Kingdom Hearts 358/2 Days was released in Europe yesterday. This is the fifth title in the series, created for the Nintendo DS, set primarily between Chain of Memories and Kingdom Hearts II (but starts about 3/4 of the way through the first Kingdom Hearts), revolving around Roxas' time in Organization XIII and his motives for ultimately leaving the Organization to pursue the answers he seeks to questions about his existence.
