Taeko's House

Taeko's house is mentioned in most blog posts of the series, relating to where her get-together gig was held, and where her friends spend their free time hanging out at when she's not supposed to stay in the house alone with her sister, Rena Lunenburg

History
Stating from the very first blog post, from official evidence, most start of from Taeko's house, and it's been the way for other houses also. It appears like Mai Rockbell, she has "Ancient Stuff", in her basement.
