"Routes" are the paths of the main story of this series. Yes, they have different endings, like you said. There are two known routes: Route 01 and Route XX. The anime might be different, so I don't know.

Starting with the easier one, Route XX is when our protagonist, Shintaro, never leaves his room due to his depression. Ene tried repeatedly to persuade him to go out, but he got tired of it and killed her though unknown means. Meanwhile, Kuroha appears and kills everyone in the Dan.

The other route, Route 01, is the route you're seeing in the anime. Shintaro finally gets out of the house when he spilled soda on his computer. He gets involved in a terrorist act and is rescued by the Dan, later to be forced to join. Following the novel, Ene sees Konoha with Hibiya on the streets and Shintaro runs after them for her sake. At the hospital where the former two goes, Hibiya runs away from Konoha and is caught by the Dan. The next day, while Momo is with Hibiya somewhere, Seto at work and Kano and Ene somewhere else, the rest of the Dan goes to Marry's house to find her mother's diary, the blue book you see in the anime.

This part is based on my own assumptions and some of the wiki's, too. When the Dan assembles together at night, Kuroha appears and is about to kill the Dan when something happens and he goes to kill himself. Shintaro interfiers and dies, entering the Heat Haze. There, he meets Ayano, who's been there forever, two years to be exact, who gives him her power. What happens after that is pretty obscure, but somehow the Dan manages to get to Summertime Record.
