@Xaiyeon Well speaking of SEGA and blockchain NFT...... they are trying to implement that, but for it's only sonic emojis for now.

In terms of how PSO2es is handled, you can treat it like a "sidestory" or a "side job" for your character as they are present in both stories. As a result, the Guardian has had "more" adventures with other members of ARKS and were part of the "Darker Busters" team in PSO2es where in the main game you simply are one of the two "Guardians."
However, for other spin-offs like Phantasy Star Nova I am not certain if the player can be the same as the Guardian on the Delta Valiant crew as the game's ending is ambiguous and the main game has not really acknowledged that game's lore and world (otherwise I feel Episode 6 would play out differently) and I believe the player is only mentioned in reference during IDOLA Phantasy Star Saga.
It's just I wanted to know about it. So in a way I wanted to see you're answer as well, since you and HarmlessSyan played pso2 jp so.
While I'm not a lore expert within the working of Phantasy Star, But Duemens in pso2 are "draconic like" because of Haddred's death or this case the result of time travel with his handkerchief that he wore that had his DNA being sent back to the past for the creation of the race, and with PSU's (PSP2I's) it's more has to do with the fact that they are a mutation from the SEED incident.
I'm going say this in here, you should go to command prompt and launch it as administrator, then type in sfc /scannow in the command prompt and press enter then you going to wait abit to finish.
after then see if that can fix the reference_by_pointer BSOD for you.
