Interesting discussions. Reminds me of sudden weird NPCs showing up out of nowhere. Example would be the guy at the Land of Chaos during the Main Quest.
I don't know about the story of that NPC (and I didn't play Toram at that time), but I heard that it was made by(?) the old MC named Sekai no Suzuki. Later, he retired as an Asobimo staff and the boss never appeared again. It was when Toram was still in an early release
I got stuck early on in the MQ, when you need to asl around for clues on Holy Gems. I kept trying to talk to the Holy Gem vendor, a Cule in mage robes, who is just sitting there. He's right there. He sells Holy Gems. Please.
Yeah, they are also really friendly to their players, especially with the Japanese community (since, well, they can only speaks Japanese). I kinda hoping they would do the same with the ouside-of-Japan players too, but I think that would be too much to ask for XD
