Hey y'all!! I need your help, anime lovers! I've got to do a project for my career and it's about an unknown animation studio but I'm not really into those. So, I thought, who'd be better to help me that people who really love this stuff?! So, if you could help me and tell me some unknown studios that I can search about, I'd be extremely happy and grateful!!!! Love you all, pals!!
