I'm sure we now see the new background today (which is probably connected to the new clan at the end of the month). What do you think the story could be? According to the game's Instagram (https://www.instagram.com/urbanrivals_official/) and ArctoPicto will have a hand in the story line. Also, there's this line: "it wont be usual. but it will be linked to urban rivals better than last ones."
The hex pattern at the top reminds me of a few different things: Alien Invasion, Virtual World, and bees. Since we already have Sakrohm as the alien clan and I'm pretty sure we aren't going to have an entire clan based off of bees, it might be the virtual world. I could imagine something with the X Virus materializing and beginning to invade Clint City in some fashion.
The other thing that hints at this is the color scheme of the background. The main colors are blue, green, and purple, which somewhat correlate to the general color schemes of the second wave Lds. Aviria Ld has a lot of blue in her art, Nega D Ld has a lot of green in his art, and Ashikaze Ld and Raser Ld have a lot of purple in their arts.
Also, is there a specific reason why the Uppers' sign is lit up and stands out? Maybe it has to do with Nega D Ld? I really don't know.
Does anyone else have some other ideas?
