Manta is a South Korean digital comics (or webtoons, webcomics, manhwa) platform owned and operated by RIDI Corporation.

Main titles of Ridibooks such as Under the Oak Tree (상수리 나무 아래) and Lady Devil (마귀) are also well known globally through Manta.

[8] RIDI Corporation initially established its presence in the industry as an e-book publisher, and over time, it expanded into other content domains, with a particular focus on webnovels.

The platform also works with third-party IP rights holders to extend existing films and live-action storytelling into webcomics, such as Svaha: the Sixth Finger[15] and A Hard Day.

[3] In Q3 2022, two volumes of Semantic Error were released as ebooks on Amazon Kindle, marking the series the first of Manta's titles to be published outside its platform.
