[SUB] The Familiar of Zero (2006)

Eléonore drags Louise, Saito, and Siesta back to the Vallière house, where Louise is announced to be engaged to a duke. Saito goes to talk to her at night but instead finds her sister who beats him like Louise does. Saito confesses his true feelings to Louise, makes out with her in a childhood boat, fights his way out of the Vallière residence, and heads back to school with Louise. She doesn't believe him about what happened in an earlier incident and beats him again while Siesta tells herself she is the only one for Saito.
