@Faun,i suggest dropping Kimi no Iru Machi simply because it will never be fully adapted to anime because of its size(252 chapters & ongoing).manga(at least upto around ch165 is very good).also the 2ep OVA does not start from the beginning of the manga.i suggest suzuka series from the same author which at least adapted into anime with half of the manga(starting 9 volumes out of total 18).
Watched 1st episode of Suzuka. Missing the art style, narration and seamless transitions. Kimi no Iru Machi looks more emotionally appealing.
Any other anime which you think has same variables ?
