kagami was badly injured being attacked by the gattack zecter merely because the zecter thinks that kagami wasn't the qualified person to use em

in this week release, kagami will become gattack.the reason why the zecter choose kagami is still unclear but some fans suggesting that kagami actually begs the zecter so that he could save the boy from the factory and perhaps being controlled by the zecter even after that might be the risk he would face

and the origin of kamishiro tsurugi aka scorpioworm still unclear.some of the fans suggested that he died during the worm attack against his sister n the worm mimic him instead. but how he become a rider n y sasword zecter pick em still unclear

in order to obtain the power of gattack the user must actually die!!! (my opinion la) so that's what happen to kagami when he tried to save the boy at the factory. The boy whom was actually a worm (agak dah) killed him during their encounter. That is when gattack heard his cry that it decided to revive kagami. it was then when mishima put the belt to kagami enabling him to henshin into gattack. Tendou realising kagami's utmost revenge to the worm boy let gattack do the killing himself without interfering.

it seems that gattack has 2 choice of finishing moves 1 using his dual blade or 2 a flying rider kick which contradict kabuto full roundhouse rider kick. Next ep...sasword(worm form) vs kabuto n gattack vs worm!!!
