Development Background 
The author @takanory liked Nekochan emojis introduced in our company’s Slack.
I was a heavy user of emojis and also installed and poromoted Nekochan emojis in related community Slacks 
One day on Shikamatsu-san’s X (Twitter), I saw an example of using Nekochan emojis in presentation slide 
.
“I see… I didn’t know that was possible!” I immediately thought of copying the idea.
But I thought it would be a bit tedious to copy Nekochan emoji images on each slides 
.
I use the Sphinx extension, sphinx-revealjs to create slides (my slides -> slides.takanory.net ). And I use Sphinx Design extension to display Font Awesome icons in my slides.
In the same way, I thought it would be possible to display Nekochan emojis on slides with a simple string (in this case the nekochan roll and emoji name), so I tried to create my first Sphinx extension 
.
I would be happy if sphinx-nekochan could be used to create documents and slides with Nekochan emojis all over Japan and the world
