The official twitter account for Nisio Isin’s Monogatari anime series is currently teasing a second collaboration between the Monogatari series and Sanrio’s mascot, Hello Kitty. The first Monogatari x Hello Kitty Cafe collaboration was launched back in December to promote The Guest Cafe and Diner at Shibuya Parco.
The new teasers show Black Hanekawa, Shinobu Oshino, and Hitagi Sinjougahara wearing some type of Hello Kitty merchandise.
According to the announcement, Seven Eleven will be releasing new Monogatari x Hello Kitty merchandise in their convenience stores this October 2015.
