🔥 KEY MOMENTS

⚠️ Spoiler Alert!
1

Kemumaki's Bold Challenge

Kemumaki confronts Hattori directly, boasting that his modern ninja techniques are superior and demanding a formal duel to settle it once and for all.

2

Hattori's Mopping Mastery

Hattori pulls out his signature ninja mopping technique during the duel, turning an everyday skill into a surprisingly versatile combat move that catches Kemumaki off guard.

3

Modern vs. Traditional Clash

The duel escalates as Kemumaki deploys gadget-driven modern methods against Hattori's classical ninja arsenal, resulting in a rapid-fire exchange of tricks and counters that swings wildly between intense and hilarious.

4

Comedic Backfire

Kemumaki's overreliance on flashy modern techniques leads to a series of self-inflicted blunders, undercutting his bravado and giving Hattori the upper hand through sheer simplicity and adaptability.

5

Tradition Prevails

Hattori ultimately proves that classic ninja fundamentals outmatch Kemumaki's gimmicks, closing out the duel with a decisive and crowd-pleasing finish near the series' end.

📍 ARC CONTEXT

As episode 690 of 694, this is among the final handful of entries in the entire series, yet it operates as a self-contained comedic showcase rather than building toward a grand finale. It continues the long-running Hattori-versus-Kemumaki rivalry that has been a pillar of the show from the beginning, giving fans one of the last pure explorations of that dynamic. With so few episodes remaining, each standalone outing like this carries an unspoken weight for long-time viewers savoring the series' final stretch.
