An art piece drawn by Snivy of Yuma and Desuhiko from RainCode. Desuhiko is a Werewolf and Yuma is a Reaper. Desuhiko is in his full werewolf form, his tail wagging as he nuzzles Yuma who is laying on him. Yuma has his arms behind his head and is looking smug as he gazes at Desuhiko.
I recently commissioned the lovely @snivyartjpeg.bsky.social to draw my Reaper and Werewolf boys! Desuhiko looks so floofy and happy and Yuma looks so smug!
I adore this so much! And look at the beans! Thank you so much Snivy for bringing this idea to life!
#raincode #レインコード #kokobolt #ユマヒコ
A digital art piece of Yuma and Desuhiko from RainCode. They are dressed in Rindude's Swap AU outfits. Desuhiko is the protagonist who made a pact with Shinigami and Yuma is the disguise detective. Desuhiko and Yuma are sat on the sofa in the submarine. Both of them are blushing heavily as they face away from each other, goofy smiles on their faces as they both think the same thing. Above them is a thought bubble which shows their same thought which is them kissing the other surrounded by hearts. Shinigami is behind the sofa and looking at Desuhiko (her master) disapprovingly as she can read his thoughts.
I drew a b-day gift for one of my Discord/Tumblr pals! They're a huge fan of Rindude's swap AU (Desuhiko made the pact with Shinigami and Yuma is the disguise detective. All the NDA swapped fortes too) so I drew Yuma and Desuhiko being silly dorks for them!

An art of Yuma and Desuhiko from RainCode. They're in their God AU look from my AU. Yumoon is holding vampire bat versions of himself and Desuhiko who look queasy. He looks at Desunhiko a melancholy smile as he says, "No, Desuhiko-kun. They're vampires, and you're the Sun. You're making them sick. Please keep your distance, okay?" Desuhiko looks a little heartbroken as he just wanted to pet them, but understands.
Bonus art with Desuhiko making the Vampires sick. Problems when you're the literal embodiment of the Sun 😔 (I'm trying out a new quick colouring style)
#raincode #レインコード #kokobolt #ユマヒコ #myart
An art of Yuma from RainCode. He's in his Moon God look from my AU and he's floating above the ocean. The Moon is behind him glowing as he holds a vampire bat Yuma on his right index finger and vampire bat Desuhiko nuzzles into his left hand. Yuma at peace as he looks at his vampire bat version of himself who is confused.
I drew my Yumoon with my friends' Vampire AUs (@snivyartjpeg.bsky.social and Dunia). I've had this idea since 2024! I just liked the idea of Yumoon being sweet to these vampires.
I honestly adore how this came out.
Also, bonus art in thread below!

An art piece showing every piece I've done throughout the year of 2025. There's nothing in January but every other block is full. Template by ReIN1324
Summary of 2025 Art!
I couldn't draw anything in Jan, but I'm happy with how much I drew! This was my best year of art! I learned more about anatomy and using references. Here's to 2026 as I still have a lot more RainCode arts I want to draw!
#raincode #レインコード #kokobolt #ユマヒコ #myart
A screenshot from AO3 that says: 'The Congestion Curse' By BrightStarWrites Summary: Yuma is struck with a sudden illness which confuses everyone. Reapers are immortal and should not be capable of getting sick. While the other Reapers are more confused over if what Yuma has is dangerous or worse, contagious, Desuhiko somehow breaks the laws of the Reaper Dimension and jumps through a portal. Mortals should not be able to enter their plane of existence after all. More concerned about Yuma’s wellbeing, Desuhiko vows to protect his fellow pack member and nurse him back to health. SPOILERS FOR RAINCODE CHAPTER 5 AND VIVIA’S DLC! NOTE: This is non canon to the AU, just a little fun piece and a thank you to Pixel for the birthday art they drew for me!
New fic! This one is based on my fic 'Hallows and Howls' but is non canon!
Reaper Yuma has been struck with a fever and it's up to Werewolf Desuhiko to take care of him. Desuhiko also breached the Reaper Dimension.

