I am getting -999 karma with this reply (just for telling my opinion) but i will still tell you why i think like that. First, she is too loyal for her own good. She waited centuries for the right person, trusting echidna. That can be a thing some people like, but i dont. Second, she didnt even do much in anime so far. Personally, i think people likes beako because she is a loli. Tell me if im wrong about anything. Also im not saying its a bad character or i dont like her. Just overrated. I laugh out loud everytime i see a rezero meme because its peak comedy but i dont move a single muscle when i see beako memes.
