Horizon is a Ren'Py adult visual novel by KawaiiSukebe, presented with 3D CG visuals. You play as Hirase Tatsuya, a man whose father has disappeared and whose ex-girlfriend ended their relationship without a clear reason. Left with an empty heart and a dull routine, he becomes drawn into events that may affect the country or the world after a fateful meeting. The story follows him as he uncovers secrets behind his father's disappearance and experiences bittersweet encounters with several girls, blending fantasy, harem, and superpowers themes.
The current Early build is v0.4, released on January 25, 2026, and development is ongoing. It runs on Windows, Linux, Mac, and Android, with English and Chinese language options, and it is uncensored. The v0.4 update added about 1300 new renders, 23 new animations, fresh music and sound effects, and new story content for Ayase, Miharu, Chika, and Kaho. It also added one scene with side character Maki, an option to disable in-game KS commentary, and brought back the menu music from version 0.1.5.

--------------------------------------------------------------------------------------------
The gallery will be reworked in the next update, that's why I removed it for now as I'm not satisfied with it.
I'm also still learning how to implement variables in the game, so for now, the choices in the game will not affect the plot, yet. In next version I will put in the real choice systems, and there will be scenes that will activate depending upon the choices you made.
The visuals and some other little things will also be remade in the future as I have gotten better at making scenes and renders. The images in the current game looks so bad(I know), but I will remake them~
That's more or less everything about this update for now. Like I said, I'm getting better and better at it, so things will be improved as time goes on.
Sincerely, KawaiiSukebe

Honestly just couldn't enjoy it. Writing is terrible, with over the top anime style writing that no real person would say, combined with sayings that just don't make sense. I understand the dev, isn't a native english speaker, but its…

I don’t usually leave low ratings, but this one just wasn’t for me. The renders and animations are genuinely good, and a few characters had potential, so there is effort here. My main issue is with the writing and character…
Pseudanynm2026-03-27★★★★★
I will keep this short, the renders are one of the best I have seen in hs2, the mc is not a creep and pervert(I mean he is in some moments when needed) the action thing might not look good…
