I recall some WN readers saying this MC is from the "cute is justice" school of reasoning, hence his preference for a cutesy/girly look.
It provides an interesting contrast to the MC from Only Sense Online, who tended to whinge and complain about how girly his avatar looked - this one fully embraces it.
One thing the merchant mentions in the WN that she did not here is that :
the rabbits try to run away from anyone over a certain level, so they are not hunted extensively after that level, which is why the gear (and it is a full set, with set completion bonuses) is not really known.
