SG SCRATCH: Astral Guardian (19 JUNE 19 - 11 DEC 19)

[Nyansan]

It appears Regius Pose is in fact a Katana pose and not a Sword Pose even though Regius is a Hu Sword user.
Good Job Sega.

In their defense though, Regius is canonically a katana user. The NPC Regius running around just so happens to be using the sealed form of Yonohate (the 'sword' form) but storywise he's a katana user (unsealed Yonohate and his new genesis weapon Tsukuriyo are both katana, not to mention Azanami was trained by Regius in using katanas)
