Hello I'm new here and I'm currently trying some Konquest speedruns. (I'm playing PS2 PAL)

I found a very interesting thing: after defeating Darrius in the main quest, the next objective is shown to be Hotaru, and talking to him makes him run away and disappear, saying he'd meet Shujinko in Outworld, however this dialogue is technically non-mandatory: if you go to Outworld after defeating Darrius you already find Hotaru in Lei Chen, and talking to him makes the game progress as normal from there. The most interesting thing about this is a bunch of events that were supposed to be triggered by said dialogue and instead don't happen, for example there still are all the Tarkata outside the city walls, and in Orderrealm the people in the prison don't disappear. Also after beating the game you can meet Hotaru to train in his fighting style, but there still is the other Hotaru walking back and forth, waiting to be talked to! Pretty funny.

Now, from a speedrunning standpoint this doesn't seem to help much, you literally just skip that one dialogue, so my question is: would this be allowed in a NMSNG run? I don't think it's a "major" skip, and I don't believe it technically counts as a glitch, I'd classify it more as "sequence-breaking" but Idk, I'd be ok for it to not be allowed either, it's not a big loss.
