About the Kono mama da to Otouto ga Techno Break de Shinjau kara Kozukuri! English patch

After their parents divorced, the protagonist's older sisters went to live in America with their mother. Now, about ten years later, all three are suddenly back, and they have grown up in ways he was not prepared for. Worse, he has been holding himself back during exam season, and the sisters happen to overhear him once it is over. Their solution to his problem is outrageous, and it kicks off a very eventful life under one roof.

Kono mama da to Otouto ga Techno Break de Shinjau kara Kozukuri! is a fully voiced adventure game from atelierKaguya, released in 2017. It runs around ten hours and is a sweet, comedic sister-focused nukige with three older heroines.

This English patch translates the game's story text, 25,163 lines of dialogue, narration and choices, by replacing the game's message.dat file. The user interface is not translated yet.
