I started watching Future Diary mainly because of Yuno Gaisai

I first got into anime with the nico nico nii meme. My friend showed it to me and I then proceeded to watch all of Love Live to one up him on the Nico meme. I didn't expect to like anime but now It's the main thing I watch

probably Mai from Rascal Does Not Dream of Bunny Girl Senpai

honestly thought it was an ecchi show cause of preview image and title

i was suprised it was actually good

thts it

I wanted to see all the hype around Kira since I was a hard Lelouch fan before and he was being compared to Kira in almost every comment I saw.
It was a great idea, I loved Death Note.

dazai from bungou stray dogs. had zero clue what it was about but when my friend showed him, i Had to check it out

Mayo Chiki
Wanted to watch this cause of Subaru but it was so bad.

Violet Evergarden
Watched it because of Violet and it was worth the watch.

love live because nozomi, keijo because nozomi, monster musume because of miia, priconne because kyaru

tl;dr: hot

kanna from dragon maid.

Watching this because Celia is cute
Celiasensei no Wakuwaku Magical Kyoushitsu

Dio from Jojo, idk. He just seems to exude chadliness, and has a villainy aura every time I look at him. Oh, and also the memes. They're ridiculous af

Promare because Lio doesn't look like the typical shounen protagonist and I had heard it had some gay innuendo.

She smol

Jahysama wa Kujikenai

I decide to watch a ton of animes because of one character, because one way I find out about stuff is mudae rolls and I only look into it if the character picture is cute. (It's usually not an anime though. Or an isekai I don't care about.)

But I don't really remember those characters, so aside from those...
I first watched gochiusa after seeing tons of fanart of chino.
Eromanga sensei for sagiri. Though this one was also due to mudae roll.
OneRoom for Natsuki. I knew about this one, but I didn't consider watching it until my friend told me about her existing.

I watched Kakegurui only because of Yumeko

Yup,
"In Another World With My Smartphone"
For Yumina Urnea Belfast

makoto from The Idol Master. saw her on a tweet about characters named makoto being good and instantly went "oh who's THAT"

her character design immediately sold me on a show I didn't think I'd end up watching

I saw fan art of holo once and decided to watch the first season of the anime and now Im reading the light novel lol

I watched Black Lagoon for Revy and then I realized not only is Revy so much cooler than I thought she would be but the entire show itself was a hell of a ride.

Nezuko from Demon Slayer.

Love Chunibyo Other Delusions

because of that one clip where Rikka gets hit with paper and goes "oW"

One Punch Man

i've decided to watch it because i liked the "badass" vibe that Garou gave

*note : it wasn't worth watching at all

rin tohsaka

Yes. Kiritsugu Emiya

Kanna from Dragon Maid and
Chika from Kaguya-Sama Love is War

this character got me to watch one of my favorite anime f all time https://anilist.co/character/4163/Rin-Kokonoe

Darling in the Franxx

Everyone was like "Dude Zero Two is the best waifu" "S tier waifu"
Not worth it i didn't like the anime or Zero Two

Gilgamesh looked hot so i watched Fate

I started watching ReZero after seeing Rem
Started watching Konosuba after seeing Aqua
Started watching Shield Hero after seeing Raphtalia

Quintuplets mainly because of Nino. Though in the first season was the worst quintuplet imo, in the second one she skyrocketed to the first position with Miku, so hey, nice idea
