Touch, Cross Game Recommendations
So here we have yet another of Adachi's baseball mangas. You can found the same childhoodfriend setting, only this time we have two girls and one boy. Both of these concentrate mainly on baseball and getting to Koshien, but have a nice romance going on all the way through the series.
Both were written by same author and storywise I feel both mangas have similar settings, both Tatsuya and Kou at first didn't really like playing baseball but after one incident they felt they must really give their all to win the koushien.
Both mangas also have "Adachi's way" feeling in handling the romance.
So if you like reading Touch, pretty much you will also like reading Cross Game
These series are very similar. In both series the main protagonist takes on the dream of a deceased person with who both the male and female lead were very close to go to the Koshien. The main characters are also very much alike though Touch has more and slightly different supprting roles.
