The Shinrabansho Collab is returning to Puzzle and Dragons with some minor upgrades and evolutions. Unfortunately, it is mostly a story of too little, too late to have any real viability outside of Kiriko as a powerful sub on the new Xiang Mei . Even with the introduction of a re-coloured (non-awoken) Sakuya , Sonia , and Athena , the quality and quantity of the rare rolls is horribly lacking. The cards are quite underwhelming and it would be wise to not roll as you are more likely to pull more Uriels , Gadius , or collect enough MP for another Xiang Mei before rolling Kiriko (or anything of real value).
As with any Collab REM, any monster who can achieve at least a 5-star rarity can qualify as an assistant for Skill Inheritance. Therefore, you should think carefully before hastily selling your rolls. If you have not already, I highly encourage you to read my Skill Inheritance Guide.
