Screentone (スクリーントーン)
Pre-printed patterned sheets applied to manga pages to create shading, texture, and gray values in a black-and-white medium. Traditional screentone is adhesive film cut and burnished onto inked pages; digital screentone replicates this as a layer in software like Clip Studio Paint. Dot density and line density are measured in LPI (lines per inch). Screentone is one of manga's most distinctive visual elements.
Seinen (青年)
Manga demographic targeting adult men, approximately ages 18–40. Seinen manga often features more mature themes, complex narratives, moral ambiguity, and realistic violence compared to shōnen. Famous seinen titles include Berserk, Vinland Saga, Vagabond, Monster, Punpun, and Tokyo Ghoul. The word seinen means "young man" or "youth."
Sensei (先生)
A title meaning "teacher" or "master" — used to address mangaka (manga artists), doctors, lawyers, and teachers. Fan communities often address their favorite mangaka as "sensei" as a sign of respect. In manga dialogue, the term signals a teaching or authority relationship between characters.
Serialization
The process of publishing a manga story in installments — weekly, bi-weekly, or monthly — in an anthology magazine before collecting chapters into volumes.

The Weekly Shonen Jump reader ranking survey determines which series get continued serialization and which face cancellation.

Key titles: Naruto, One Piece, Dragon Ball, My Hero Academia, Demon Slayer, Jujutsu Kaisen.
Splash Page

A double splash page spreads across two facing pages and is reserved for the most spectacular scenes in a chapter.
