Summary:

That girl sacrificed her life with a smile. Joining them on their journey to defeat the Demon King was a helpless young magician. She had a cute smile, loved bread, and was happy to be of service to everyone. But her magic...was unleashed in exchange for her lifespan. Without telling anyone, without anyone noticing. She simply smiled and said, "I'm glad I was able to help," and disappeared at the end of their journey. Leaving behind nothing, not even a name or a past... Her companions still don't know. What was the burden of this girl, known as "Wizard-chan"? This is the story of a girl who saved everyone without accepting anyone's love, who disappeared after saving them all. However, in reality, the missing "Wizard-chan" was a member of a long-lived species that could live for tens of thousands of years. So it wouldn't have been a problem if she had used up a little of her lifespan... But now that she's gone, no one can explain that. And, for some reason, their adventure has ended up being aired as an anime in real life on Earth as a "Story of a World Enveloped in Kindness." It's a Misunderstanding + Clouding + Bulletin Board Message format. The clouding affects the characters other than "Wizard-chan" and the anime viewers who were excitedly watching it thinking it was a normal slice-of-life anime. The moment it's discovered that her lifespans have been consumed, hell begins. Everyone hope it has a happy ending.
