This feat makes zero sense in hindsight
Base Raian casually catching a blow from a bloodlusted Rei is an insane feat that almost feels like it was retconned immediately afterwards considering how even Mokichi was able to surprise and tag Raian several times in their fight. It also makes Rei look like a complete chump that would get easily beaten by any of the top tier KAT entrants, which we know is not the case.
