Comiket 108 Fan-Made Physics Doujinshi "Let Hiro Shinonome Explain Physics" Is Absolutely Massive – Netizens Joke: "Hiro Would Break Her Bones Carrying That!"

Japan's largest fan convention, "Comic Market" (Comiket, C108), kicked off on August 15th and 16th at Tokyo Big Sight, drawing over a hundred thousand attendees on its first day alone, proving its insane popularity.

Among the myriad booths, one particularly intriguing fan circle, "500mL," has been making waves with their ultra-hardcore physics doujinshi starring Hiro Shinonome from "THE IDOLM@STER Gakuen Idolmaster." Titled "Let Hiro Shinonome Explain Physics," the book's unique concept and sheer physical heft have become a hot topic.

This isn't the first rodeo for "Let Hiro Shinonome Explain Physics"; this C108 marks the debut of its third volume. Far from your typical flimsy fan book, this doujinshi leverages Hiro Shinonome's genius persona to deliver a comprehensive, textbook-level explanation of physics theories. It's a legitimate reference book, packed with academic and scientific layouts. Measuring B5 size and boasting a whopping 620 pages, it's an absolute steal at just 2,200 yen for a fan publication!

Despite being the third installment, creator "500mL" shared that the first volume was actually the most challenging to produce. They assured potential buyers that the third volume is now accessible enough for high school students and general readers.


Just look at this thing! The content is presented in a conversational style, with Hiro Shinonome guiding you through the mysteries of physics. Folks, the pursuit of knowledge truly never ends!


For the launch of the third volume, the official account thoughtfully advised attendees on X (formerly Twitter) that the book is quite thick and to bring a larger bag to avoid struggling with it at the venue.

Netizens playfully quipped that Hiro Shinonome, with her slender frame, would probably break her bones trying to carry such a massive tome. Others joked that the book's thickness made it perfect for a "physical" lesson—perhaps a gentle tap to the head would help absorb the concepts faster!

One commenter even noted that it was comparable to their own university-level quantum mechanics textbook, truly cementing its status as a serious academic resource.

The sheer volume of the printed copies was astounding, with the creator "500mL" estimating the weight at around two tons. Is this truly the scale of a fan-made publication?

And get this: by noon on the second day, all two tons of stock had completely sold out! LOL!

Comiket truly has it all! The convention isn't just for anime and game creations; it's also a vibrant hub for showcasing personal passions in countless forms. If you're looking to unearth unique treasures and see how creators express their love, Comiket is definitely the place to be!
