No. This is not Yuri!!! On Ice.
I have seen so many comparisons and expectations online about SLS contrasting it with YOI. Believe me, it has its own merits that it managed to present its own identity as ice skating sports anime. From the premise, it's a group sports, thus, it heightens more spirit and soul as sports genre.
There is an immense difference in the plot narrative, however, you can sense the quick phasing of the competition to the extent that it needed to compromise most of the skating performances. For a 12-episode anime, it lacked so much in sports action. Hence, in compensation, it focused on another domain which is characterization.
Since it is group sports, the names and faces to be remembered doubled. Nonetheless, most of the characters are written good. You can at least distinguish which is which. The characterization is far from perfect also, there is no really astounding with these boys. Nothing remarkable. They seemed like normal high school teens flared with their courage to win, and they have different cores clashing, and whoever wins will be the best. That's it, nothing more.
But things get better until the end, I was a bit sleeping from the early episodes but when the Grand Prix Final ticked, you just can't leave the screen. The last episodes finally manifested what a sports genre should be-- the thrill, excitement, and nerve-wracking moments. The questions of, "Will they gonna make it?" "Can they actually beat them as underdogs?". As I questioned myself about this, it finally hit me that it is actually getting good for a sports genre. Maybe a bit late, but at least, it managed to embody the expectations that I have.
I have to admit, it is mediocre but you will remember the characters for sure. It is best to watch when you thirst for good-looking hot boys, I'm not kidding because they really put much budget to them (lol)
