■ Comment from Yuki Kaji

“Thank you for waiting! The 2nd ‘SoyogiCon’ is finally here!

During the first contest, so many more people participated than we could have ever imagined, and the number of wonderful works created remains fresh in my memory. I was especially happy to see how much potential and charm of ‘Soyogi Soyogi’ was brought out, and I felt great significance in the creative expansion that could truly be called ‘Fractal.’

To further support everyone using the software in their creative activities, we’ve now made it possible to commercially distribute your works through TuneCore Japan.

With this opportunity, I hope you’ll consider ‘Soyogi Soyogi’ as your partner in creating a new era of entertainment!

I’m sincerely looking forward to your entries for the 2nd ‘SoyogiCon’!!”
