Last week on Friday, Nippon Ichi opened a new teaser website in Japan for an upcoming game. Today Nippon Ichi updated the website and the characters pictures has been changed to “7” and there is an “E” letter at the right side and you can listen a new BGM too.
The 7 maybe means that 7 days left and we will get more information on January 19 (or maybe not).

The URL also changed from 170106 to 170112. Until more information, please stay tuned:
