Synopsis
Yuugo Tennouji runs the Braun Tube Workshop, a CRT-television shop, and is the landlord of the building where Rintarou Okabe rents his lab. He is married to Tsuzuri Imamiya and raises their daughter, Nae Tennouji, whose safety he will go to any length to protect.
His gruff manner and habit of scolding Okabe over the noisy experiments upstairs, which earned him the nickname Mr. Braun for his obsession with old CRT sets, mask a genuine fondness for the lab members. But that same gruff exterior also covers a far more dangerous double life.
An orphan from Paris once recruited by SERN, Yuugo secretly directs a squad of mercenaries called the Rounders under the alias FB, unknowingly giving orders to Moeka Kiryu among others. When Okabe finally exposes the deception, Yuugo is forced to confront how much damage his double life has caused, and the fallout ends in tragedy that reshapes his family's future for good.
