Imaizumi Brings All the Gals to His House manga volume 3 features story and art by Gorou Nori.

What do you do when you have three of the hottest girls in your school lounging around in your apartment and then your mother rings the doorbell? It's the kind of problem only Imaizumi would have to face. But his degenerate life in that tiny apartment had to end someday…only to restart in a much larger apartment! And with all that extra space, there's plenty of room for a new girl to join his expanding harem!
