Saru shonen was doing paperwork when the hell butterfly had arrived once the message came he grabbed a gray suitcase and left for the senkaimon automatically. once saru shonen makes it to the senkaimon saru says" Damn why the hell are they swarming the human world someone or something must be behind this. After he walks through the senkaimon the cleaner appears and starts chasing saru, now saru is running trying to avoid the cleaner but the cleaner some how speeds up, now saru has to use his shikai just to boost his speed. tear out their soul tsubasa no akuma with that he moves so fast that the cleaner cannot keep up and winds up making it to the world of the living. Saru shonen says"damn that was way too close for comfort he sees the damage the hollows are doing right now with his eyes wide at the site of the destruction.
As he snaps out of it he flies straight down and yells" Fukai no kōte Kaminari asshuku making the water as sharp as his blade chopping 4 hollows straight down the middle. Afterward a hollow tries to hit him with his tail but saru blocks and cuts it's tail off. next he chopped stabs him right through his mask making his body. Another one flies at saru trying desperately to lay a hand on him to no avail and saru chops him in 5 pieces making his body disintegrate. The next hollow lunges at him with a sword like hand, but saru easily dodges it and cuts off his arm then saru stabs him through his mask like the other 1 making his body disintegrate All the hollows started attacking him but he mows them down 1 by 1 killing them all, but then a menos grande shows up charging a cero. Saru tries to make it to him before he can fire it but to no avail. The menos grande fires the cero and it hits him he dodged part of it so he sustained minimal damage but damn it hurt and felt like it was serious.
The cero was strong he had to finish this hollow quickly. Saru comes up with an idea to finish this menos once and for all. he grabs something out of the gray suitcase and throws it saying" here die by the power of the Suu~ifutoraion wa hoshi o kurasshu. The menos fires a cero at it but because it absorbs attacks and reatsu it just absorbed the blast. It hits the menos grande and blows up completely eviscerating it. Afterward he goes back to the soul society to give his report to the head captain. When he makes it to the soul society he tells the head captain about the how the swarm was caused by a menos and everything that happened but passes out do to his injuries.
