Wazamonogatari , the second light novel volume in the "Off Season" of NisiOisin 's Monogatari Series is getting a mobile game tie-in. The website will formally launch on January 30, but is currently hosting a Super Mario spoof video depicting Koyomi's sister Karen Araragi hitting a block that rotates out the kanji of the series' previous novels. When the block displays "Waza," Shinobu and a donut come out of the block like a Mario power-up mushroom.

Two more "Off Season" novels will follow Wazamonogatari titled Nademonogatari and Musubimonogatari . Both novels are slated for this year, but the novel did not note the order of their release. Wazamonogatari was released in Japan on January 13.
