I'll reply to the rest after this. Here is, AFAICT, the entirety of the evidence available:
- Ukyo ran some number of enterprises that held assets of others
- Those enterprises have folded
- Creditors of these enterprises have not had their assets returned
- Ukyo has not communicated his position, plans, nor intents to these creditors

OK, what am I missing?

Based upon that evidence, the only rational conclusion is that Ukyo has absconded with the assets, and has no plans to return them.

Of course we do have SebastianJu claiming to be in possession of some secret insider knowledge about Ukyo's true heart. Irrelevant. Inadmissable as hearsay.

As I have said before - honorable people who owe creditors do not avoid informing those creditors.
