i think freya call bell einjhar or something Like that

I'm just counting the hours for the Gods to call him "Argonaut" once and for all

Vestal. Purely based on the fact despite having a dozen or so girls chasing after him, Bell is still a virgin.

Knife prince is a good name for bell he get to level 5 or 6

I would prefer to a Flame knife prince to Bell.

Something like paladin or torch bear would work I think and it wouldn't link him to the sword princesses to much I don't really like how much she's training bell men and wemon fight differnt and useing a knife is completely different then a sword she basically would have gotten him killed if this was more realistic
