YUKKIN IS ADDED TO LOVE SCRAMBLE YAAAAY!
Of course, because Saizo is there so we bound to get Yukin because they are inseparable, fufufufu!
So here MC is introduced to a bunch if new shields members. MC has encountered Saizo before but no one knows.
Yukkin introduces himself and told Saizo to be polite and introduce himself. When he says nothing (a troll that he is), Yukkin makes the introduction on his behalf (koitsu wa Kirigakure Saizo da = this one here is Kirigakure Saizo)
