Sword Art Online Alternative Gun Gale Online, Vol. 13 (Light Novel)

It´s the fifth squad jam and Llen´s valued at one hundred million credits. Thrown out into the fog, she´s persisted in looking for other participants and finally managed to team up with someone. However, one hour after the start, the outside field starts to crumble until all that´s left is a three-kilometer castle. Llen and friends just barely escape the crumble but Pitohui (?) dies from Shirley´s(?) exploding ball. The end is nearing, but there´s a newly added special rule.??
