For the past five years, VisualArt’s have released the visualstyle CALENDAR each year, featuring artwork of Key characters for each month of the year. For 2015, the art will be sampled from the most popular illustrations of Angel Beats! -Operation Wars- and Little Busters! Card Mission. The VisualArt’s store has begun accepting preorders for this item, priced at Â¥2000. You can check the item description for estimates of when the product will be shipped to you (no earlier than the 28th of December).
