Re:Zero and Touhou Project crossover. Natsuki Subaru, a young man forced to age much faster than any youth had any right to, finds himself suddenly stranded in a forest, far, far away from the Pleiades Watchtower and all his friends. Fujiwara no Mokou, an immortal and woefully bored recluse of seven centuries, finds herself roped into a conversation for the first time in... well, she never cared to keep track. (Takes place at the end of Re:Zero's arc six and during Mokou's 300 years of boredom before the main Touhou games). Cross posted to Ao3 and FFN. First time posting on Royal Road.
