Its a virus,i swear!! It only takes up storage and harms ur device,DONT GET IT! 
I have got it and alot of gacha mods do that so its normal...I don't know why your saying this bs..So just stop... And I not saying your stupid for saying this some people can get hacked... So stop saying bs..
I tried installing it a long time ago. There was simply no virus a long time ago yet. But a year ago I saw a notification from Google Playstore that this Gacha mod has virus. But now I think it’s safe to play with it today. (Probablly)
It does that but it doesn't mean it's a virus it's it doesn't do anything get actual proof before posting and gachatubers have already noticed this and if it actually done something they would convince people not to get it.
Its only harmful if the creator didn't say it was on here because it would most likely be a scam but creator did say it's on here so it's not ♡
It'll do that as a warning, a believe a lot of things on itch are not viruses, i've downloaded thousands of mods in the past on here and I've gotten the same warning, it won't do anything to the device itself
Im not really entirely sure but, based on the Gacha Mods i use, it always says that, and based on the mods i used to have, There's no such thing as a virus but it can be possible, im not sure.
