Allison to Lillia, Senjou no Valkyria Recommendations
Both have similar story and characters. they main characters want to stop the war between two sides. The feeling you egt from Valkyria Chronicles is similar to Allison and Lillia. Both very good anime (well Valkyria is good so far)
War between two countrys in WW1 sitting..
and the charecters has the same feeling in both anime.
The theme/setting is somewhat similar about the past, war, and whatnot. They both have romance, drama, and action. Art style kinda resembles each other, too, in a way. They, also, are very nice anime. :)
-Both are in the 1930's universe.
-Both are military/romance that is just likable
-Any many more things that I do not wish to think about ^^
Valkyria Chronicles felt like a bit more mature version of Allison & Lillia. If you liked A&L you'll probably enjoy Valkyria. Both of them involve military elements with Valkyria going a bit more in depth. Both of these shows also have very good romantic developments. Both are definitely worth watching!
