ut i want you guys to remember this and note this, each rider who use Seiken Swordriver has a different sword with different name. First is Kamen Rider Saber's sword, Kaenken Rekka.

Second is Kamen Rider Blaze's sword, Suiseiken Nagare.

The transformation announcement is going to be too long, TOO LONG! i mean it, i wont be able to memorize it 😂. It's because the Wonder Ride Books has a long voice announcement which made the henshin is too long.
