Light Novel Volume 15 is the 15th volume of the In Another World With My Smartphone light novel series written by Patora Fuyuhara with illustrations by Eiji Usatsuka.
After a series of troubling events, Mochizuki Touya takes some much-needed downtime. The fate of two worlds still hangs in the balance, he needs to secure more allies in the Reverse World, and Yula and the wicked god continue their dark machinations in the background, but that doesn't mean that our hero can't take a little time for romance and relaxation. But unbeknownst to our crew, another god may have set his eyes on the mortal realm... Lovers waltz and blades clash, unveiling a story of swords, sorcery, and fun in the sun!
