Few days left before the fight but still i have not seen the odds for this fight, excited to see who is the favorite and to what extent.
Yes, the odds are still not out even on some boxing analysis-related websites.
And as usual, in crypto bookies, we can expect this fight to be listed at least a day or two before the official fight date. But I'm thinking if is there any possibility that this fight won't be listed in crypto bookies? I just think of it now because in the past, where PH boxers are involved even in a big title match
e.g Magsayo vs Gary Russell Jr., Casimero vs Rigondeaux, etc. even how big the event is, they were just listed a day before the right. Since this fight between Casimero and Akaho doesn't really have an impact, might not be considered listed by crypto-bookies.
Of course, just my guess.

Yes, obviously this fight is going to be listed 24 hours before the actual fight, I don't want to speculate here specially it involved PH boxers.
I will just say that maybe there is no hype in this fight or any other fights that PH boxer is involved, that's why the odds are not released early. And it's on a lower class, usually this fight doesn't get the usual love from any betting sites unless it's really hype name involved.
So we will wait mate, probably it's Casimero that will be the favorite but we are all looking forward to maybe what will be the odds on the under/over rounds and KO.
Maybe on the day of the fight we will see available odd from the bookies, so far there's no available yet and like you mentioned the recognition on the international world might not be appealing that's why bookies is not providing early odds for this upcoming fight, Casimero might be a star but in this new division, he just a beginner and Akaho is not that well-known so there are just few gamblers who are waiting for this betting odds.
