When a manga adaptation goes wildly off-script, you expect an awkward statement from the original author. Not with Chi Fuyo, the Japanese fantasy series about an exiled mage who can enhance equipment.
Its novel creator, Asa Rokushima, put a remarkable warning on the original web novel’s page: the novel and manga differ by “99 tenths.” That's 990 percent if you insist on doing the math. The number is an obvious joke, not a scientific measurement of plot divergence. But the message is clear: don't expect two interchangeable versions of the same adventure. [1]
Same starting line, a different race
Both stories begin with Rain, an enchanter kicked out of his guild. He takes back the enhancement points he'd invested in everyone else's gear and puts his power to work for himself. From that shared premise, the manga by Gyomuyomochi develops a substantially different story.
Think of it this way: you show up with the novel as an answer key. The manga has changed the exam.
Then came the even better twist—not in the story, but in the creator comments.
The creator sounds like he's waiting for the next update
When the manga-based anime was announced in February 2026, Rokushima publicly said he enjoys reading the manga whenever a new installment appears. The manga artist, in turn, thanked the original author for allowing the serialization. [2]
Novel creator: “These versions are 990% different.”
Also the novel creator: “I look forward to every new manga chapter.”
Sir, you're the person who wrote the original story. Why does this sound like a fan checking for updates?
For clarity, that last line is a joke about the public comments. It doesn't tell us what either creator knew behind the scenes or what their agreement says.
And the novel hasn't quietly ended, either. On October 12, 2026, the web version was still listed as ongoing, with 249 episodes and a latest update dated October 8. [1]
That's the charm of this unusual adaptation: the novelist is still the novelist, yet somehow sounds completely at home in the front row of the manga's audience. Even the credits have comedic timing.
