What this review measures, and what it doesn't
Dated releases: manga, manhwa, manhua and webtoon published in France.
Series: A series groups the volumes of one title, with volume numbers and edition mentions removed.
New series: A series whose first dated release falls within the period. Reissues, box sets and collector's editions excluded.
Publishers: Co-editions are split on the "/" separator. A publisher is active if it has at least one release.
Groups: A group is the sum of its imprints. The imprint → group mapping is curated by hand; an unmapped imprint stays counted under its own name.
The limit that matters: The dataset measures published output, never sales — no French publisher discloses them. This review therefore describes
supply — what publishers choose to publish — a leading indicator, but not revenue.
Two known flaws this quarter
Typing is incomplete. 38.4% of the quarter's
releases (331) have no type in the dataset. This is not a measurement error,
it's a lag: Manga-News records are filled in after release. Any share-by-type published
here is computed on the typed subset, never on the total, and it will shift at the next
recompute.
A namesake, found and fixed. While checking the three titles in the
picks above, Cosmos (Ki-oon, April 2026) carried in the dataset the type
"Sonyun-Manhwa", a Korean origin publisher and genres that weren't its own: they were the
metadata of another Cosmos, a manhwa published by Kana in 2006. The dataset types
new volumes by matching them on the title of an already-known series — a mechanism that
keeps the typing rate up, and that breaks on namesakes. Same family of flaw as
Wind Breaker, documented in the previous quarter.
The two volumes of Cosmos were retyped as Seinen, and the genres inherited from
the wrong series were cleared rather than replaced: when a value is wrong,
unknown beats false. The other two titles in the picks, which shipped with no type, were
filled in by hand: Shojo for Fall in love, False Angels (Pika Shôjo
imprint, serialised in Dessert), Yuri for Inkya Gal Revolution ! (serialised in Comic Yurihime). These five corrections are declared, sourced
and reproducible in scripts/types_manuels.json; they carry the
_type_source = manuel marker, which makes it possible to tell them apart
from automatically typed rows at any time.
