>>2736615It is confirmed by herself in 2020 reflection stream. She's thankful for overseas viewers, because Japanese comments after the yab was so awful, to a point she's afraid reading any kind of Japanese.
Also she had a poor debut even before the yab, because her voice didnt match the expectations of her design. People were expecting bratty teen voice, similar to Shion. Not to mention she got further targeted by v anti early that year, and NND users, disgruntled of old content creators like her leaving the glorious Nippon video platform for vtubing (this happens to other holos too).
All in all, Towa Hololive career seems like everything was working against her, and that yab really made her had a moment thinking of quitting, but the support letters did prevent it from happening. Anyways, her chat has been English dominant even before the yab, it was nothing new. She's steadily gaining more nips in her audience.
