Sumireko Usami is not a normal high-schooler at all. She is so abnormal that even the fantasy land of Gensokyo considers her an anomaly. Truth is, she can visit Gensokyo in her dreams!

Artificial Dream in Arcadia is a first person dungeon crawler where the player, as Sumireko, has to navigate tricky mazes and capture a party of the strongest Touhou characters to assist them in turn-based battles. Go all over Gensokyo and beyond, to solve an incident which seems a little too convenient for Sumireko, seeing as she's the only person in Gensokyo who has a tool to control this infestation of clones: her newly-bought smartphone.