A screenshot from AO3 that says: 'Drunk and Ghostly Visions' By BrightStarWrites Summary: After drinking far too much with the chief, Yuma Kokohead was incredibly drunk. As Shinigami helps him avoid the Peacekeepers by using the pact chain to guide him to safety, Yuma seeks refuge in Desuhiko Thunderbolt’s hotel room. But how will Desuhiko deal with the wasted trainee flirting with him? And who on earth is he talking to? SPOILERS FOR RAINCODE CHAPTER 2 AND DESUHIKO’S GUMSHOE GABS!
Another Kokobolt fic! (Are we really that shocked though 🤣)
Yuma gets drunk and gets chased by the Peacekeepers. He seeks shelter in Desuhiko's room, but how will Desuhiko deal with Yuma talking to a hallucination?

A screenshot from AO3 that says: 'The Tip of the Tongue' By BrightStarWrites Summary: Yuma and Desuhiko have had a rough day of investigating, have reported to Yakou, and have now returned to the Sun and Moon hotel to relax and get some much needed sleep. When they end up kissing however, Yuma feels what seems like scars in Desuhiko's mouth. What's going on with Desuhiko, and can Yuma get him to open up? SPOILERS FOR DESUHIKO'S GUMSHOE GABS!
Another Kokobolt fic!
Yuma and Desuhiko relax after a rough day of investigating, returning to the hotel. They end up kissing and when they do, Yuma feels scars in Desuhiko's cheeks. Hopefully he can comfort him.

This is from my new chapter of Hallows and Howls! One reason it took so long was because I wanted to draw art! But yes, they finally kiss!

A screenshot from AO3 that says: 'Hot Blooded' By BrightStarWrites Summary: After trying and failing to find the secret lab, Yakou suggests that he and his fellow detectives go to a sauna to help detox and also warm up from the cold rain. How does it go, however, when Halara and Desuhiko turn it into an endurance match? SPOILERS FOR RAINCODE CHAPTER 4 AND DESUHIKO’S GUMSHOE GABS!
Fic time!
This fic was written as a slight joke because I overheat in my Desuhiko cosplay, but I had so much fun writing it! I hope you all enjoy! Let's see if you can spot the Danganronpa reference in here 🤣

A screenshot from AO3 that says: 'Unearthed Scrolls' By BrightStarWrites Chapter 10: Souls United (Part 1) Summary: Kurumi was still confused about what exactly had happened which had caused the permanent rain clouds to vanish from Kanai Ward. All the fake humans had also disappeared with them as well. An answer was close at hand however, as Makoto Kagutsuchi approached her with an offer she couldn't refuse.

A screenshot of AO3 that says: 'Tricks that Befall on All Hallows Eve' By BrightStarWrites Summary: Yuma Kokohead didn’t really celebrate Halloween. As a Reaper, he normally spent the holiday reaping souls or hiding from Shinigami and Makoto to not be on the receiving end of their pranks. This year however, he’s decided to hide out with Desuhiko Thunderbolt until the day blows over. Imagine his surprise however when the strange artifact he grabbed from his latest soul retrieval causes way more trouble than one of Shinigami’s pranks ever could! How will he deal with being a werewolf, mortal and easily hurt, and how will Desuhiko cope with suddenly being an immortal Reaper? (Takes place after chapter 4 but before chapter 6) SPOILERS FOR RAINCODE CHAPTER 5!
Fic time!
Happy Halloween!
Here's a fic set in my Hallows and Howls AU! Body swap but with a twist! It's a Supernatural Species Swap!
Hope you enjoy Werewolf Yuma and Reaper Desuhiko and their shenanigans!

This is a redraw of an old piece of art I did back in March 2024! I think Desuhiko's head looks a lot better, as does Yuma's. I also made the blanket more Yuma themed! The Pokémon plushies are from my friend's other AU

A screenshot from AO3 that says: 'In a Pickle' By BrightStarWrites Summary: Yuma and Desuhiko are spending time away from Kanai Ward and enjoying the sun. Unfortunately, Desuhiko is not having the best time as the current heatwave means he cannot wear a hoodie.

Fic time!
So I decided to write a little Summer date oneshot where Yuma and Desuhiko go get burgers! I hope you enjoy!
