Legend says at the end of the rainbow, there's a pot of gold. But the truth is, it's something even more amazing. Only a chosen few with an eye for bold fashions can follow the rainbow to Rainbow High, the colorful fashion school where everyone learns to flaunt their true color.

This original animated anthology follows three of the fiercest warriors in human history: a Viking raider guiding her young son on a bloody quest for revenge, a ninja in feudal Japan who turns against his Samurai brother in a brutal battle for succession, and a WWII pilot who takes to the sky to investigate an otherworldly threat to the Allied cause.

自古妖魔侵入人类的世界，化作人形并以吞食人类的内脏为生，对妖魔束手无策的人类唯有求助于身背巨剑的女性战士们。因为战士们是由于体内混合了妖魔的血肉才得到超人的力量，所以人类同样将她们视为异类，一方面依靠着她们斩杀妖魔，一方面畏惧并排斥着她们，并将她们称为“Claymore（大剑）”。 当妖魔的出现打破了一个普通山村的平静生活，万般无奈的村长只好求助于大剑组织。一位面容冷酷的战士接受委托来到这里，由此拉开了这场波澜壮阔的故事序幕。
