"WAAAAAAAZZUUUUP!"

Basically Ragnar used Cai for trolling everyone and shitposting.

As douche as he is, Ragnar is formidable fighter with axe as his signature weapon, also loving faithful husband to third wife Aslaug, good father to Ragnarsson but suck at parenting.

Ragnar hates love affair as he remain faithful to last Valkyrie Aslaug, his wife and also volundr partner.
