Manga Focus Lines in Clip Studio Paint: The One Thing to Get Right
Focus lines are one of those things that look like decoration and aren't. They're a pointing device. A panel can contain six things, and the lines decide which one you look at first — before you've consciously chosen anything.
They do a second job too. Lines radiating out of a panel raise its temperature. Tension, a blast, an impact, the moment somebody's voice goes through the roof. Same drawing, no lines: a guy shouting. Same drawing with lines: a guy shouting at you.
Here's the tool I use for almost all of them, and the one rule I'd give anyone starting out.
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.
On Paper This Is Hard. On Screen It Isn't.
I want to be straight about this, because a lot of tutorials aren't. Drawing focus lines by hand is real work. Consistent spacing, clean taper, every line actually aimed at the same point — that's a skill, and it takes a while to get.
Digitally it is not a skill. It's a tool. You don't need experience, you don't need a steady hand, and you'll get a usable result on your first try. That's not me being modest about a technique I've mastered; the software genuinely does the hard part.
Which means the interesting question isn't how do I draw these. It's where do I aim them. More on that below.
The Sub Tool I Use: Scattered Saturated Line
Clip Studio calls focus lines saturated lines, and they live inside the Figure tool. Select Saturated line and the sub tool palette fills up with variants.
Figure → Saturated line → Scattered saturated line
Ships with Clip Studio Paint. Nothing to download, nothing to buy.
Other sub tools in the same group: Dark saturated line, Dense saturated line, Brightness, Burst, plus a couple of tone-based ones.
I use Scattered saturated line for nearly everything. The name is literal — the lines bunch up in places and thin out in others instead of sitting at perfect intervals, which is what stops them reading as a machine-made starburst. That one sub tool covers the large majority of focus lines a manga actually needs.
To draw: drag outward from the centre. That's it.
There Is No Correct Setting
Open the Tool Property palette and you can adjust a lot: line width, thickness, length, how much gap sits between them, how they taper. It's tempting to hunt for the numbers a professional uses.
There aren't any. I'm not withholding them — they don't exist. The right values depend on your panel size, your line weight, your resolution, and honestly on your taste.
The only way to find yours is boring and unavoidable: use them, print or export the page, and read your own manga as a reader. Not zoomed in at 400% checking whether the tapers are pretty. Reading it. You'll know within a page or two whether a set of lines is doing its job or just making noise.
The One Rule: Set the Center Point First
Here's the part I'd actually defend as a rule.
Before anything else, put the center of the focus lines exactly on the thing you want the reader to look at.
Not the middle of the panel. Not the middle of the character. The specific spot — an eye, an open mouth, the point of impact, the hand holding the thing that matters. In the image at the top of this post the center sits inside the mouth, because the panel is about a shout.
Get that right and the rest stops mattering much. Lines too thick, too thin, too long, too short — it'll still look pretty good, because the geometry is already pulling the eye to the correct place. Get it wrong and no amount of tuning saves it. You'll have beautifully rendered lines pointing at somebody's forehead while the important thing sits off to the side, ignored.
The reason it works is simple. Focus lines are a giant arrow made of a hundred smaller arrows. If the arrow points at the wrong thing, how nicely it's drawn is irrelevant.
Watch It Happen
Ten seconds. Tool, then center point, then done:

That panel is from Episode 23, TRIAL, page 9. The face is Soujun's. Abura's pipe is already coming down and Yu-ri hasn't seen it — Soujun is the only one who has, and from where he's standing all he can do is shout a warning.
Which is exactly why the center sits inside the mouth. For that half-second the shout is the panel. Not Soujun's eyes, not the background, not the swing itself. The lines are there to make sure the reader's attention lands on the sound, because the sound is the only thing that can still change what happens next.
Look at where the lines are aimed on that page, then at the panels around it. Each set points somewhere different, because each panel is asking you to look at something different.

Soujun is sixteen, and he lives by one rule: never take a risk. He and his little sister can't afford one.
Then, for her sake, he takes exactly one. A single delivery, off the books, no questions asked.
That one risk turns him into a monster — a Fuser — and drops him, without his ever choosing it, into a world made of nothing but risk: the TOKYO underground.
DURRUN is a neo-TOKYO underground shonen manga. Every episode is free to read in English, right here.
And hey — go read DURRUN. Por favoooor 🙏
