The second season of Monster Strike, which was entirely animated using computer-generated imagery (CG), follows Mana Livingston, a transfer student from America, as she befriends the main characters and learns about the popular game Monster Strike. Throughout the series, Mana obtains her own ring and partner, joining forces with her new friends to solve crises that arise when energy points attract monsters to various locations in Japan. By sealing these monsters, they are able to prevent them from being drawn to these areas any further. However, it is revealed that Madarame, the CEO of a company reaching out to children, has been withholding important information from them.
