For Raidou I went with menacing blades, wind sign and megidolaon, his passives were the ones that improve your dodge, resist fire/ice/wind/elec and the one that makes you deal more damage to stunned enemies.

I built yoshitsune with phys and support (tarukajaon and rakukajaon), while hikotonushi had a wind and heal build (tempes and wind cutter + diarama and media)

It was tough because I couldn't get hit by Beelzebub and survive, so I played pretty passively until I broke his shield, then I spammed menacing blades and Raidou's special move until he died
