Blade of Seafoam rkgk sketchlog 1 #bladeofseafoam
Pencil doodles of Axellion Aihara dressed in a kimono, a medium-length dress, and in athletic shorts with ripped black tights. Pen doodle of the XG-01 Bhairava mecha in semi-Super Deformed chibi proportions. Pen doodles of Shinjiro Yamashiro and Angelo Cabuyao in their military uniforms. Angelo's sleeves are tied together with a belt, and his feet are actually on spiky robotic heels. Rough pen doodle of a mech pilot inside of a cockpit.

Axellion's hair is actually dyed! Now you'll never be able to unsee it... #bladeofseafoam #axellionaihara
Two drawings of Axellion Aihara, one with his dyed blond hair (with brown-black roots) and one with his natural black hair with a slight brown shade. At the bottom, a chibi version of Axellion says "Don't I look cute either way?" and a chibi Toshiaki thinks "I honestly didn't even realize he wasn't a natural blond..."

Revised versions I ended up posting to Instagram -- keeping it to fictional characters only, and swapping in Tamamo because she's more of a personality inspiration for Axellion than Mem-cho is

Toshiaki and Axellion casual outfit notes
#bladeofseafoam
Artwork of Toshiaki Mizushima with some notes on his outfit. His back has a Coreframe piloting input dock, and the back plate can interface with his TYPE NEPTUNE nanomachines to create his pilot suit underneath this clothes in under 30 seconds. His shirt is a lightweight breathable jinbei. His pocket containers are on belts. His tactical armored boots are more comfortable than going barefoot. Artwork of Axellion Aihara with some tongue-in-cheek notes on his outfit. Everything in this outfit is chosen by Axellion to look both cute and vaguely tactical! His boots are legitimately pretty comfy to wear though.

Still incredible that Yoji Shinkawa makes physical clay sculptures of his mecha designs to make sure their weight is balanced, and funnily enough my fanart keychain of RAY (inspired by his inking style) can literally stand on its feet without any support
I will never be a doubter of Shinkawa

Have you seen that one piece of official CCA artwork that probably also inspired that incredible fanart?
Official Char's Counterattack artwork where the Nu Gundam faces away from the Sazabi, while half-naked Char and Amuro dramatically face away from each other in the middle.

It's spooky season, and that means I've drawn an updated version of my Duo Maxwell + Deathscythe Gundam chibis #gundamwing
Digital artwork of the Deathscythe Gundam and Duo Maxwell in chibi proportions. Duo is doing a two-fingered salute while smirking, and the Deathscythe is resting its scythe on its shoulder. The same artwork, but Duo's mouth is now open as if speaking, and the Deathscythe's eyes are glowing.

My current 2025-2026 convention schedule
I only have Michigan-based anime conventions booked right now, but I hope I'll have more 2026 conventions on my schedule soon!
Image with the Diurnal Days Art logo and the text "Convention Schedule: Youmacon, Detroit Michigan, October 31 to November 2nd. Isshocon, Ypsilanti Michigan, January 23rd to 25th. More conventions coming soon (hopefully)." There is a "Michigan Mentioned" meme in the corner
