I really loved this idea!! Not just Nino going back in time but that Arashi has managed to find each other at several points across time ;_______;

I like the mention of Nino and the helmets from his Shiyagare segment as a potential catalyst for time travel, too funny!

And I adored Nino's interaction with the Jun from another time, the differences and the similarities of each of them. And almost as much as I loved the Matsumiya, the Aimiya friendship across time was wonderful too!!

Some really lovely descriptions and a fun concept, well done!! :) :)
