Your card has been dealt.

So the only problem with the MAPLE theory is the name. Interesting, haha I'm quite convinced that Su/Lotus is the Legend now, especially since (s)he went missing around Demon Slayer's time. Orca/Orchid said she was serving as a replacement, iirc. And that picture with the brightness up is pretty convincing.

This is taking from the definition of the justice card from the fool's journey

The Fool must now decide what this vision means to him personally. He looks back over his life to trace the cause and effect relationships that have brought him to this point. He takes responsibility for his past actions so he can make amends and ensure a more honest course for the future. The demands of Justice (11) must be served so that he can wipe the slate clean.

This is a time of decision for the Fool. He is making important choices. Will he remain true to his insights, or will he slip back into an easier, more unaware existence that closes off further growth?

the choice mentioned may be that lotus/su will finally reveal himself to the world that he once was the thief hero that escaped from the dark magician's magic. Being a master of disguise through the fate of his cards (if this makes sense), he was able to disguise as orca's twin (but not really her twin) and fooled everyone. seeing that the union is rising against the dark magician, he takes initiative to give them insiders and aid to fight the dark magician. with this theory, the update can also bring new contents as lotus/su lead the union to the area surrounding the dark magician's lair, and possible hint at the pirate hero since the dark magician can have some info on him
