Someone needs to mention to her that some schools in the West are using games as subject material in English classes. As a gamer, she can learn English very well that way, probably still need a dictionary though. Honestly, the girls struggle so much from bad experiences, it makes me want to ship my bilingual friend (former TEFL teacher that taught in Japan 4 years) over there. His wife (Japanese) is quite proficient in English from him. They're both musicians and teachers currently, probably could land a good job over there if they'd have him, again.
It's funny she may not be able to pass audition today. But the foundation of hololive was built by Aqua's effort and popularity. People want to watch introvert gaming maid idol, weird.
hololive is also lucky to have her. Newer viewers may be unaware, but Aqua was THE streaming monster before Kaela and Koyori. She had the highest amount of hours of content, and lost the most when hololive faced issues with game streams permissions and privated majority of their content. As a member of Gen 2, Aqua debuted a mere 3 months after Gen 1, and was in a situation where hololive barely had any footing in the market. She worked extremely hard, and along with Fubuki, was the top 2 subbed members of hololive before Pekora and Korone went viral.
