A SeiSub Hanami gift for @celestialrand.bsky.social - AU. Teenaged Subaru is working as a mech pilot and onmyouji for the government. The Sakurazukamori is bored. Tasked with increasingly large-scale monsters, Subaru quickly finds himself in deep over his head. archiveofourown.org/works/82676656

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

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

This is an illustration of the characters Subaru Sumeragi and Seishirou Sakurazuka from the manga-anime Tokyo Babylon. However, their roles are reversed as they would have been in the original.

A portrait of Seishirou and Subaru from X/1999 standing in front of a grassy backdrop leading to a large body of water. Subaru looks out behind Seishirou toward the water and Seishirou takes Subaru by both of his hands, holding him a bit awkwardly as Subaru mildly resists. They're dressed in kimono, Subaru in red and Seishirou in white. A well-healed scar of teeth marks the side of Subaru's neck.
