🔥 KEY MOMENTS

⚠️ Spoiler Alert!

One by one, Kenichi and his family succumb to overwhelming drowsiness after eating the dumplings, slipping into a deep, unnatural hibernation right inside their own home.

Hattori arrives to find the entire household unconscious and quickly pieces together that Kemumaki is behind the scheme, recognizing the telltale signs of a ninja sleep technique embedded in the food.

4

Ninja Counter-Technique

Hattori unleashes his own ninja skill to reverse the hibernation effect, snapping the Mitsuba family back to consciousness and foiling Kemumaki's plan before any lasting damage is done.

5

Kemumaki's Comeuppance

With the family fully awake and the plot exposed, Hattori confronts Kemumaki directly — ensuring the rival ninja's mischief backfires on him in classic Hattori-kun fashion.

📍 ARC CONTEXT

This episode continues a loose thematic thread of sleep-related ninja antics, following the previous installment where Hattori experimented with sleeping techniques across various locations. The comedic rivalry between Hattori and Kemumaki remains the driving engine, with Kemumaki's schemes growing more inventive. It leads into the next episode, which humorously tests Hattori's supposed invincibility through challenges from his own friends.
