ah it probably does. what is the quick mask feature? its different then creating a regular mask? given ive been drawing digitally for awhile now there are a lot of tools i should probably learn how to use more effectively, but usually if i don't know what something is i just avoid using it haha. ill look at it later when I get a chance and see if I can use it to quickly make censored versions of some of my other drawings, bit of a pain but at least pixiv said my censoring of the twinkle girl drawing was fine and I could unprivate it again.

Commission artist Mai-sensei (maisart.bsky.social as well as https://www.patreon.com/Mai_Arts) was going through a rough financial patch recently, so I reached out with an offer: The canon scene of a flirty Takeru and a flustered Sui in the classroom where they met!

Her commission sheet asks that customers not request "disturbing" content, so I checked with her first on whether she was okay with drawing this SFW scene of an otherwise extreme series, as well as whether she was comfortable having her name attached to it when I shared it. As you can probably tell from this post, both were fine.

So have some wholesome Takeru x Sui!

I am so sorry, I completely forgot to answer this. Looks like CSP does indeed have a Quick Mask feature. The bottom of this page describes how to use it:

Adorable Takeru x Sui.

I hope it helps Mai_Arts relax some.

this is amazing! they both look so cute here! Love the way Takeru looks in that suit too!
