Hi, not sure if you still respond to ask but as a fellow Reiji fan, I was wondering, what do you think Reiji's deck says about him as a character? Not just the overall corporation vibe, but the mismatch of history, mythology, and science that his monsters are based on.
Yeah I still respond to asks, don't worry ^^
and I love that you question me about this, because for starters I don't think his deck theme is mismatched at all, if anything I think the only mismatched theme of his is the one that reinforces his CEO role, because among my many headcanons about Reiji, I think that he never wanted or was even interested into becoming a CEO at all, and less so at such a young age, and in fact among other headcanons I have is that after the series finale he temporarily steps down from the company and Himika is the one taking the reins from then on, so he can have a normal life for a little bit.
but that wasn't your question, it was about the part of his deck that seems mismatched.
Basically I think of this as proof that Reiji is at heart someone who enjoys the pursuit for knowledge, by having an cards, which he created, based in mythology which imo goes hand in hand with history, it shows his interest in learning about how people thought and explained things they couldn't make sense of, so they imagined these gods and creatures who dictated the fate of humankind sometimes showing mercy and granting boons and others being cruel, petty and using people as their personal playthings, I don't think it's a coincidence that most of the mythological inspirations are from monsters who loved to wreck havoc, like Brownies, Lilith, Lamia, Gryphon, or that are connected to entities who would bring misfortune or the end of the world like Pandora, Typhon or Baphomet, other cards are straight up named after events that will bring or announce the apocalypse, like Kali Yuga, Deus ex Machina, Requiem, I don't think these ones are big brainers, he lived his childhood and teens with the fear that his own father would bring about the end of the world he knew and he needed to stop him, in fact, all the mythical knights and kings in his DDD archetype, I don't think they symbolize his role of CEO, I think they symbolize him trying to construct himself after these heroes who defended their land and protected everyone.
Then you have the other part of his deck, the one that's named after famous scientists and some science tools as well, because I think, that this is where he found his answer, in the face of dealing with a potential war with actual monsters brought to life with Solid Vision, he saw the light at the end of the tunnel through science and technology, into preparing himself and the city for the attack, and really, overall I think he was an inquisitive nature that leads him to seek answers, we could call this the scientist part of him, I think that even in an AU where he got to have a more normal life, with his parents and Yuya still created the pendulum summon, he would have still been able to crack the mystery and been able to reproduce the type of cards.
Now, you could just say this means Reiji's true personality below all the fanfare of being a CEO, hero, leader etc, it's him being a huge nerd, a scholar at heart, someone who would be more at home in a library or a lab than in an office.
