The main work is finally done for Silver Witch Princess Vai. Here's a preview of the first episode:

Title screen of Silver Witch Princess Vai

"There was much work to be done if Mauveine was to give Vai a comfortable, safe life here in this little harbor town. More than anything, she needed that. As much trouble as it might be, the girl deserved a quiet life."

Vai: I'm going to cast a spell. Don't distract me.

#makeaterriblecomicday2026 | #art | #OC | #V_UAL Taking this opportunity to say I'm taking a detour from YDSP to try and work on a smaller project this summer. All that magical girl research had to result in something, I guess

Since the itch.io statement specified that only free NSFW games are to be reindexed, it's possible that Yudashi Peril: Floraison won't be available unless I make it free. I'm not actually sure if they would even un-suspend it even in that case. I'll have to think on this. #YDSP

It appears that Yudashi Peril: Floraison's files have been suspended on itch.io, likely because I marked the game as NSFW as a safety precaution due to adult themes. This is a lesbian visual novel with no explicit sex scenes, and it has been the most important art project in my life. #YDSP
