Clannad After Story Episode 21 English Subbed Episode Title:The End of the World.Episode Description: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 like last time, but he tells her that it will happen once she gets better. After Tomoya resigns from his job, 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 asks 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 dies calm and serene in Tomoya's arms right after telling her father that she loves him. Soon after, Tomoya collapses in grief and supposedly dies of shock, then something strange happens.
