I’m a little disappointed Unica isn’t a Keter Deck, it feels more like a standard Genesis deck than anything else. It would be interesting if Sofie’s deck changes nations in a future anime after her fights with Raika. Liael swapped nations from Keter Sanctuary to Dark states, let’s do the opposite for Unica, give her some normal units that are regarded as criticals for her skills, and have effects when bound.
Personally I don't really like how sort of gave more depth to Sophie this way. Makes sense as a classic character archetype, strongest gets bored at the top and is also a bit crazy, and I'm not saying she can't have more depth as a character. It just didn't quite stick for me. I think it was the execution a the end and lack of build up. She was never truly pushed in a fight, her backstory hardly explored, and a lack of any grounding traits. Still wish she had a fight against Masanori. It is kinda sad, cause other than Gui I actually liked most of the uniformer's character arcs, especially Jinki. Halona was just a lonely kid trying to do what she thought was correct, Masanori and Tohya's relationship was complicated and entertaining, especially their fight, and Jinki always had that spark since his fight against Michiru. One of the best fights in the season showed just how much Jinki loves this game, and how he wanted to help fighters around the world, misguided through he may be. Praying for him in the Fated Showdown, cause I bet someone will be sent to the shadow realm in this one.
