I'd take her to an arcade and play Tetris TGM in VS mode. I'd beat her, but not by too much (we'll have to go on a second date if she wants to try and beat me). Then we'd get yakiniku and go to a karaoke bar, before I walk her home once we start to get tired.
As far as desirable traits, I'm tall, skinny and a pretty good raconteur. I'm also a trained musician, so that could be a point of connection. Personality-wise, I'm initially quite cold but warm up to certain people; while it's not an exact match, she likes kuuderes and I'm quite close to that. The only hindrance would be that I don't know enough about some of her interests (EnSta, non-vtuber idols) to discuss them.
