a pile of leaves, you will get Leaf Little Cleanup. You will need to find Monaco near Ray and Wing's to complete this quest by helping him pick up leaves.
Kindled Inspiration: Yesteryear's She Quest is found in Florawish - you will need to wear a specific skirt and talk to Alber, who is looking for inspiration or a new hairstyle. You will obtain this quest by talking to Alber, who is looking at a statue sort of near the Daisy Inn.
Folklore Guide Quest can be unlocked by going near Ciceto, who has a Box Game. He wants to know more lore behind it. This will then track how many box games you do and win, giving you better prizes when you've completed milestones. Box games normally give out some bling and crystals. Box games are found all over the map.
Observation: Ancient Statue Quest can be found after helping Kilo the Cadenceborn. Once you leave the area, walking back down the steps he was blocking, you will find a person there. He will ask you a question about what is broken in the statue you just saw by Kilo. The answer is the head.
Kindled Inspiration: Blossom Walk Quest can be found near Daisy Inn. If you leave the Daisy Inn and go to the left, there is a lady in her garden, tending to plants. You need to wear specific shoes and talk to Narci, to inspire her.
Observation: Activity Centre Quest can be found in Breezy Meadow. You will need to talk to Aventura, to prepare for a trivia quiz from Professor Aventura.
Photo Investigation: Family Search Quest can be found after the power outage, by walking in front of Rhett (or at least, that's what triggered it for me!) You need to find and talk to Ocheno and his family.
Photo Investigation: Animal Trail Quest can be found when you first see a Bibcoon outside the Chuckle Club. You need to talk to Avaro and find the animals within his photo, like a Hidden Object game.
