It turned out that he callmentioned the name of a user.

or

It turned out that he called out the name of a user.

She often visits Japanese vTubers’ live streams and cracks people up.

Not only is the name funny, but she also she has a unique sense of humor, and her comments are hilarious, too.

She understands Japanese, and her comments are Japanesewritten in Romaji.

This video is about when she visited famous vTuber Himono Kanbutsu’s live stream.

It’s hilarious, so Himono botheredtook the time to make this video.

I have talked to her on Twitter once, and she replied.

Another funny thing is that she keeps claiming that she is seiso regardless ofdespite her hilariously opposite of seiso name.

ハハハ！

I have talked to her on Twitter once, and she replied.

The her here is presumably "Super Sexy Boin Boin". I don't know the gender of Himono so not sure if "her" could refer to them instaead.
Without putting the whole name you could say "I have talked to "Super Sexy" on twitter.
Also you could say "I have sent her a message on twitter once and she replied" using "talked to " implies a conversation including a reply.

Another funny thing is that she keeps claiming that she is "seiso" regardless of her hilariousloutrageous behaviour being the very opposite of "seiso name."

Put "seiso" in quotes as it is not a word know by non-Japanese speakers
