Mashin Creator Wataru [Season 1 Episode 15]

Episode 15 Review: Mashin Creator Wataru

A Wild Ride of Emotions and Twists

If you’ve been following Mashin Creator Wataru, you know it’s not your typical isekai adventure. Episode 15, titled “The Ultimate Prank War”, takes the chaos to a whole new level, blending humor, action, and some surprisingly deep character moments. As a fan of the series, I couldn’t help but dive into the online discussions to see what everyone else thought—and let me tell you, the reactions are as wild as the episode itself.

The Plot: A Prank Gone Too Far?

For those who need a quick recap, Mashin Creator Wataru follows 4th grader Wataru Hoshibe, an aspiring RyuTuber (yes, that’s a thing here), who gets whisked away to the parallel world of Chubukai. Alongside his robot partner, Ryujinmaru, he’s tasked with saving this bizarre world from destruction.

Episode 15 kicks off with Wataru and his cousin Kakeru (who’s also stuck in Chubukai) engaging in an all-out prank war. What starts as harmless fun—think whoopee cushions and fake spiders—quickly escalates when their pranks accidentally awaken an ancient Mashin (a powerful mecha-like entity) that’s been dormant for centuries. Suddenly, the duo has to clean up their mess before the entire world pays the price.

The episode balances slapstick comedy with high-stakes action, a combo that’s become a signature of the series. Fans on MyAnimeList pointed out how the writers managed to make even the silliest moments feel consequential—like when Wataru’s RyuTube livestream becomes the key to calming the rampaging Mashin.

Fan Reactions: Love It or Hate It?

Scrolling through discussions, I noticed a clear divide:

1. The Comedy Lovers

2. Many fans adored the episode’s over-the-top humor. One user wrote, “I haven’t laughed this hard since Wataru tried to explain memes to Ryujinmaru in Episode 3.” The prank war was a highlight, especially Kakeru’s increasingly ridiculous traps (one involved a giant inflatable duck—don’t ask).

3. The Critics

4. Some viewers felt the episode leaned too heavily into comedy at the expense of plot progression. A Reddit thread argued, “It’s fun, but I wish they’d focus more on the overarching mystery of Chubukai.”

5. The Mashin Fans

6. The introduction of the ancient Mashin was a big deal for lore enthusiasts. Its design—a mix of traditional Japanese aesthetics and futuristic tech—got a lot of praise. One Tumblr post even called it “the coolest mecha since Ryujinmaru’s debut.”

Standout Moments

• The Livestream Twist: Wataru’s desperate attempt to fix things by livestreaming the chaos was genius. It’s a nod to modern internet culture, and fans loved how it tied into his character growth.
• Kakeru’s Redemption: After being the “straight man” for most of the season, Kakeru finally lets loose, and it’s glorious. His dynamic with Wataru is becoming one of the show’s strongest points.
• The Mashin’s Awakening: The animation during this sequence was stunning, with vibrant colors and fluid movements that made the battle feel epic despite the silly setup.

Final Thoughts

Episode 15 of Mashin Creator Wataru is a rollercoaster—funny, action-packed, and surprisingly heartfelt. While it might not advance the main plot much, it’s a perfect example of why this series stands out: it embraces its absurdity while still delivering memorable moments.

If you’re looking for a show that doesn’t take itself too seriously but still knows how to keep you hooked, this episode (and the series as a whole) is a must-watch. And hey, if nothing else, you’ll never look at inflatable ducks the same way again.

Rating: 8.5/10 – A hilarious, chaotic ride with just enough depth to keep you coming back for more.
