It’s CLANNAD: After Story episode 1, the continuation of the CLANNAD series from last fall. This episode is largely meant to reintroduce the viewers to the primary characters involved.
This is the third and final omnibus that I’m putting together, this one of the middle six episodes of Someday’s Dreamers: Summer Skies, which span from episodes 5 through 10, which is as far Kissfan has gotten in subbing the series, even though I believe the series has finished airing in Japan.
