Manga Speed Lines in One Stroke, Without Covering Your Art

Tone speed lines placed behind flying rubble without covering the line art, drawn in Clip Studio Paint for DURRUN by Aito Kitazaki
A demo made for the clip — speed lines added behind the rubble to show the tool working

Speed lines are how manga shows movement. Parallel lines running in the direction of the motion. Take them away and a punch is just an arm stopped in mid-air.

The problem is that speed lines are lines. Add lines on top of a drawing and the drawing goes away. The face you spent an hour on starts disappearing under the marks you added to make it feel fast.

This tool solves that. It lets you lay speed lines down as a tone instead.

MANGA TOOLKIT is a series about the tools I actually use to draw DURRUN — brushes, materials, auto actions, workflow habits. Written for indie manga creators drawing their own pages, with no studio and no assistants.

Tone Instead of Ink

A normal speed line brush draws black lines. Put them over your art and they fight it. Whatever was underneath is now partly gone.

This tool draws the lines as a tone, so the art keeps showing through. You get the speed without losing the drawing. Line art stays line art, with movement sitting over it instead of on top of it.

Which means you can do the thing that is normally a trade-off: an action panel where the character's face still reads clearly, and the panel still moves.


The Sub Tool I Use

CLIP STUDIO ASSETS Content ID: 2005591
Free · Material set · CLIP STUDIO PAINT PRO/EX

In the clip I am using the sub tool 2色流線D.

View it on CLIP STUDIO ASSETS →

The set is named for focus lines, but that undersells it badly. It holds nearly forty sub tools — focus lines, flashes, radial bursts, halos, and four speed line variants. The speed lines are the part I reach for.

It is free. For this much, that is a little absurd.

To use it, just draw the shape you want. Straight, curved, bent in the middle — the lines follow the stroke.

No affiliation, no sponsorship, no affiliate link. I use it, that is the whole relationship.

You Can Change It Afterwards

Length and thickness are adjustable in the tool settings, so the same tool covers a fast little panel and a full-page impact without swapping to something else.

The material page also documents a couple of edits I have not needed myself but that are worth knowing about: you can resize the whole thing with the Object tool, thin the lines out by touching near the middle of them, and add more by touching the empty space between them.

See It in an Actual Manga

One thing to be straight about: the rubble panel in that clip was set up for the reel. The published page does not have speed lines there.

But the same page does use them, somewhere better. It is page 4 of Episode 25, INSTANT — the close-up of Yu-ri's eye, and the tone sitting just to the right of it.

Here is the moment. Abura has launched a stone at him, and in the instant before it lands Yu-ri notices something: a faint haze around the rubble, and the way its path bent wrong. He is starting to connect two things at once.

What the reader has to see is his eye. That is where the realisation lives. So nothing can go over his face.

But the speed of the thought still has to land. So the lines go in as tone, off to the side, clear of him. Not speed, not impact — a thought moving faster than the stone.

That is the case this tool exists for. In ink you get two options: cover the face, or drop the effect. In tone you get to keep both.
