The magazine praised the title's "traditionally-Vanillaware graphics" and character animations as well as its online mode, stating that "The easy entry into online play is just as great, and raising characters to send to the battlefield is both innovative and very smooth in action. This game gets top marks in fun." It also garnered an 82.5 out of 100 average from "Dengeki PlayStation" magazine based on four reviews of 90, 80, 80, and 80.
