Digital artwork of V.IV Rusty (in his mech Steel Haze) from Armored Core VI: Fires of Rubicon standing in an action pose while surrounded by smoke and flames. His laser slicer weapon is open and actively spinning. In the background, a dust cloud forms the silhouette of Steel Haze Ortus, his future mech. Digital comic page from Blade of Seafoam. In the first panel, several mecha fly through the open air over the ocean while holding rifles. In the second panel, a more distinctive-looking mech banks to the side in mid-air to fly toward a waterfall that spills into the ocean. In the third panel, the distinctive-looking mech lands in the water at the edge of the waterfall, and shadowy silhouettes in the foreground turn to look at it. Digital artwork of Axellion Aihara (left, feminine-looking blond man with long hair) and Toshiaki Mizushima (right, masculine dark-skinned man with dark short undercut hair and stubble). Axellion is excitedly talking about something with his eyes closed, and Toshiaki is listening with his eyes closed and a slight smile on his face. Heart and sparkle symbols float around them, as well as a chibi Bhairava mech and the gay relationship symbol. The background is a purple and blue gradient with a black heart outline framing the two characters. Digital artwork of the YF-19 and YF-21 Variable Fighters from Macross Plus racing against each other through a blue sky over the desert. The contrails from their wings create dramatic arcs through the sky.

Blade of Seafoam extra short comic 2: Previous partners #bladeofseafoam #ocsky #occomic
Page 1 of a grayscale sketch comic in the Blade of Seafoam universe. Panel 1: Axellion lounges on his side. He has a plate of kelp snacks next to him. Axellion: "Toshi, did you have anyone else before me? Like, any other partners?" Panel 2: Toshiaki is looking out the window at the ocean. Toshiaki: "...No one." Panel 3: Axellion eats a kelp snack while raising an eyebrow. Axellion: "...Really? No one?" Sound effect: crunch Panel 4: Axellion imagines various Ambassadors dressed in the garments of courtesans from various Izanagi Federation territories. One of the Ambassadors is dressed as a cat maid. Axellion: "Didn't even hook up with any other Ambassadors?" In the foreground, a chibi of Toshiaki looks a little annoyed.* Toshiaki: "No." Page 2 of a grayscale sketch comic. Panel 1: Axellion puts his finger to his chin. In the foreground, an arrow with the word "Inexperienced" is driving into Toshiaki's neck. Axellion: "Huh, okay~ I sorta had the feeling that you didn't have much experience!" Toshiaki, thought bubble: "He saw right through me..." Sound effect: hrrk Panel 2: Axellion tilts his head to the side and smiles genuinely with a blush on his face. Axellion: "But there's really nothing wrong with that!" Panel 3: Flashback to Axellion dressed in his elegant kimono and hairdo as an Ambassador while standing in front of a painted folding screen. Axellion: "I went for you above all my other potential suitors that night not just for your hot bod... Even if that was a part of it" Page 3 of a grayscale sketch comic. Panel 1: Flashback to Axellion and Toshiaki seated opposite each other on the floor at a low-lying table on tatami mats. A circular window has a view of the old Japanese-style buildings outside. Axellion: "Even if your flirting was a bit clumsy, I liked it! Instead of shoving your money or your muscles in my face, you were genuinely trying to court me!" Toshiaki, thought bubble: "Clumsy? Ouch..." Panel 2: Toshiaki looks intently down at Axellion while posed suggestively above him, and they're both at least partially naked. Axellion's eyes are closed and his mouth is open with pleasure. Axellion: "...All I could do back then was spend the night with you. You were still my client, after all." Panel 3: Axellion in the present day has a lovestruck expression on his face. Axellion: "But you totally could've won over anyone you wanted with that kind of charm!" Page 4 of a sketchy grayscale comic. Panel 1: Toshiaki's expression is oddly contemplative. Behind him, he imagines the outline of the helmet he wore when he was a mecha pilot. Toshiaki, monologue: "Anyone I wanted...?" Toshiaki, monologue: "In my past life, I did not consider what "I" wanted. The Deva Bishamonten was nothing more than a weapon for the Izanagi Federation." Panel 2: An imagined glimpse of the side of Shinjiro's head. He's looking back at the viewer. Toshiaki, monologue: "But was there someone I could've considered...?" Panel 3: Axellion leans forward and kisses Toshiaki sweetly on the cheek. Sound effect: kiss Axellion: "Buuuut I'm super glad that I can get you all for myself now!" Panel 4: Axellion snuggles into the crook of Toshiaki's neck with an impish smile on his face. Toshiaki closes his eyes and leans into his touch. Axellion: "So don't use your charms on anyone else, 'kay?" Toshiaki: "Wouldn't dream of it." Panel 5: Dark background. Toshiaki and Shinjiro's intertwined dogtags are visible on it. Toshiaki's dogtag reads "Bishamonten - Toshiaki Mizushima". Shinjiro's dogtag reads "Enmaten - Shinjiro Yamashiro". Toshiaki, monologue: "I have Axellion now. There's no need to think about the could've-beens."

Dialogue: "But the thrusters don't actually move like that. And the weight balance is too back-loaded." Panel 4: Close-up of Axellion's face. He has his tongue stuck out playfully and he's leaning his face on his hand. Dialogue: "Dang, so they didn't get everything right?" Panel 5: Toshiaki leans to the side to get a better look at the Bhairava model. Dialogue: "It's accurate enough." Page 3 of a grayscale sketch comic. Panel 1: Toshiaki reaches out his hand to take the Bhairava model from Axellion. Dialogue: "Let me have a turn." Panel 2: Toshiaki fiddles with the Bhairava model in his hands. In the background, Axellion watches him with an impish smile on his face. Dialogue: "He's actually really cute when he's playing with plastic models like this... It's like he's finally getting to be a little kid again."

Whatsapp meme but with my comic characters #bladeofseafoam #ocsky
A deliberately badly edited meme with the text "What if Toshiaki Mizushima had WhatsApp" at the top with three laughing emojis. Half of the meme is a bust-up drawing of Toshiaki Mizushima on the right. On the left is an edited WhatsApp interface with profile pictures representing each character who has a Direct Message channel with Toshiaki. Axellion's message reads "I NEED cock Toshiaki :p (stuck out tongue emoji)". Shinjiro's message is a notification for 10 missed calls. Angelo's message reads "Fucking KILL YOURSELF". Rashida's message reads "I NEED military secrets". Safiya's message reads "I NEED nanomachines". The Admiral's message reads "Kill yourself NOW, Bishamonten".

Cleaned up an old doodle of Rashida and her INPU-00 mech with its Ushabti drones #bladeofseafoam
Digital drawing in an ink-and-watercolor esque style. The gold, white, and black INPU-00 mech stands centrally above pale blue water while holding a golden khopesh blade in its left hand and firing Ushabti drones shaped like sarcophagi. The dialogue box "Go, Ushabti!" comes from the head of the INPU-00, representing the verbal command of its pilot Rashida. In the foreground, Rashida is visible from the shoulders up to represent what she looks like inside the INPU-00's cockpit.

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.
