At the earlier episodes of little buster. he said that he has an illness called Narcolepsy. Actually, from the beginning of the little buster series, he already in
Kyousuke's world where all of his friends died on car accident
So we ca assume that Riki only had his illness, when he got into
Kyousuke's World
But what happen with the Narcolepsy that Riki had before he enters
Kyousuke's World ?
Did he still got this illness ?
