I like to think that Hyoudou is old age Akagi completely driven crazy by his monster luck, skill and lust to see people bet their entire lives in a single gyanburu
The nose knows.
Old age Akagi mellows out and kills himself because he gets Alzheimers.
Not a bad idea OP
In the only gyanburu he ever lost, he bet his nose, and it got smashed in.
it all makes sense now
Akagi took a trip to space so he can't be.
And Osamu is Tonegawa. Osamu spent his entire life trying to be like Akagi/Hyodo and subsequently became his right hand man.
