This in fact all took place in the school term previous to Little Busters!, and Riki and Rin are reliving it in an artificial world created by Kyousuke. They, and the other main characters, were involved in a bus accident during a school excursion, and only the two of them will survive. Kyousuke created the artificial world to make them strong enough to be able to deal with what will happen when they awaken in the real world. In the true ending, Riki and Rin are able to travel back in time, and save everyone at the scene of the crash.
同样是创造奇迹，KANON TV为什么偏要把阿由弄残，然后再后宫大游行，什么是奇迹，奇迹不就是即使是Time leap也不要考虑改变未来的合理性与否吗？
原作AIR的往人变乌鸦，小满化羽毛，KANON的三无少女自残后复原，狐狸变人等，甚至CLANNAD，既然存在奇迹，搞个毛产生了奇迹还外带残废。京都为了拖戏，也不要把剧情在后面几集这样地崩啊！
In the true ending, Riki and Rin are able to travel back in time, and save everyone at the scene of the crash.
京都啊，你Clannad敢不按以上方针搞，就代表小镜唾骂你……
