Undefined Fantastic Object (東方星蓮船,Touhou Seirensen?, Eastern Star Lotus Ship) is a vertical-scrolling shooter and the twelfth official installment of the Touhou series.
At the beginning of spring, a strange flying ship appears in the skies of Gensoukyou. Based on rumors of it being a treasure ship, the protagonists set out to learn more about the ship and possibly plunder it in the process, all the while defeating youkai for the sake of Gensoukyou's fragile human-youkai balance.
In this game, three playable characters are available:
Reimu Hakurei, the Shrine Maiden of Paradise.
Marisa Kirisame, the Ordinary Magician.
Sanae Kochiya, the Newbie Goddess of the Mountain, returning from Mountain of Faith.
