Charon Siphon

High school student Nanatsu Io is left devastated after a crushing romantic disappointment. Seeking an escape from her heartbreak, she unexpectedly finds herself drawn into a peculiar establishment known as Cafe Acheron. There, she is greeted by Kiba and Resato, two strikingly handsome male employees who introduce her to the cafe's unusual atmosphere. Determined to transform herself and move past her pain, Io resolves to take on a new role and begins working at the mysterious venue as a waitress. However, securing this position requires more than simply filling out an application. To officially join the staff, Io must enter into a binding contract with the cafe's owner, Kiba. This agreement comes with a deeply strange condition: she is required to keep her st￭ bear companion by her side at all times. The situation grows even more surreal when the once-inanimate toy suddenly awakens, gaining consciousness and insisting on being addressed as "Father." Bound by her pact and thrust into an extraordinary world, Io must navigate her demanding new job while managing the bizarre reality of her newly sentient companion.
