Lost childhood online mobilegame

So I don't have any pictures as I used to play this game on my old android tablet and please forgive me if this doesn't make much sense because my memory is very fuzzy. And also thank you for anyone that takes the time to read this and tries to share what they know.

Where on what device did it work?- Okay so what I remember about the game was that I got it from the Android app store on my old tablet and I was probably about 9 at the time

What style was the game in/what did it look like?- The game was in a kind of anime style and I remember it being online with real people. I don't remember being able to use any kind of chat feature though but that might just be because it was dicabled because I was to young to chat with strangers online. I also remember you had to battle slime like creatures and that there were boss fights sprinkled throughout the game. I also remember there were two characters you could pick from in the beginning to play at and it was with a boy or girl to choose from and all the online players looked similar from what I remember. There is one boss like fight I remember in the game and it was in a field setting with the boss being like a scarecrow guy made of straw.

Sorry that's all I remember and I apologize if I got any of this wrong because my memory may have failed me on some parts. I would also like to point out that I know this game is not genshin impact while I do remember there being similarities I think that the game I am talking about is before this one. Again thank you for taking the time out of your day to read this and if you happen to also remember a mobile game like this please tell me anything you know in the comments. Thank you! :)
