Coffee Buns is an 18+ Ren'Py visual novel by Cinnamon Switch, set two years after a tea that turns drinkers into animal-like people. You play Leonardo Bianco, a café barista whose boss wants to try the transformation to draw customers. Through a local business connection, Leo and coworkers get a chance to change, and the tea produces more unexpected effects for him. The game uses 2D CG art and explores transformation, romance, and monster-girl themes.
Current build is v0.9.3, dated July 18, 2026, and described as the final early-access release rather than the completed 1.0 version. Development continues, with remaining story and art planned for the full release. It runs on Windows, Mac, Linux, and Android, in English, without censorship. The latest update adds a new story, The Final Roman Date, featuring Leo and Roman's last tea-related outing and a reckoning of their relationship status.
Developer's description
Coffee Buns is an 18+ Transformation Visual Novel set after the events of
Mice Tea
. It's been two years since since the worldwide release of Kemono Tea, which turns the people who drink it into anthropomorphic animals. Society is still adjusting to the idea of real-life furries, but that doesn't mean you can skip your day-job.
Leonardo Bianco is a barista at a struggling café. His boss feels like hopping on the furry train might be just the thing to attract customers to the floundering business. Via a connection at another local business (which some returning readers might recognize), Leo and his co-workers are offered a chance to try transforming themselves. The tea works as advertised, but for Leo, there's more changes he didn't anticipate.
v0.9.3
This is the final early access release of Coffee Buns
That's right, the next time you'll see an update to Leo's story it will be in the final 1.0 release!
We'd like to thank everyone who helped and supported our development from those who donated to those who submitted feedback and corrections to those who drew fan art and even those who just told their friends about it.
We still have some development, including some remaining art and story, but we're holding that for you all to see once we're fully released.
So let's see what's in this final EA update!
New Story - The Final Roman Date
Roman fans have been patiently awaiting this moment, and we hope this update is worth the wait! It includes the final tea-powered outing by Leo and Roman, and a final reckoning of the status of their relationship. Can Leo promise he can be what Roman wants in a partner and can he keep those promises? Keep reading through the end to find out!
New Art - New CGs from The Transformistress
Mira supplied us with two new CGs, or more properly two CG sequences. She's been looking forward to this flying date for the whole development, and we got to it just in time. There's lots of alternates and stagings and even a little animations thanks to the inventiveness of Jess, our sprite wrangler, so please check it out!
New Art - More sprite elements and two new NPCs
Building off the work he did for last release, KDhynamo has produced even more sprite variations for our cast, including another two-character sprite that appears in the story's ending. There's once again too much to show or mention every permeation, but here's Boss in her hat and sunglasses and Leo knitting for a taste.t
Also, we know ram shortages have been threating technology and games, but we got a hold of one so we're all set now!
We hope you're as excited as we are to see this milestone come to pass, but there's still more Coffee Buns to make, including adding voice acting, and we'll keep you abreast of the final stages these last few months.
v0.9
New Story - Ash Date 3
As much fun as Leo has had on his dates with Ash, he's still not much closer to knowing where the two of them stand in a relationship. He figures going out to a concert might be a chance to get to know the real Ash, such as there is one. It might also be the perfect time to take the initiative in their physical relationship as well...
The new story extends beyond the date though, with new dialogue and character appearances from Day 31 onwards, so stick around after this new chapter to see what's changed.
New Music - Four New Tracks by Will
Will's been busy for some time with projects like
Chrono Gear
and
Unearth
, so it's been a while since we've had some new tracks from him. He's returned with a vengeance with four new tracks in this update for your listening pleasure!
All are variations on existing character themes, mostly for more low-key scenes when their regular themes might be too overpowering. However, the biggest addition is a new theme variation for Leo that plays on the last day of the story and is an audio culmination of his journey in the narrative. Give it a listen as you see the new dialogue in the final scene!
New Art - Five New CGs from The Transformistress !
Mira has once again showcased her talent and prolificacy (had to look that up) with five all new illustrations for this update. Two of them are featured in the new story updates, one (shown below) is a totally new addition to something that was only in sprite form before, and two are redraws of exiting CGs now illustrated by Mira. Check out the Day 3 and Day 5 (at Ash's) scenes to check out the new art.
Naomi Goes Vroom
New Title Illustrations
We've updated the main menu of the VN with new illustrations of Leo and Bonnie! We weren't satisfied with the composition and not being able to show both at once, so KDhynamo went ahead and made some all new illustrations. They might not appear if you've already completed the story, but we'll have a gallery in place once the final title illustration is added.
v0.8
New Story - The End
This update has three whole days of story that starts with Day 31, a full month after this whole saga started. Leo's been coasting along for some time now, but with such a milestone he (with some prodding) has determined it's about time to figure out where he stands as far as his identity goes. It's a decision that's going to have immediate consequences that spin out to the conclusion of the story.
New Art - New Sprites, New CGs, New Characters!
We mentioned last month that our artists were working on this update at the time, which we think will show in the amount of new art we've got in store for you. How much art? How about:
Three new finished CGs, some with double digit amounts of alts
Three new outfits
Two new TF forms
Several new characters
That's a whole bunch as we pull out all the stops for the conclusion of Coffee Buns!
v0.7.1
New Story - The Convention with Ash
Ash has already invited you out to accompany her in her cosplay endeavors at the local convention, but now you can take her up on the offer. Ash hasn't yet revealed what she and Leo will be wearing, but once both are at the con she shows off a pair of outfits that readers might find familiar.
Our favorite skunk has already displayed her love for dressing up and inhabiting different roles, but this update offers a closer and deeper look at her motivations and preferences for her hobby. Plus there's some pretty dresses to look at!
New Art - Two new CGs from The Transformistress
We're not going to design two dresses like that without showing them off, and Mira's come through with two illustrations of Leo and Ash strutting their stuff at the convention!
New Art - Four New Sprites from KDhynamo
The cosplay outfits are some of the most involved outfits KD's drawn for the VN so far, so that was probably all he worked on, right?
Wrong!
We tempted him with drawing two new office attire outfits for Leo and Ash, and he came through with two fantastic designs.
New Art - New in-progress CG from UltraBondageFairy
The visit to the con turns into something a little more once the duo get back to Ash's apartment, and UBF gets a chance to depict the two in their outfits for a sexy scene at the end of today's writing. UBF put a lot of care and detail into the dresses and we hope you enjoy it as you read the first intimate scene featuring Ash and Leo.
New Art - Finished BG of Boss's Home from HeartGear
Heart completed the background we introduced in the last update and you can finally see Boss's place in its full glory.

DJ FroG2026-03-02★★★★★
This game is technically well-made and visually impressive, but it struggles to deliver a satisfying payoff. The art and character designs are genuinely strong, and the transformation sequences are clearly crafted with care. The opening half builds an engaging journey…
keksx42026-01-12★★★★★
I didn’t play Mice Tea , so I have nothing to compare like others. But I can say this one is really rough, especially at the end, it plays more like an episode cliffhanger than a proper finale. Most choices…
Greatazuredragon2025-09-26★★★★★
If there was half stars I would give this 3.5, but since there isn't and in my opinion is closer to 3 than 4, 3 it is. Well written and with great visuals, but saddly there aren't many 'options'. Most…
