Log Horizon, Vol. 7 (light novel‪)‬

Shiroe left Akiba in search of 8,000,000,000,000 gold coins, setting off for the vast north lands. But, what he found there was a warning of a large scale raid about to occur.
In Akiba's unstable situation, Shiroe's chosen raid members include the galactic idol Tetora, the leader of Silver Sword who refused to take part in the round table council, Massachusetts, and the man he defeated in Susukino who still hates him, Demiquas.
...Is everything really going to be alright?
