Ep. 13: Tomoya proves his worth to Akio and celebrates Nagisa's graduation before their wedding.

13

Tomoya attempts to persuade Akio to approve his marriage to Nagisa, but Akio demands he demonstrate skill in baseball first. Tomoya practices relentlessly in heavy rain until he hits a home run, earning Akio's consent. Months later, during Christmas, Nagisa turns twenty and consumes sake for the first time. While intoxicated, she accuses Tomoya of feelings for Sanae, and her subsequent fever causes her to miss school without repeating a year. Tomoya organizes a graduation celebration with friends and former classmates, including Koumura, at the school. Nagisa receives her diploma and officially graduates. They inform Naoyuki, who offers congratulations. Shortly after, Tomoya and Nagisa marry while walking among cherry blossoms on a hill.
