Perhaps I am overthinking it, prior to seeing them use Reshiram/Zekrom I too would've associated them with UBs. However, iirc in v13(pretty sure that's the first iteration of NM school)Reshiram/Zekrom did not appear, why then was it added as a boss battle against fake Risa/Jean in v13.5?

Just finished a complete run of v13.5(ch1-ch15+renegade route) and there were 3 things that interested me. 1. There's a tendency to group important characters into representing legendary trios such as Creation trio (Tiempa, Spacea, Griselda), Aura trio( Nymiera, Vitus, ???) etc. My point is, in the(not sure if this was in v13) Nightmare School where you're split into two groups Clear/Kieran disguised as Risa/Jean have you fight Reshiram/Zekrom respectively. Clear and Reshiram kinda makes sense as her thing is manipulating reality/truth with illusions. Kieran and Zekrom also kinda makes sense with his whole shtick being Electric types. Kyurem is the one that stumps me, the two candidates are Eden or MadameX. We basically know nothing about Eden and I fail to see how MadameX has anything to Kyurem.
