''Every girl looks forward to her special day: Bat-mitzvah, Quinceanera or Sweet Sixteen. Reiha was no different with her Kascuza coming of age ceremony. It's almost a shame that the spirits started going crazy. That is exactly where you, the player, come in to Summon Night Twin Age for the Nintendo DS. Reiha and her brother Aldo must work with their Kascuza friends and a few humans (much to the loathing of Kascuza youth Nassau) to figure out what's going on with the spirits. Reiha and Aldo are not your average youth. Both teens were raised in secret by a Kascuza elder on a small island called Jarazi and were taught to respect the spirits around them, rather than forcing them to work like most humans. Guess which way of life the kids prefer.''
