Elizabeth Leiston, the daughter of Haldoria's powerful prime minister, is the picture of a refined noble lady and the perfect future queen. But when her fiancé publicly humiliates her, calls off their engagement, and starts spreading nasty rumors about her, Elizabeth reaches her breaking point. Why should her only friend be her loyal maid, and why should she continue to serve a country that doesn't respect her? Elizabeth concludes she won't stand it any longer and will bring down the kingdom, even if it's the last thing she does! As such, she uses her quick wit and, more importantly, her seven magic grimoires to embark on a quest for revenge. And let her tell you, there will be hell to pay! (Source: J-Novel Club)

Second season of Tsue to Tsurugi no Wistoria.

Fifth season of Kanojo, Okarishimasu.

Fuu Nonoyama and Rui Nonoyama are sisters from a land of magic, who were once on terms with one another, but have drifted apart. Suddenly, they are given magical powers by two cat-like spirits, Uguisu and Azuki, allowing them to transform into magical girl idols. However, there is a catch: these powers only last for a year and they cannot tell anyone that that magic exists. While neither Fuu nor Rui knows one another are magical girls, they soon begin their careers as idols. (Source: Wikipedia)
