Yeah, I see Negi have hold many times about Nino and loliNako. Don't know he's teasing us or there are hints.
+ Nino recognized him when see photo again
+ One of 2 quints who use right hand in photo (with Yotsuba)
+ And some nostalgias in this trip.
Quite interesting. If she's real loliNako it's would be 2nd bomb since her confession in chapters 59-60
