In this ceremony, Rio Tenjo and Kikyou Tenjo have to battle each other with swords. A fateful event occurs at the ceremony and Yuto ends up living with Rio.

Denikeri is Windmill's eleventh game after Shukufuku no Campanella and its life began around February and March 2009 at an internal staff meeting over what Windmill's next project should be. At the meeting, there were a lot of people that wanted to create a game that was set in a school. Coincidentally, after the release of Shukufuku no Campanella, the Windmill staff received several requests from players that also wanted a game that was set in a school setting. With the fans' requests matching the staff's own desires, designing and planning for a new project began in earnest. From there, the staff began removing elements such as "magic" and "supernatural powers" and then proceeded ahead with creating a story that could potentially happen in the real world. The producer of Denikeri is Chatora. The scenarios of Denikeri is being written by Tahei Hirauchi who have previously worked on Prism Ark Love Love Maximum. The music of Denikeri is being composed by Ecnemuse. The art and character designs for Denikeri will be provided by Kōcha and Yū Narumi. This will be the first time that Narumi will be doing the art and character designs for a Windmill game. Kōcha provided character designs for Kikyou Tenjo, Misono Misono, and Haruka Tomone while Narumi provided designs for Rio Tenjo, Komachi Suzueda, and Yuzuna Kaede. With regards to the character designs, both Kōcha and Narumi stated that they were pretty much free to design them however they pleased.
