It's a huge horse.
The horses around this area are all generally massive for the sake of crunching along even in the snow.
It feels like they're an even larger size than even the horses of the Ban'ei horse racing. [1]
It seems their speed isn't all that great, but they have physical strength and they're fine running for a full day as well.
It seems like there are many horses that are like monsters in this world.
For the time being, I'll give it the name Matsukaze I guess.
