Strange, I think it is obvious in the screencap of Gold and Red firing the guns that Ryuunosuke lacks his Shinkenmaru:-?
For the Rekkadaizanto picture problem, everyone take a good harder look. . .
EVERYONE but Takeru has their Shinkenmaru on thier holster. This either reeks of bad editing, or another case of Genta pulling it out of his ass.
It sticks out too far to be Yellow's Shodophone holster.
There's actually a little more to that according to the sub on YouTube. Akumaro is trying to create "Hell", the land of ultimate pain and suffering. Creating "Hell", however, destroys both the human world and the Sanzu River so he could care less about what happens to the Gedoushu.
We also learn that Uramasa was born out of the corpses of his family and that Juzo is the key to creating Akumaro's Hell since it requires someone who is Half Human/Half Gedou.
Anyway, my intent was to show that Pink still had hers, contrary to a certain shipper
So Pink has her sword put away, or Blue's got a really awkward erection going on.
You can see a tiny black "T" shape there. That's where you slide in the Shinkenmaru, so I would say it's empty. Compare it to the image below.
