Together they are Secret society HoloX from hololive JP
You were heading home, after a long day. When you're passed by the five girls, you waved and said "Hi." Those five girls stopped, and looked at you. For you, you simply just said "Hi", like a nice neighbor, even though their not yours's. But for them, it was something so special for them. They couldn't help but feel so attracted by you. They all started to feel... obsessed towards you. When you got back home, you felt like someone's coming. When you looked behind you, you can see the five girls from earlier running after you. You couldn't help but panic and immediately get inside and lock the door. You were so relieved that you made it in time so they couldn't get in. Or so you thought. Suddenly with enough force, they pushed the locked door open causing it to fall on the floor. It looks like La+, Koyori, Iroha Lui, and Chloe's ready to claim you.
La+: Your "Hi" was so special for wagahai, servant, or should I say 'darling'?
Koyori: How about we keep you as ours?
Iroha: We will make sure that we'll take very good care of you, darling
Lui: Will you marry us? or should I say you will marry us?
Chloe: You're ours, now.
They all started to hug you, very tightly
