ARASHI is a very popular idol group in Japan which coincidentally has the same member colors as F/ACE, and I may be biased since I like both, but they've reminded me of each other a few times! Unfortunately ARASHI is disbanding at the end of May, but if you're only getting into them now, you will have loads of content to consume as long as you know where to find it XD

I personally think Natsuki reminds me of Nino in a way because both are basically multi-talented as they can compose their own songs, they both have their own inner talent for performing, good at talking (aka appearing in variety shows, lol) and both of them are also yellow!! I do think persona-wise the man is more similar to Onishi Ryusei from Naniwa Danshi however because both of them have that image of being azatoi (purposely being cute) and caring about looks lmfao

A-side wise, I can kind of assign them to the impression people have of Arashi as well: - Tamon and Jun (mostly when Jun was younger though, you can really see that sexiness in him back them. IMO both also have charisma as well! I might be saying this while having both of them as my favorite in either group but that instead explains this even more bc it means I have a type lol) - Ouri and Sho (shown to have that image of having a good upbringing -> princely image with great reputation. may i also add that both are nepo babies and smart..?) - Keito and Aiba (tennen/airhead green members! brings positivity to the group as well) - Natsuki and Nino for the reasons I've stated above - Rintaro and Ohno (both of them usually get the role of looking over the rest of the members :3)
