Something curious about the issue of the Dark Meister and her obsession with Curry is that it could be a reference to Episode 30, where Yuamu vs Zwijo took place. To remember, in that Episode, Yuamu got everything that she needed to participate and win the Curry contest. She went to the bakery to claim the prize, but it ended up being Zwijo's bakery, who had the contest promotion. They both have a Duel since Zwijo did not want to respect what he established in his contest and ends up winning the Duel. However, in the end, they both decide to make a deal: Yuamu would take all the Curry she wants from Zwijo's bakery on the condition of not revealing Zwijo's location. Something similar happens here: Zwijo wins a Duel to deliver a Curry to the Dark Meister. This only adds fuel to the theme that Dark Meister has Yuamu's personality and ideas. Why do they want Curry? No idea, but it seems to be related to Earthdamar. However, I do not rule out that it is a special Curry since they are creations of CPT, who is an AI created with quite special materials. PS: I think Zwijo indirectly warned Yudias to be careful with Contact Fusion when he brought Dark Matter Requiem. Likewise, we still don't know anything about Contact Fusion and if there is a background for this type of Fusion Summon.

I think you have to remember that all the Darkmen have only been around for about a month. Therefore, they do not have much experience or know almost nothing about the "World of Light". It would be difficult to believe that the Darkmen were powerful Duelists if they only existed for a month: it would sound somewhat artificial. On the other hand, Zwijo already has Dueling experience, so it's not that difficult for him to get some wins. The stranger here is the Dark Meister since she, in theory, should also be a month old, but she was able to defeat Zwijo. Therefore, the Dark Meister must have gained Duel experience in that period of time. Fun fact: Dark Matter Requiem will be the most used Fusion Monster in Voidvelgr Deck since it is the only Fusion Monster that is easy to bring to the Field. In fact, its Effect is not a big deal, but it serves to overcome Stun/Defensive strategies. It doesn't help that that Fusion Monster doesn't have any kind of special Protection (many Fusion Monsters in Rush Duels are more powerful than Dark Matter Requiem)
