Jacket Design Information


Hello jubeat fans♪

I'm tQy.

I unreasonably forced T_da to let me make many jackets for this game.
I made this and that, here and the--re.
You wouldn't know for sure.
My art style isn't unified...

So for polygon, I tried to make a girl using modeling for the first time. With polygons.

Since it was my first time doing this, I had many enjoyable memories making her skin color a bit more vibrant, while searching for boys' many desires and tastes. That picture is still on my desktop...
That's creepy~




As expected, that's creepy. Hey you...

Chart Production Information


Hello, I'm isonin.

Since this song can be unlocked in the 2nd STAGE of copious travel, I made the notecharts easy enough to be groovy and enjoyable.
When you find all the sounds, you'll think "I don't know what I'm hitting!".

Since this song's development and characteristics are clear, I smoothly completed the charts as I wanted them to be.
Or rather, I did a small dance.
Is this what you meant when charts naturally come to mind... master MUSCLE....
