for one of the stream events you need to use nirnroot you will see alice with i think is a bra with a cat face in the middle where you can see her tits and for the swimsuit i just really got it random.Can you tell me how you trigger that quest? I'm still checking the stream from time to time, other than calling me out for not wanking, the school uniform and getting bored, I've not seen any other event. BTW, I'm 100/100/1 and >50 on everything but AP for stats.
I would like to tell you how to get the swimsuit but literally no idea
