Kisame grabbed Samehada and swung it at Mirai.
Clang!
Mirai pulled out the Sword of the Thunder God from his system space and effortlessly blocked Kisame's great sword, Samehada.
"Hah!"
Seeing how little regard Mirai had for him, Kisame silently grew angry. His empty left hand suddenly gripped the hilt, instantly increasing his strength.
Yet Mirai remained completely unmoved.

Kisame stopped him from coming over to help.
Just then, the Sword of the Thunder God
