Shout-outs in cards

[Furo]

Have you noticed that each card theme has two shout-outs to a hero of another game? One is on the deck box (visible when you select Karma level) and another one is the second-to-last theme treasure.

The first theme refers to Foure the super-fluffy dog from Chroma Quaternion.
The second theme refers to Alice the literal sword girl from Sword of Elpisia.
The third theme refers to Leila the wall from Miden Tower.
The fourth theme refers to Felix the cat Light Deity from Asdivine Heart series.
The fifth theme refers to Enah the energi gynoid from Alphadia and Alphadia Genesis series.
