Clannad: After Story

Synopsis

Ushio has the same illness as Nagisa's and Tomoya decides to stay home to take care of her. In case he had to leave home, he calls for both Akio and Sanae to take his place. Ushio asks Tomoya that she wants to go on a trip again like last time, but he declines and tells her that it will happen once she gets better. After Tomoya resigns from his work, Yusuke wishes him the best of luck. Akio offers Tomoya some money, but he declines his kindness and Akio states that every man has something to protect. Tomoya believes that Nagisa's and Ushio's lives are somehow linked to the "changing" in the city. After several months, winter arrives and then Christmas. Ushio's fever still does not back down, and Tomoya seems to be getting sick as well and hallucinates the illusionary world. Ushio once again ask Tomoya to go on a trip, and he ultimately accepts thinking that he might not be able to fulfill another promised wish. After they leave the house and it starts snowing (remembering Nagisa's death), Ushio's fever worsens, and she dies in Tomoya's arms right after telling her father that she loves him. Soon after, Tomoya collapses in grief, then something strange happens. (Source: Wikipedia)
