Sensei Overnight is a Ren'Py dating sim from Pers0nas, built around 3D CG and animated visuals. You play Janu, whose name can be changed, after a quiet janitor suddenly becomes a sensei overnight. The story follows his attempt to understand the new job, the students he now meets, and the unfamiliar lifestyle around him, while mixing fantasy, horror, and humor. Adult content is present, and all characters are stated to be 18 or older unless noted otherwise.
The current build is v0.19.0, released on August 20, 2023, and development appears ongoing. It runs on Windows, Linux, Mac, and Android, with English text and no censorship. This update adds more than 600 images, 12 events, including two main scenes and character events for Nokana, Roni, Hana, and Tami, plus four new tracks. It also includes grammar and bug fixes, and lets players replay the new events with hidden or additional dialogue.
Developer's description
If you were to spend so much of your life doing one thing in one place, to move to a different place to do the same thing, would that be considered a 'fresh start'? In Sensei Overnight, Janu (or whatever you change his name to) gets this question answered for him, as he goes from a nonchalant janitor to a sensei in, well, overnight. He has questions, and nobody is giving him clear answers, so what else is there to do than explore this new lifestyle he's been gifted, along with his new students.
(All characters are 18+ unless stated otherwise).

KNOWN BUG - If you're on android, you may need to uninstall any previous versions of SO before installing 0.2.0. Sorry in advance!
v0.1.5.1
Here's a small update for Sensei Overnight, I've corrected a lot of typos thanks to MadFlexer's help over in the discord. I've also redone the scenes from the Dayai dream, and, most importantly, you can now
change the name of the MC
. If you start a new game, you can do this right away, otherwise, you can change it on
weekend mornings
. MC will come up as '[player_name]' if you're starting the game from a save file, so just change it in the morning on weekends and all will be well.

- Over 200 new images
- New music
- Corrected typo and grammar mistakes from 0.1 version.
- 4 new main events
- 2 new characters

Bugbear322023-12-01★★★★★
I love the variety of girls. I like the art style. I don't hate the attempts at comedy. These are the only nice things I can say about this game. Even with a walkthrough, this is a frustrating exercise in…
Brojo2023-08-18★★★★★
It's just fine. I do dislike when it's not really spelled out that a certain path is closing for any of the characters at any particular time. There isn't much to go off of on some of the shorter interactions…
Kaintfm2023-08-03★★★★★
Sensei Overnight pays homage to other popular AVN titles while forgetting the aspects of those titles that made them so popular. A near complete absence of drama coupled with the majority of scenes quickly outstaying their welcome and a free-roam…
