Puchi Nikki (プチニッキ) is a Japanese fangame made by Neji (Pixiv) in SmileBoom's Puchicon app (otherwise known as Petit Computer in other regions) for DSi.
Due to that application no longer being available (at least in the North American region's 3DS eShop), few people are able to obtain and play it.
This is not to be confused with the other Puchicon-made YNFG of the same name (but in Hiragana).

How to play:
- You need to scan everything on both images in the post with Petit Computer.
The current version for 3DS is incompatible, as it does not have a feature that scans QR Codes.
