Afterplaying Teddie’s, Labrys’, Junpei’s, Yukari’s, Yu’s and Sho’s Arcade Modes, there’s a few things about this/these character(s) that I could piece together already.
First of all, surprisingly…
Sho’s Arcana is “The Sun”. Not “The Moon”, as previously suspected. (This says nothing about SHO MINAZUKI, though.)
For further information on this guy (of which I’ve gathered plenty so far), please follow me under the cut.
