Though English seems to be the main world language nowadays, seemingly for otaku the world language is Japanese! Recently an online conversation in Japanese between a Pole and a Taiwanese guy about experience with models drew interest from Japanese netizens. Sure enough, Japanese should be the universal language; after all, even in a fantasy world, speaking Japanese can come across.

On the surface, this is just a conversation between two Twitter users, one called Yaruku, one called Opechan, discussing experience with purchasing models, but a closer look at their identities and you'll find...
(There's a picture of Yaruku's Twitter profile) Yaruku is Taiwanese!
Yaruku is a Taiwanese doujin artist, who has participated in Fancy Frontier and in the Touhou Adorned Sakura Festival (note: literal translation, could find no English name), and has most recently been applying his talents to the World of Tanks scene!

And the other person...
Opechan is Polish! (there is a picture of Opechan's Twitter profile)
Opechan is a Polish otaku who loves military hardware and models, and created the Polish doujin circle Poland Doujin carrying forward military knowledge!

The public conversation between these two in Japanese unexpectedly became a talking point among Japanese netizens. We can only say, sure enough, Japanese is the international language of otaku!

（ﾟ∀ ﾟ） Even elves and fairies speak Japanese these days, what's so strange about a Pole and a Taiwanese guy doing it?

(Note: This last bit may be a reference to fantasy anime where the protagonist gets sent to another world where they somehow speak Japanese.)
