Rotund-San was a high ranking samurai that was obsessed with food. This was his downfall as he was easily bribed. A master with any weapon, he could remove any opponent if food was offered.
On a very lonely cold night, he was to stumble on a young pup that was on a quest for food. If food could not be found, then he would settle for someone to throw his ball. Both would fight to the death for food, but in a cold and dark ally they would both meet their equal.
A rare find for any scavenger of the night was a bone full of flavour. Fighting a deadly duel for this luxury was inevitable but fight they did. Low Wolf was the winner" as he was the brighter of the souls. Everyone loved Low Wolf. Well, nearly everyone except for one person.
So Low Wolf allowed Rotund to win. Of course Rotund was fully aware of this but it was food. Anyone that gave in was easy prey, in his opinion. From that day on they became inseparable, well apart from when eating.
