Higeki no Genkyou to Naru Saikyou Gedou Last Boss Joou wa Tami no Tame ni Tsukushimasu. Anime

Pride Royal Ivy is an eight-year-old princess. One day she realizes something: in her previous life she had been an ordinary girl born into a typical Japanese family—nothing special, just a normal child. But now, she has been reborn as the cruel and merciless final-boss queen in the otome game Kimi to Hitosuji no Hikari o (“A Ray of Light With You”). Realizing this, she now decides to rely on her memories of having played the game and achieve something only she can do: avoid the coming tragedies and create a world where every character can find happiness. Thus begins a fantasy about a highly capable villainess princess striving to avoid becoming the final boss.
