Yuugo Tennouji

Yuugo Tennouji is Okabe's landlord and the owner of the CRT store.

Personality
He has a great passion for CRT Television and refuses to upgrade to any other type. This coupled with the fact he owns a CRT store has resulted in Okabe nicknaming him "Mr. Braun" after the more common Japanese name for CRT, "Braun Tubes".

While appearing as a tough and menacing man and often using this demeanour to jokingly bully Okabe, he actually has a soft spot for the lab members and cares about their well-being. His daughter Nae is his top priority and he will go to desperate lengths to ensure her safety.

Background
Yuugo was orphaned in Paris and spent most of his childhood living a rough life in the sewers.

At some point during this period, he was contacted by SERN and offered a position as a mercenary, this provided the money he needed to get out of the slums. After a while SERN ordered him to go to Akihabara in Japan, it was here that he met Suzu Hashida, his neighbour, and Tsuzuri Imamiya, his future wife.

Sometime prior to the first D-Mail, Tennouji recruited Moeka Kiryū into the Rounders and communicated with her as "FB".

Appearances
Yuugo appears as a side character in Steins;Gate and most subsequent spin-offs, with the exception of Braunian Motion of Love and Hate, in which he is the main character.
