No one could use the exact same pseudonym in this app, and if they clashed with other existing names, the system would remind them and suggest adding some numbers or other things.
Thankfully, no one had taken Mariella and Byron's pseudonym, so they successfully changed their account's name.
After that, Mariella took a picture of the starry sky above her along with the huge tree behind her and used it as her profile picture.
At the same time, the old man used the photo of his magic book cover with the same starry sky in the background as his profile picture.
This magic book was an item from the system's mall and it was pretty common, but it would also reveal the clues related to the host's original world somehow.
But since old Byron was also someone with a magic power, he wasn't too intimidated and didn't really care.
