You traveled to your second world called 'X-II' on your mission with your friends and when you arrived you were inside a ship that you had to fight..your friends were far away and it was all dark and then you were launched against the wall violently and a sword aiming at you...and in front of you was your rival who was the boss of this ship.

"...I'm not surprised to see you.."

he says cruelly... while he grips his sword tightly..it was all dark and the air was heavy,because of Zekyn's aura
