About Omoidaise! Kousei Nikki Joon-chan!!
Omoidaise! Kousei Nikki Joon-chan!! is a word-puzzle simulation game in which you complete a diary of things and actions by entering one or two characters into an incomplete word. You help the protagonist, the pestilence god Joon Yorigami, by finding words that make sense in a diary.
For example, adding “ni” to “ka○” completes “kani” (crab), letting you record that Joon ate crab. Some prompts are verbs, such as “ha○tta”: adding “shi” makes “hashitta” (ran), while adding “o” makes “haotta” (put on a haori).
