Just to be sure, NTC is the same rink as the Toyota center? I'd imagined there was only one rink at Chuukyou, and was surprised to hear of the existence of the Rainbow rink.
It's getting confusing for me too!
As far as I know (mind you, I may be wrong!)
Toyota Sports Center in Toyota city does not have an ice rink. (But
Toyota Center in LA does, right?) I think Shoma uses the rinks in Chukyo univ mainly now but not sure.
NTC (National Training Center) for figure skaters is the same rink as
Aurora rink in Chukyo university.
NSC (Nagoya Sports Center, also known as Osu rink) in Nagoya was/is his home rink for long.
Rainbow rink, right next to Aurora rink in Chukyo univ was built for Mao a decade or so ago and it's a small rink, but with huge mirrors, great for choreo. I'm not sure if non-students can use it or not. There are quite a few ice rinks in/near Nagoya, so Shoma can always rent other rinks privately too, and it's probably better to ask Shoma's dedicated fans about his main rink. I hear that skaters in/near Nagoya often use more than one rinks, and I can never tell which rinks are their main ones.
And my bad, my clock for Sota kinda stopped once, still recalling him as a high school student and I always forget that he's also a Chukyo univ student now.
Eh, does Kazuki like other meals beyond ramen? I've just had this vision of myself hunting for suitable presents if Kazuki ever participated in a competition I could go to, and ramen-themed stuff is practically impossible to find here in central Europe...
He said he's open to any food, as in バカ舌! That said, strawberry or otter or ...dunno. I do remember Tomono-kun once said eating Tsuna-mayo onigiri was just out of convenience when he's busy and not particularly his favorite, though. I'm sure someone else has a better idea.
Saw this post of Kazuki and another skater friend attending "An American In Paris" show

It's like a parody to #パリのアメリカ人. Oh well, this Osaka trait will never wear off.
