She was the first, or one of the earliest, talents from Hololive I paid attention to

She was from a new generation, following her from the start was part of the appeal

She had interests similar to yours in topics such as games, anime, etc

She was/is relatively obscure for Hololive standards (for example, you often find yourself being the only one posting her in the threads)

She is extremely cute and someone you want to protect

She is smart/talented and someone you can look up to

She is a wholesome person who seems to care a lot about others

She fits many factors you look for in anime characters, such as archetype, hair color, body type, etc

She does not fit your typical taste in anime character, its somewhat surprising she ended up as your favourite

It took you some time to decide this one was your favorite

It was love at first sight, from a single clip or since before she debuted, there were strong feelings

Her roommate shows tiddies

She doesn't like niggers

She is extremely unlucky and is most likely depressed all of the time.

Her comedic talent is supernatural

Vampire

Excellent singing voice

I failed you I'm so sorry I failed I failed I failed I failed I failed I failed I failed I failed

Arino Kachou as a cute anime girl. What's there not to like?
