In search for help in Identifying / Recreating a brush from CSP

As a beginner artist trying my first art program, I saw this brush that caught my eye the moment I found it. The problem I have is that it’s only available on CSP, and as I am a beginner artist, I don’t know a thing about trying to recreate brushes by myself or finding ones that are close to the one I’m looking for.

My partner tried helping me find one that looked close to it, but we failed in the attempt. Another wall that we were stuck on is that the information about the brush is in Japanese, so we couldn’t find a post regarding any recreation of it.

This is the only reference I have of the brush itself, but I managed to find the upload page by the original artist who created it. Sadly, as I do not have CSP, I can’t give any more references on how the brush works.

Link to the original upload of the brush:

I downloaded the brush in CSP and played around with it a bit; the brush that looks most like it is this one, but I tweaked it a little.

Here are my settings:

For the size, use one of the curve presets; I’ve marked it in the image:

Here’s a quick little test; everything is drawn with the modified brush:

Thank you so much for the help! I wouldn’t have been able to do this by myself. Sorry for making you spend your personal time finding a brush and tweaking it for me, I’m so grateful for your kindness!
