At first I thought you were talking about Shishiro Botan (given the context) and was confused.
Then I remembered the other best girl Botan. The one that actually won in a manga.
As for the chapter, he did the thing he had to do : out himself as her manager. That was the eaqy and simple solution.
Also people, toxic retards exists, but keep in mind they are a minority. Fubuki get less than 600 dislikes (compared to 20k+ likes) when she collabs with men, and Towa just went past 500k subs. A few creeps is nothing. FBK also demonstrated it a few month ago.
Tbh the real problem in Japan is 2ch. These guys are just plain dangerous.
