Alter Ego Sis a new visual novel coming to Switch in Japan in Spring 2020. The game is a follow-up toAlter Ego, a free-to-play mobile VN which launched on June 29, 2025 in Japan. The game is developed by an indie game studio named Caramel Column.
Alter Ego S, just like its predecessor, is a visual novel where choices matter. Guided by a woman named S, the game asks you to make many different choices through reading books. These choices end up creating a portrait of your personality. It’s a game which helps you “find oneself”. The original game on mobile included many references to psychanalysis authors and books, with an actual list of said books on theofficial site.

The originalAlter Egogot more and more popular from mouth to ear and ended up downloaded over 500,000 times. This might not seem like a high figure, but it’s significant when it comes to a non-gacha game where people won’t make multi-accounts or reroll. The originalAlter Egodid have microtransactions though. You could buy more “Ego”, the currency needed to read more books.
Caramel Column’s president Maki Ono was even present at C96 last August to sell an Official Fanbook ofAlter Ego, and it was met with a lot of success.
A demo ofAlter Ego Son Switch will also be playable at Tokyo Game Show 2019, at the Indie Games Corner.
To be honest, I had no idea this game even existed until I saw the announcement ofAlter Ego S. While I have no interest in philosophy and psychoanalysis, I’ll have to try out the original one of these days to see what’s the fuss' all about. SomeAlter Ego Sscreens are included below.
IfAlter Ego Sgets huge in Japan after its launch on Switch, it might get translated one day.
