A downloadable Visual Novel for Windows, macOS, and Linux



Inna is 22 and a social recluse with a most unusual skillset: assassination. Under pressure of changing her ways, she takes on an assignment very different from what's she's accustomed to. Her new job requires her to look out for a 17-year-old girl while she is in college. What sounded like an easy piece of work – with the plus of turning over a new leaf – turns out to be quite the predicament for Inna... in more than one way.

This release features 3 complete endings, and 1 ongoing one.


Inna Antonova:

The protagonist.
Inna generally avoids social interactions, save for the ones with her contacts and clients. Contrary to her "cold" professional image, when relaxing at home she could be mistaken for any other regular 22-year-old girl.

Lillian Garland:

The romantic interest.
Lillian is a 17-year-old, outgoing college girl with a stubborn streak that she most likely inherited from her father, a successful lawyer.

Samuil Atonov:

Inna's adoptive father.
Currently in the hospital, his health waning with each passing day. He's the main reason why Inna feels compelled to change her ways.

Ray Garland:

Lillian's father.
A well-known and ambitious lawyer. He's rarely home, but when he is he tries to make up for lost time by spending lavishly on Lillian.


Inna's primary contact for work opportunities.
A mysterious, brusque man with a mind for business. He appears to have some shady connections.

Sorry for the late reply! I have not abandoned this game – I've been pretty busy over the past couple of years, but I have been working on it on and off. Recently, I worked out a schedule and have been actively working on the script (it is already 2.5x the length of the 1.2 release). I don't want to announce anything until I finish the script. Thank you for your continued interest!


i'm so glad to hear that! And i'll happily wait until the final result, i'm really excited to play it again, it's been 3 years after all <3


It's been quite long, hasn't it? Thank you for your continued interest!


i think i haven't played any more VN since 2015/6 so this will be a comeback for me too eheh


That's great! <3


Nice novel. I could gladly help with russian lines/names, but it seems like its abandoned, which is sad. 


Thank you for your interest! This game has not been abandoned, I have recently started working on it a lot more actively. And I can always use help with the Russian bits in the game! Is there a way I can contact you?

I really like this game. 

Nice artstyle. Good looking characters. Nice backgrounds, Good music 

Great plot. With few endings based on players choices. It's great. I like when game allows player to make decisions :)

I can wait for ongoing ending :) 


I'm very late, but thank you for playing! I'm glad you enjoyed the game. I am currently working on the final version~

I rather romance Inna. I wish the main character was Lilian. 

Is it me or does Inna Antonova look an awfully lot like Nico Robin?

I like Nico Robin!

Is it me or does Inna Antonova look an awfully lot like Nico Robin?

Thanks! And I am working on that!

One of the best visual novels I've read through

Oh wow, that's so motivating to hear! I hope you will enjoy the final version as well. Thank you! (And sorry for the super late reply.)

I'll definitely be around for the final version

I'm glad to know that!

Literally made an account just to comment on this visual novel. It is amazing, I loved every second of it. The art is perfect for the game and I love the music too. The characters are all lovable and I really like  the way Inna and Lily connected. That was one of the reasons I got pulled into the game. I would love to play the full game when it comes out, and even if it doesn't come out it was still an awesome game. It had a great story and great characters. Can wait until the full game, keep up the good work.

That is simply lovely to hear! I'm so happy you had a good time with this VN, the team put in so much effort. And yes, there will be a full version, I am actively working on that. Thank you for your lovely comment and sorry for the super late reply!

Linux pls

Hi! The download is for Windows, macOS, and Linux.

This Visual Novel is simply amazing. I was hesitant at first but I found myself being dragged in by the main characters feelings and Lily's energy. It was adorable, funny and by the end I could not stop smiling. Thank you for making my day.

Sorry for the late reply! I'm happy that Inna and Lillian were able to pull you in – if it  brought a smile to your face then the route did it's job! Thank you for playing!


The art is beautiful . The setting are well done . And suprinsingly it's funny like hell . If I had to name something that was a bit of a let down , that would be the main character background . But other then that it's well done .

Thank you .

Sorry for replying so late! I'm happy you enjoyed the game. And the final version should rectify that issue – Inna's past will not be explored in full detail, nor will there be lengthy flashbacks, but you should still get some insight into how she came to be who she currently is.

Thank you.
