With such a vast array of Kingdom Hearts characters arriving in this game, one can only hope that they make their way westward in due time.
All of the Kingdom Hearts characters that have been a part of Tsum Tsum so far are Aqua, Shadow, Xemnas, Ansem, Halloween Sora, Bolt-headed Goofy, Kairi, KH3 Sora, King Mickey, Mummy Donald, Riku and Sora.
Are you a LINE: Disney Tsum Tsum player? And if not, do these character inclusions entice you into giving the game a chance?
