Gift for Tomira, for the new 2025 edition of the @seisubhanamiex.bsky.social . #SeiSubHanamiExchange2025 #SeiSubHanamiExchange The prompt used concerned the Edo, Meiji and Reiwa eras. Edo: I focused on a fleeting encounter. The time of a cross between two onmyouji apprentices.

Gift for Tomira at the @seisubhanamiex.bsky.social . The theme of the prompt is "something about paranormal investigations". This is short sequence which I mixed with urbex in the background (as "paranormal" live performances have been tendance in recent years). 1/4 #SeiSubHanamiExchange

My entry to this year's #seisubhanami exchange!! This is for Kotorii with prompt: sexy hand/face grabbing in the tone of classic X illustrations. I went with more hanahaki direction with this one. Thanks for the challenge! @seisubhanamiex.bsky.social

An illust for the SeiSub Hanami Exchange 2025 project which was a lot of fun to participate in! I uploaded this to insta so I figured I'd also share it here. @seisubhanamiex.bsky.social

My gift for @iskendaris.bsky.social for the #seisubhanamiexchange2025! Title: In Trutina Mentis Dubia Words: 8,612 Summary: Arranged marriage AU. How can Subaru live a lie? And Seishirou just might care what Subaru thinks of him? archiveofourown.org/works/64612417 #seisub
