Steins;Gate - Onshuu no Brownian Motion

Yuugo Tennouji, better known in Steins;Gate as Mr. Braun, has a past deeply connected to SERN and the Rounders. This spin-off moves backward through key dates from 2010 into the late 1990s and early 2000s, revealing how Yuugo became entangled with the organization, how his life intersected with Tsuzuri Imamiya and Suzu Hashida, and how the choices of those years eventually shaped the man who would later run the CRT shop beneath the Future Gadget Laboratory.
