The monsters "Fur Hire" are anthropomorphic animals wearing armor. They also seem to be inspired by pirates or mercenaries. "Fur Hire" seems to be a pun on "fur" and "for hire", which describes well their beastly mercenary nature.
The main strategy of the archetype is to swarm the field with as many monsters "Fur Hire" as possible, in order to trigger their effects, that range from card destruction to LP recovery.
The Level 4 or lower monsters "Fur Hire" have an Ignition Effect that allows the player to Special Summon a monster "Fur Hire" from their hand during their Main Phase, plus an additional Trigger Effect that activates if a monster "Fur Hire" is Special Summoned while that monster is face-up on the field.

Trigger Effect when a monster "Fur Hire" is Special Summoned
Adds a monster "Fur Hire" from the Graveyard to the hand.
The Level 5 or higher monsters have a Trigger Effect that activates when they are Special Summoned and another effect that serves as a protection against the opponent's actions, by either negating their cards or effects or protecting other monsters "Fur Hire" from attacks or targeting effects.
Excavates a number of cards equal to the number of different monster "Fur Hire" (other than itself) and adds 1 excavated card to the hand.
Discards a card "Fur Hire" to negate the activation of a monster effect.
With the release of the Link Monster Folgo, Justice Fur Hire, Fur Hires now have a powerful board-breaking strategy. By Link Summoning Folgo using non-Beast monsters (Seal and Beat are excellent for this), he can Summon from the Deck Donpa or Recon, who then Summon another Fur Hire from the hand, triggering their effects to destroy an opponent's card, whereupon Folgo will draw 3 cards off his second effect, as you now control 3 Fur Hires. You can even use Mayhem Fur Hire to Summon a Fur Hire during your opponent's turn, interrupting their plays and drawing 3 extra cards during their turn.
Interestingly, in English TCG, every "Fur Hire" card has reversed phrase to mention its archetype card in their texts; instead of using the standard phrase "archetype" card (e.g. "Fur Hire" card), they use the phrase card "Fur Hire" instead. This phenomenon is also reflected in every "Fur Hire" card name, where the position of "Fur Hire" is placed after the noun (e.g. "Rafale, Champion Fur Hire" instead of "Rafale, Fur Hire Champion").
So far, this phenomenon only occurs uniquely to "Fur Hire" cards, since the other new cards released within the same pack as this archetype ("Vampire" and "Sky Striker" cards) still retain the standard phrase to mention the archetype card in their texts and card names.
This could also be a pun to the phrase "for hire", since they are animals with fur and also mercenaries someone could hire.
This deck is the antithesis of the "Sky Striker" archetype, in many ways:
This deck's main strategy encourages filling the Main Monster Zones with monsters, while most of the Sky Striker (Spells) encourage keeping them empty.
This deck's composed of several monsters "Fur Hire", and 3 Spell/Traps, while "Sky Striker" had originally 3 monsters and 10 Spells. (Meanwhile some more "Sky Striker" Link monsters were released.)
This deck has only 1 Extra Deck monster, "Sky Striker" has only 1 Main Deck Monster.
