In 2018, it was announced that Uchikoshi had left Spike Chunsoft and formed a new, independent video game developer, Too Kyo Games, together with writer Kazutaka Kodaka and composer Masafumi Takada, both of whom previously worked on the "Danganronpa" series at Spike Chunsoft. Other "Danganronpa" staff members, and Uchikoshi's fellow "Infinity" writer Takumi Nakazawa, also joined the company. At Too Kyo Games, Uchikoshi has the role of scenario writer and game director, and is writing two video games: "Project #1", co-written by Kodaka; and "World's End Club", an action-adventure game involving children playing a death game.
