Manga UP! Global has quietly expanded its catalogue with two notable additions: Chisato Nesumi’s manga adaptation of Kanae’s light novel with the long title The Baron’s Daughter’s Childish Transformation: An Envious Princess’s Curse and the Platinum Knight’s Proposal?! (Hime-sama no Shitto de Yōjo ni Sareta Danshaku Reijō Desu.), and Chūya Kogino’s manga version of Kazuma Kamachi’s long-running A Certain Magical Index. Both entries bring fresh entry points for readers who enjoy light-novel adaptations, character-driven romance and fantasy, and action-heavy urban fantasy respectively.

New on Manga UP! Global: What’s Landing
These two additions represent different corners of modern light-novel adaptation trends. Nesumi’s adaptation leans into romantic fantasy with a transformation curse twist and strong emotional beats, while Kogino’s A Certain Magical Index adapts a long-established action/fantasy franchise known for its sprawling cast and supernatural conflicts. For readers browsing Manga UP! Global, these are both high-value additions: one a newer isekai-adjacent romance, the other a classic franchise entry that helped define the 2000s light-novel boom.
Spotlight: The Baron’s Daughter’s Childish Transformation
Synopsis: Berna, a maid in the castle, is close to Dietrich — a handsome guard assigned to the prince — and intends to make his engagement ceremony run smoothly. When a princess rumored to wield dubious magic arrives, she casts a spell that forces Dietrich to make an unexpected proposal. To the shock of the attendees, Dietrich proposes to Berna — and in a jealous fury, the princess curses Berna, shrinking her body into that of a little girl. From there, the story unfolds as a romantic-fantasy slice exploring identity, agency, and the emotional fallout of public scandal.
Origins and Publication
Kanae serialized the story on the Shōsetsuka ni Narō website from December 2022 to January 2023. Chisato Nesumi launched the manga adaptation on Square Enix’s Manga UP! in May 2024, and Square Enix shipped the first compiled volume in May 2025. Nesumi’s prior work — including The Wizard and His Fairy, which she launched in 2012 and later saw English release through Kodansha USA in 2018 — gives readers an accessible touchpoint for her art and pacing style.
Why This One Sticks
The series taps into several hooks that draw readers: the age-transformation trope (which raises intriguing character and ethical questions), courtly intrigue, and the slow-burn romance between an ostensibly “common” character and an idealized knight. Nesumi’s art tends to emphasize expressive character faces and delicate paneling, which suits the story’s emotional swings and the contrast between the castle’s social formalities and Berna’s sudden vulnerability.
Spotlight: A Certain Magical Index (Manga Adaptation)
Synopsis: A Certain Magical Index centers on Touma Kamijou, an ordinary student living in Academy City whose one “power” is an extraordinary run of bad luck — and an even more extraordinary ability to negate supernatural phenomena with his right hand. When he meets Index, a mysterious girl who carries an enormous amount of forbidden knowledge, Touma’s life collides with the worlds of science and magic, and chaos inevitably follows.
Publication Background
Chūya Kogino launched the A Certain Magical Index manga in Square Enix’s Monthly Shonen Gangan in April 2007. The series has been collected into multiple volumes over the years — the reference material notes a 32nd compiled volume release — and Yen Press licensed the manga for English-language release in October 2014. The broader Index franchise began as Kazuma Kamachi’s light novel series in April 2004, with illustrations by Kiyotaka Haimura, and it later expanded into New Testament and Genesis Testament arcs. The franchise has inspired multiple anime seasons, a feature film, and several manga spinoffs such as A Certain Scientific Railgun and A Certain Scientific Accelerator.
Why New Readers Should Try Index
Index remains compelling because of its wide-ranging worldbuilding: an urban-science setting (Academy City) full of esper research and a parallel magical society with grimoires and sorcery. The contrast between cutting-edge science and ancient rituals makes for unique conflicts, and Touma’s character — a protagonist defined by tenacity and moral clarity rather than flashy powers — gives the story its human core. Kogino’s adaptation aims to balance the original novels’ dense plot threads with the faster pacing expected from a serialized manga.
Where to Read and What to Expect
Manga UP! Global is the platform hosting these adaptations, giving both series a global reach outside of print volumes. For readers who want to compare the manga to the original web novel, Kanae’s serialization remains available on Shōsetsuka ni Narō. You can read the original web serialization here: Shōsetsuka ni Narō — original serial. Expect clean digital reading, periodic chapter updates, and eventual physical volume releases for series that gain traction.
Author and Artist Profiles
Chisato Nesumi — Best known for titles like The Wizard and His Fairy — brings a polished, character-forward art style suited to romantic fantasy. Her background with serialized magazine work (including a Kodansha-published title) makes her a reliable adapter for emotionally complex material.
Chūya Kogino — Entrusted with adapting a sprawling franchise like Index, Kogino’s work has to balance high-concept action sequences and dense exposition without losing momentum. Fans of the franchise will watch for how the manga handles pacing and visually represents esper abilities and magic.
How These Additions Shape Manga UP! Global’s Lineup
Adding both a contemporary romantic-fantasy adaptation and a major action-fantasy franchise strengthens Manga UP! Global’s appeal across audience segments. New readers seeking sweet, character-driven romances can discover Nesumi’s work, while long-time light novel and anime fans will appreciate the accessibility of another Index adaptation in a global digital catalog.
Final thoughts
Both additions to Manga UP! Global offer clear reasons to check them out: The Baron’s Daughter’s Childish Transformation provides an emotional, trope-savvy romance anchored by transformation drama and courtly intrigue, while A Certain Magical Index brings a beloved franchise back into digital reach for new audiences. Whether you come for the heartbreak and healing in a cursed romance or for the high-stakes battles between science and sorcery, these manga make for compelling reads that highlight why light-novel adaptations remain a vital part of modern manga publishing.
