あらすじ
The second season of Tate no Yuusha no Nariagari. With another Wave happening in a week, Naofumi Iwatani and his party have no time to waste. However, when bat familiars raid Lurolona Village and the Wave countdown comes to a halt, the Four Cardinal Heroes reconvene with the queen, Mirelia Q Melromarc, for a quick briefing. The queen presumes that the odd occurrences are linked to the Spirit Tortoise—a threatening creature that has awakened from its slumber, back to cause havoc once again.
