At first I thought Sentinel will release this one back to back with Soulgain last year but it seems they are still prudent enough to let the SRW fans wallet to recover. It has been around 6 months since the initial reveal but Sentinel is finally ready to announce the next SRW Riobot, Vaisaga! Scheduled for September 2025, Riobot Vaisaga will be sold for 39600 Yen.
Vaisaga is the second Shadow Mirror mecha to get the Riobot treatment after Soulgain. In SRW OG it is a Secret unit usable by Lamia if you fulfill certain condition but back in SRW A it is the Super Robot option available for both Axel and Lamia. Just like Soulgain, Vaisaga is a close combat monster who had a bastard sword as its primary weapon. Despite it is not as accomplished as Dygenguar in OG verse, Vaisaga is still quite a powerful Swordmaster type mecha. While Sentinel might have decided Raioh as the next Riobot candidate, I am quite sure that other Shadow Mirror mecha have a good shot coming up like Angelg. Though Vindel's Zweizergain would be awesome as well if Sentinel is interested in giving it a physical rendition.
