I'm having a hard time deciding which of the two to get. I'm thinking of having whichever be a sweet character, so I like the sweetheart color but the Anyu doesn't come in sweetheart yet. Then again I really like the storm Anyu but I'd probably have to change the idea for the character if I go with the storm Anyu. Any suggestions?

I'd say go with whichever you feel more drawn to, since all options are very good ones. :D You said you wanted a sweet character, so a SH pet would obviously be very fitting. You could always wait until they release the Anyu, but I have a feeling that it will take quite some time since they usually release sweethearts during Survival. Thankfully the sweetheart potions are only 100 candy hearts, so it's relatively easy to get enough hearts to purchase a new potion in case you want to change the pet color later so there's always the option to make the pet a sweetheart chai now until the SH anyu is released, if it feels more appealing.
(As for the storm pet, if you don't have enough room for two new pets, you could consider if any of your already existing pets might fit the color/species ? Good luck! ❤️
Thank you so much for giving me an opinion. :) You've totally convinced me to get a Chai. I think it'll fit more with the character I am trying to go for, and as you mentioned I could always change it to an Anyu.
I was thinking the same thing for the storm pet, maybe changing Katessyn into storm or waiting to see what other storm pets they release.
Thanks again ;)
In my opinion, if you love the Storm Anyu, then choose it and let it have a sweet character - after all there's no restriction that a sweet character has to look sweet as well. My Tyr for example is a Graveyard Legeica but based on his character he's probably one of the nicest and most noble guys I have on my account. :)
The same goes for Rosaly my bloodred Legeica, Hahaha! I went with bloodred to make her a bit mysterious and shy but still nice. Honestly, all my characters/pets are nice because that's just how I am. Hahaha!
I chose the Chai already but it'll be a while before I can make it sweetheart so hopefully a storm one will come out by then because I really love the storm pets. The way my brain works is if I go with storm the only thing that would change is i'd make a more serious pet, still nice, but serious.
Thanks for your opinion, I hope I can make up my mind. Hahaha! :)
the sweetheart Chai is cute but really its up to you what one you want as it will be you who makes the finale chose as well as having to wright the story for them.
You're right, it is ultimately up to me. I was just having a hard time deciding.
