ONE. – Walkthrough & Guide | ONE Remake ~Kagayaku Kisetsu e~

ONE. (ONE Remake) is a 2023 remake of the 1998 visual novel ONE ~Kagayaku Kisetsu e~. It has a long list of choices to get onto one of seven routes, with one locked. 

The remake is available on both PC and Nintendo Switch. While the 1998 version of ONE ~Kagayaku Kisetsu e~ included adult content, the 2023 version of ONE does not.

This guide will tell you about the choices to access the various endings. There are no Steam achievements

Route Order

Any heroine route can be chosen first in ONE. but you will need to complete any other route before unlocking the route for the protagonist’s male friend Shun Hikami. I recommend that you only play this route after completing Rumi’s Nanase’s route as it shares many choices.
