A pair of katanas that Samurai Soul is holding
When Kairi Sanjou transforms with Musashi into Samurai Soul, he wields a pair of katanas as primary weapons. He can use them to perform a cut-through attack called "Lightning Blade".
Fanon Description by Caramelangel714[]
Samurai Soul's katanas are given with a precise upgrade and title, known as Blue Asteroids (青い小 Aoishouwa?).
Etymology[]
Shouwa (小?) is shortened for Shouwakusei (小惑星?), translates to "asteroid". This can avoid creating a long term.
