Len'en anniversaries are celebrated every year on the 11th of November, because this is the date the Len'en Project was born, in the year 2013. Usually during this time of the year, JynX will post an illustration on pixiv and thank the Len'en fans for all their support towards the project. So far, they've created four illustrations, along with a transcript of a conversation amongst some of the Len'en's characters.
