Lumines Electronic Symphony developer Q Entertainment has announced that it's bringing its free-to-play RPG Guardian Hearts Online to Japanese PlayStation Vitas this month. The title – which is currently only available for mobile platforms – is “a sprite-based, command-driven RPG where you hire other players as your NPCs”.

According to Famitsu magazine, the Vita version will boast an item transaction system, and will be free to download and play. A Japanese release is planned for later this month – but don’t expect it to make its way overseas any time soon.
