In Your Veins
There is a Browser and Download version of the game available. The best performance of the game will be the downloadable version.
You are a monster hunter with one goal—to save the world.
An ancient evil has reawakened, and it’s up to you to prevent the world from being consumed by its darkness.
But you can’t do it alone.
Your three companions are by your side in this perilous journey, each a monster in their own right. Arden, a harpy who has not left your side since you first met them. Katya, an apprentice witch who holds a fascination for you. And Cassius, a dangerous vampire lord that you have ensnared.
With their help, and with the aid of a dangerous gambit involving the blood of the dead goddess of the sun, you might just have a chance.
But their eyes watch you in the dark, and you cannot help but wonder if they are only by your side from a sense of duty alone.
This game contains Act 1 of the story made for Yandere Jam 2026. A full release of the game will come out in 2027. It will be well over double the length of Act 1 Release, and finish the story with a variety of endings based on choices and romances. There will be three full romance routes, with a potential secret fourth route if there is considerable interest in him!

This was wonderful! Arden is my absolute favourite, their design, personality, species...Oh I love, love , love! I love the MC's personality choices as well. The background music is wonderful too! The Sun Templar interests me so much. Is this the potential secret fourth route? Even if not, I'm still very interested so I do hope there is enough interest that we see this fourth route. I look forward to the next act. Will the full game be behind a paywall? :)
(Apologies on any mistakes or if any questions have already been answered!)
Very intriguing so far! I'm a massive simp for Arden, they're so cute and I'd give them the world. I like that they have their own unique communication style with MC. Yanking Cassius around was fun too, I only wish the kiss scene had a 'dominant' option-- after choosing every dom option up to that point, it felt a little disappointing to have my MC suddenly act all passive and let Cassius take the reins.
The plot itself is interesting and I'm curious about how it will resolve. I'd like more chances to see details about the MC's history and religion and just generally more worldbuilding/backstory, it seems like there's a lot going on and the reader is much less informed than the characters.
I was expecting a lot from this game and was not disappointed! Every character brings something awesome to the table. The art is gorgeous and the lore fascinating. It made want to play the second act so badly.
I would love to help the game reach a wider audience by doing the Spanish localisation for free. Please hit me back if that is something you are interested in.
Wishing you great success!
PLEASE PLAY THIS GAME ITS SO GOOD IM SO IN LOVE WITH THWE STORY. I am also hopelessly in love with Arden. I can't wait to see where the story goes!! I really had a lot of fun playing this and instantly fell in love with the story and the vibes!
I really love the way the player character's personality can come off differently based on your choices and I LOVE that they're explicitly stated to be strong. I just had to say that. This made me realize how few competent MC's there are.. ANYWAY I LOVE THIS SO MUCH AND I REALLY CAN'T WAIT TO SEE MORE!!!!!!!!
wow! such a beautiful game and one whose characters are equally as enjoyable. i can't wait for future acts!
GUH.. i need Cassius.. cannot wait for the next acts!!
Literally THE BEST GAME EVERR!! I can’t WAIT till you release the whole game!
Amazing vibes! Arden is precious 💙
Oh my goodness, this is a beautiful game and I am so excited for Act 2. The character designs are gorgeous and the lore is so fascinating
I've only known Arden for an hour and a half, but if anything happened to them, I would kill everyone and then myself. Or whatever the quote was. The art is gorgeousssss, and I really like the setting
this was good good. I’m excited for further updates. I can’t choose between Arden and Cassius lol
theyre so gorgeous
Arden is so cute! I can't wait to fluster them more in the next act.
so good
I really enjoyed this! Thank you!
Really hope I'm not the only one curious about the Sun Templar the MC pisses off. Love this so far!
Cassius my beloved ꒰⑅ᵕ༚ᵕ꒱˖♡
Monster? Yandere? Adventure? Fantasy? I'm intrigued
THEY'RE ALL SO GOOD, looking forward to seeing this story to its end
is it just me that thinks Katya and Arden are a bit 👀👀
Katya keeps compliment them,, they're so cute tgt ♥️♥️♥️♥️
Poly relationship with the both of them 🙏🙏🙏
holy crap this is so good!!!!! i cant wait for act 2!!!!!! i absolutely adore Adren <333333
I can't wait for act 2! I love Arden <3
The art looks gorgeous, I can't wait to play the game!
I loved this game!!! The story is so compelling, and the character interactions are fascinating.
I'm OBSESSED with Cassius, OMFG! The concept of yanking around a dangerous vampire lord on a leash kills me, hahaha. I loved the adventure and the unlikely found family - a monster hunter with 3 monsters? STAHP! I'll be back for Ch. 2!
I ABSOLUTELY LOVED THIS- IM SO EXCITED FOR THE FULL GAME
How is this a yuri game when you can be a man and romance men
you can literally be anyone and date a woman, a man and a non-binary person. so yes, obviously, yuri is an option. any other question?
I loved this and will definitely keep following it!
CASSIUS OMFGGG HES SO AMAZING! Love him and this game so much, I hope for more in the future!
Oh my god this was amazing!! You guys never disappoint. Are you planning on doing voice acting for the full game? If so, I'd be happy to help out
ARDEN MY BELOVED!!!!! I am going to kiss them so hard u have no idea
ARDEN FLASH US!!!
arden and cassius my babies omg
Holy shit, I've never been so equally enamoured with all the LIs in a game before. How am I supposed to choose just one route...would it be too greedy of me to want all of them (at the same damn time)? /silly
!!!Potential spoilers below!!!
I was pleasantly surprised by how forthright each of the LIs are with their fondness (okay maybe 'fondness' is putting it too lightly) for the MC. Arden aside, I didn't think Katya and Cassius would be that endeared with MC as I assume we haven't been travelling together for that long. Cassius especially since we did put a collar on him (but then again the freak likes it so maybe it doesn't count).
Katya's unabashed care (and blatant favouritism lol) towards MC is so sweet and makes me twirl my hair and kick my feet. I honestly expected her to be standoffish or a little more reserved but wow I'm so glad I was wrong.
And Arden...oh sweet, kind Arden, I have many things to say, but its 3 a.m. and my brain is slowly powering down as I type all this. Just know that I would give them the world if they asked (and even if they didn't...oh my darling harpy they should ask for more things I would give it to them...)
I am stoked to see how the rest of the story unfolds. As a LOTR lover, the plot of going on a journey with a party to defeat a newly resurrected world-ending evil is really scratching that Tolkien-loving itch in me.
Thank you for sharing such a beautifully made game with us. I hope development goes well, will be waiting patiently until the game's full release!
Aha... so whos yandere? hehe~
I loved it!! I got flashbanged every minute tho 😭 Im still waiting for more!!
Arden is so cute ohh my god. I need them. I need to cradle their face in my hands and just kiss them. I HAVE to save the world specifically so we can settle down and live happily ever after. Nothing else matters at this point. ARDENNNN I LOVE YOUUU
I CANT WAIT FOR MORE AHH I LOVE THEM ALL <3
I've been trying to find games like these and most of the good one's I wanna play are not for mobile this was sooooo damm good!!
Love for giving us options to flirt with everyone lol😋and also Arden??he is MAJESTIC,the style and everything about this whole game is sooo cool
The writing is already amazing and i'm invested! I love Arden soo much, im so excited for the upcoming acts ˊᗜˋ!
