Guilty Gear is a really cool series of fighting game with an amazing art direction and soundtrack. The characters are all unique in both design and gameplay, and the lore is so complex I wouldn't be able to explain it here at its fullest.
There's both a wiki for mechanical information (Dustloop) and for lore (Guilty Gear Wiki)
If you want to get into the series, I recommend both Guilty Gear Strive if you would prefer a more modern and simpler approach to the gameplay, or Guilty Gear XX Accent Core +R if you want a cheaper option that goes on sale for under 5$ and has a deeper mechanical complexity.
I also love the fanart community online, so I'm gonna post some of my favourite pieces, click on the pictures to check out the artists
