Aw thank you!!! I'm glad you can enjoy it! I actually haven't really made anything about Junior's death in Devilsburger aside from the fact that It Happens and it's kind of a Canon Event so to speak. It's tough because I feel Junior Dying is an important part of his character and how the other characters react, but also of course OG Junior died randomly of dysentery, which Devilsburger Junior would not lol....modern medicine is a marvel...

I guess a statistical answer re "freak health problem" would be something like an AVM rupture, since that's a scary thing that can happens even with young people. More commonly for his age bracket would be something like car accident. A part of Jr's personality I feel from my reading and I think wouldn't be out of place in DBverse would be also a latent suicidal/depressed nature which may be an aspect.

Honestly I've kept it pretty vague on purpose bc 1) I haven't really decided myself 2) since the reason is less important than the impact, the fact that it's a shocking unnerving community event for a beloved if troubled young healthy person.

Also in the pretentious version of Devilsburger where that universe in and of itself is kind of its own Eternal Return construct and a purgatory for the Real Figures lol it becomes like it doesn't matter, everyone is moving along their events and bears to hit in a way out of their control. So Junior Must Die for the narrative and it doesn't matter why...etc etc...but I get ahead of myself.
