Nakajima Handed the Project Over Completely
The announcement came with a commemorative illustration and a short note from Nakajima, published by Japanese entertainment news site Comic Natalie on September 25. Her comment on the production itself was hands-off. The anime staff she met had a firm grip on what the work was going for, she wrote, so she told them to make it however they liked and left the whole thing to them.
She also singled out two parts of the production that have yet to be shown. The character designs and the theme song are both finished, and she described both as wonderful.
She added one caveat. Some expressions have been changed or added in taking Eruru to a worldwide audience, Nakajima wrote, and she hopes readers enjoy the differences from the version serialized in the manga magazine Comic Cune. She does not say what changed.
One Problem, Stretched Across a Whole Series
Eruru Shikkoshī (エルル・シッコシー) is an elf who leaves an elf seminary in another world to do a teaching practicum at a human school. She can only relieve herself in a forest where grass and flowers are in bloom. That single condition is the engine for every gag in the book.
The premise rests on a pun. Japanese uses ohanatsumi, literally "flower picking," as a polite way to say a woman is stepping away to relieve herself, and Comic Natalie filed the first volume under exactly that description back in 2024. For Eruru, the flowers are not a euphemism.
The manga launched in Kadokawa's Comic Cune in January 2024 and also runs on KadoComi, Kadokawa's manga app. Volume 1 came out on July 26, 2024, with volume 2 following in February 2025. The series returned from a break on September 26, 2026, the day after the anime reveal.
This is Nakajima's second anime credit. Her earlier series Tenshi no Drop, listed in English databases as Angel's Drop, became a six-minute special from AIC Frontier that aired on AT-X in May 2013.
Wave's DeRegula Label Is Behind It
The copyright line reads © Chizuna Nakajima / KADOKAWA / Wave, and the announcement itself came from Wave Inc., the Tokyo company whose anime label DeRegula is producing. DeRegula launched in June 2023 with a stated focus on "stimulating" source material, built on Wave's long run of late-night shorts. Wave also operates the ComicFesta and AnimeFesta services.
The label's slate so far skews adult. Chuhai Lips: Canned Flavor of Married Women ran eight episodes across July and August 2025. Ingokudanchi, announced in January 2026 as DeRegula's fifth production, was retitled from its racier manga name for broadcast. Set against that lineup, a Comic Cune school comedy is the gentlest thing the label has picked up. Nakajima's line about changed and added expressions is the only clue to how far the anime will drift from the manga.
No studio, director, series composition, or voice cast has been named.
Looking Ahead
Everything concrete is still pending: broadcast window, staff, cast, and where anyone outside Japan will be able to watch. The anime has opened an official X account (@elfsensei_anime) for updates, and Nakajima's comment suggests character designs and the theme song are the likeliest next reveals.
International fans have no legal way in yet. The manga carries no English-language license, so Yen Press, Seven Seas, and Kodansha USA are all out of the picture for now, and the free first chapter on KadoComi is Japanese only. No streaming partner has been named for any territory. DeRegula's earlier titles have mostly stayed inside Japan's own services, which makes an international pickup something to watch for rather than assume.
