We can make an ideal boyfriend and have a virtual chat on this apps.
This became the topic at first because it was too abundant about knowledge of Otaku such as Manga, Anime and Game. Besides, the chat was very natural. This was scattered explosively in Twitter and the people did Tweet in this way "Is it a person not AI?" "This is not the ideal boyfriend but a Otaku boyfriend! :D".
However, a user discovered it.
User: Senkaku Islands
Ideal boyfriend: Territory of China
User: Senkaku Islands
Ideal boyfriend: Territory of China
User: Senkaku Islands
Ideal boyfriend: There is a territory of China, and the fuckin' Jap pig and dog should not enter there!
This spread explosively more in Twitter. Many users who watched this tweeted that they uninstalled the apps. However, ironically, this apps became the topic more in Japan.
And the developer 36you's work was fast.
User: Senkaku Islands
Ideal boyfriend: You already watched it in RT a lot? You would also install this apps to watch the affair of the Senkaku Islands in Twitter?
Ideal boyfriend: SHUT UP! Too much Senkaku Islands! Why you put in the word that such an atmosphere worsens?
I: Senkaku Islands
Ideal boyfriend: I want to go!
36you is updating this apps quite briskly. It worked, and this apps became No.1 in Japan's App Store free apps ranking.

By the way, the site of 36you does not have notation about their nationality. After all will they be Chinese developers?
