It's Ryuu's birthday on March 13th. Preorder the Priroll cake and macaron set by March 6th 2024 (JST). For more info about the cake and macarons, see this post.
Is it blasphemous to say that I can only truly appreciate IoRyuu with Akoya in the mix? AkoIo all the way, baby!
Also, as I am a 2nd years enjoyer, I want to draw them all together one day. I just didn't have the heart to subject the twins to these three's gayness when I drew this.
