While GungHo Online Entertainment is best known for Puzzle & Dragons, they also have a game that melds character flinging from Angry Birds with RPG gameplay. Usually you would flick warriors in Princess Punt, but a crossover event is adding Hatsune Miku as a cameo character.
When Hatsune Miku lands she can attack enemies in range by singing. Kagami Rin and Len are in the game too and can attack a group of enemies with Twin Harmony. Megurine Luka, Meiko V3, and Kaito V3 are also guest characters. Too bad the Titans from Attack on Titan aren’t in the game anymore. A Vocaloid vs. Titan fight would have been a sight to see.
Princess Punt is available for iOS and Android.
