[TenOjE YoogO]

Voice: low

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 Rintarou nicknaming him "Mr. Braun" after the inventor of CRTs and the common Japanese name for CRTs, "Braun Tubes".

While appearing as a tough and menacing man and often using this demeanour to jokingly bully Rintarou, 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.

Yuugo has a bad temper, and is very easily annoyed by Rintarou's mannerisms as well as his "experiments" upstairs. He regularly threatens to raise the lab's rent money should the experiments continue to disturb him, though this has never actually happened.

In the presence of both his daughter and Rintarou, he would often attempt to "protect" her from Rintarou, whom he sees as a "pervert", though he was likely joking.

Background: Yuugo was an orphan living in Paris. He grew up living a rough life in the sewers. He is Rintarou Okabe's landlord and the owner of the CRT store.
