And for the sixth one, you need to go to Shibuya Island and defeat Gojo, or the Limitless Sorcerer. The only downside is you have to wait around 5 minutes for him to spawn, and since you need to fight him multiple times, it can take a while. So to make it faster, I recommend server hopping into low-player public servers, so the boss is still available and hasn’t been killed yet. This trick is actually really effective and saves you a lot of time.
