Imagine you are in a world where evil monsters called "spirals" wreck havok. Imagine you're part of a standard RPG adventurer party that takes quests for the guild and fights these monsters. Now imagine you all suck at it. That's Last Period in a nutshell. A party of dorks taking on another party of dorks while occasionally taking care to actually fight monsters and do something useful. Rarely. This is a show based on a moa, and a gacha one at that. Remember kids, don't do gacha. Not even once.
