I Am Learning to be a Succubus?

Lili, once a diligent older brother, finds herself adjusting to a new life as a succubus with limited success. As her physical form becomes more feminine, she begins to lose her original identity and sense of self. Her new big sister advises that the only way for Lili to regain her former abilities is to feed as a succubus, a prospect that fills Lili with uncertainty. With little choice in the matter, Lili decides to give this new path a try. To compensate for her lack of academic progress, Lili attends a cram school during her summer break. However, her grades show little improvement, despite the assistance of her class's top student, Daisuki. Standard studying techniques seem ineffective, and Lili wonders if a more unconventional approach might be necessary to grasp the material. Perhaps, she thinks, a succubus's unique abilities could be the key to unlocking Daisuki's knowledge and understanding. Lili's situation becomes increasingly complicated as she navigates her dual identities as a succubus and a student. Her struggles to balance her academic and supernatural responsibilities create a sense of tension and uncertainty, leaving her to question whether she can truly find a place for herself in this new world.
