A monk trying not to wake up while a entire temple's worth of girls sleepwalk around him is the kind of stupid-specific premise that either lands or dies in the first five minutes. Ikko stays conscious through sheer panic and desperation. The special knows exactly what it is and commits to the bit without apology, which is all this kind of comedy needs to work.
Ikko's luck takes a bizarre turn when he and the residents of Saienji Buddhist Temple win a vacation package to an isolated hot spring inn. What should be a peaceful retreat becomes chaos when the girls all fall into a synchronized sleepwalking state on the first night. Now Ikko faces an impossible mission: remain conscious while navigating a gauntlet of sleepwalking women in increasingly compromising situations. Every moment he stays awake brings him closer to victory, but exhaustion gnaws at him relentlessly, and the girls' unconscious movements grow progressively more problematic. The tension ratchets between his determination to succeed and the mounting temptation surrounding him at every corner. This special cranks up the absurdist comedy that defines the franchise, blending slapstick desperation with the supernatural chaos that makes the temple cast so unpredictable. Perfect for viewers who enjoy romantic comedies that don't take themselves seriously, where the humor comes from escalating awkwardness and characters pushing each other to ridiculous extremes.
