Why not? Yuno onee-chan was amazing, and a lot of fun to play with...oh, but I can't play with her anymore... [He frowns slightly at that for a second, but then he's smiling again.]

But I'm happy that I met you, Homura onee-chan. You can do things that even Yuno onee-chan couldn't do, and it's been a lot of fun playing with you too! [Even if it really isn't a good thing to be compared to Yuno, Reisuke thinks that you're kinda cool, Homura.]
