Nagi no Asukara
MAL score: 8.7!
So for Comedy/Drama/Romance with reasonable amount of each I would go with Nagi no Asukara. And honestly the scenery/backgrounds are simply gorgeous so you have plenty of visual aspects to look at as well. But unlike some anime they do not expect that to carry the film.
The series main focus in around two middle school friends. One of them is the indecisive crybaby Manaka Mukaido and Hikari Sakishima, who has looked after her since they were children.
Hikari and his friends' lives change when they are forced to deal with the deep-seated hatred and discrimination the people of sea have against the surface. By the end of the anime their personal lives, as well as an impending tempest which may spell doom for all who dwell on the surface comes fully alive.
If you've watched and liked Clannad, I highly recommend you check out Kanon which was released in 2006.
I personally strongly preferred it over Clannad's first season, though if you have watched Clannad: After Story I think that you will agree that it is much better than Kanon.
I found pretty much all of the other studio Key adaptations:
- Little Busters!
- Angel Beats
Ef – A Tale of Memories
Ef is really my favorite drama show – anime or other – of all time. The reason is simple, Ef – A Tale of Memories is an amazingly heartfelt story which brings forth lots of tears and the reuired happy moments to smooth them out.
The series also tells the story of Renji Asou which is a really heartwarming tale as well.
Before I skip out for today I would liketo suggest one more show. If you liked Ef, or want to watch it, you will probably like Rumbling Hearts since it is an incredibly well made drama.
It's not a tearjerking drama like Ef but it will leave you feeling depressed throughout the entire series. I personally like to think of it as the 'grandfather' of anime drama since that is pretty much all the show does (there is hardly any secondary genre to speak of).
