Sword Art Online Alternative Gun Gale Online Novel Vol. 4 (novel)

Old frenemies become staunch allies as the strongest team in the history of Gun Gale is born! This time, LPFM, named for Llenn, Pitohui, Fukaziroh, and M, will enter the third Squad Jam and overcome fierce competition as they aim for the top! But with a map that's slowly sinking into the sea, an UNKNOWN area at its center, and a "special rule" that won't come into effect until the competition nears its end, this Squad Jam certainly seems shrouded in mystery...
