About TV Anime "Though I Am an Inept Villainess: Tale of the Butterfly-Rat Body Swap in the Maiden Court"
The 雛宮 (Hinomiya) is a palace where maidens from five noble houses have gathered to be raised as future consorts. Reirin, the maiden of the esteemed Kō family — praised as "His Highness's Butterfly" and loved by all — has her body swapped with Keietsu of the Shu family, a maiden scorned as a villainess, on the night of the Tanabata festival.
When she regains her senses, she is told her execution has already been decided. Yet Reirin, who has lived close to death since childhood due to illness, instead rejoices at being in a healthy body.
What seemed like a tragedy becomes an opportunity: Reirin, with a spirit of steel, enjoys her freedom even after being banished to a ramshackle house, and charms with her innate brightness and kindness those who seek to take her life, overcoming obstacle after obstacle. Meanwhile, Keietsu, who had envied and despised Reirin, finds her heart beginning to waver as she encounters Reirin's true character.
Two young women whose souls swapped on a shooting-star night — from that day, their fates change dramatically, and they soon become entangled in a conspiracy that shakes the entire imperial court. A tale of two opposites staging a dazzling court body-swap reversal, now begins.
