Can someone explain the back up story in Issue 5?

For the longest time, I thought that Bishamon was the actual character you played with. But from reading this story, I understand that Bishamon is actually the samurai and that the samurai armor is called ‘Hannya’. Is his story like Nightmare’s Soul Calibur story where Siegfried/Bishamon takes the sword/armor but becomes possessed?

Also, who is this Oboro character? In Vampire Savior, sometimes you fight him after your final opponent. He looks like a glowing Bishamon.

I haven’t read issue 5 myself but just by the anime series that Capcom produced a few ears ago, that was the tale in itself. It’s demonic armor that takes possession over its wearer, but only those that are strong enough to control it. Otherwise it consumes their body and kills them.
