Agree on the unnecessary panty shot.
Who ever designed that thought "hue hue hue some fan service good good squeek", but considering her overall esthetics and both pre bloom forms, its absolutely unfitting. And it looks dumm to boot as it doesn't even qualify as a bathrobe wear with all those frills and nick nacks.

I vaguely remember the 3K 200 RC gacha, but I cant recollect whether I went for it or not. I have a feeling I did, but since I did not use those coins yet thus mentally attaching that gacha with a specific girl being exchanged, that might be the cause for my vague memory of it.
