It seems cerebro has found himself shrunken and faces off against an unaware koromarus butt boss fight here is the story that goes along with this!

Cerebro has just recently joined the S.E.E.S organization (that stands for Specialized Extracurricular Execution Squad), and he and the rest of his crew are heading on his first mission. His fellow crew members have a lot more experience, having defeated a powerful god known as Nyx just a few months ago. Cerebro, on the other hand, is very cocky and hotheaded; like if a shadow blocks the S.E.E.S path, Cerebro instantly runs out and kills the shadow before anyone else. He has a very powerful persona named Cranium, but at one point, the S.E.E.S find themselves trapped in a strange room filled with red carpet. In front of them, there’s a giant bush with a tiny blue door that Koromaru (the Shiba Inu dog) wouldn’t even be able to fit his head through. The S.E.E.S found themselves stuck until Cerebro found a strange blue bottle sitting on a table. He was very thirsty and thought the bottle was water, so he began to guzzle it. The rest of the S.E.E.S weren’t even looking at Cerebro as he thinks in his head, “That was some strange-tasting water… and why do I feel so weird?” Then Cerebro blacks out for a second as he shrinks down to almost microscopic size, and meanwhile, no one even noticed. When Cerebro finally regains consciousness after a few seconds, he finds himself in a strange new world (well, it’s the same place he’s in, but it feels different to him at this size). The red carpet that was under his paws a second ago now has the little fibers looming above him. “What is this place? Why do the trees—or I assume they’re trees—look like that?” Cerebro thinks. Meanwhile, high above the carpet fibers, the rest of the S.E.E.S are trying to figure out what to do when one member known as Junpei notices the bottles and exclaims, “Guys, get over here! Look what I found!” Then the robotic android of the group, known as Aigis, does a scan of the bottles and says, “These are shrinking potions; they shrink the user who drinks one until they find a growth antidote.” That’s when the S.E.E.S notice an empty bottle dropped on the floor with a couple of small blue drops trickling out of it, and then they notice that Cerebro is missing. That’s when Aigis says, “Please, no one move! Cerebro must be shrunken somewhere in the carpet fibers. I will use my built-in microscope to find him.” Then Aigis’s hand turns into a microscope, and she proceeds to look for Cerebro. Meanwhile, since Koromaru is just a dog, he doesn’t understand to stay still, so Junpei tells him to sit. Koromaru, being the good boy he is, proceeds to sit. But meanwhile, underneath the carpet fibers, Cerebro is still trying to figure out where he is. At the same time, Koromaru begins to sit down, so all of a sudden, Cerebro sees a giant fluffy object slowly getting closer to him (since when you’re small, everything moves in slow motion). Cerebro thinks that Koromaru's tail is a giant shadow, since Cerebro doesn’t realize he is tiny. He proceeds to pull out his sword and says, “Persona!” and prepares for battle. He uses Myriad Truths (yes, Cerebro's persona is so powerful that it knows Myriad Truths), but even Myriad Truths, at Cerebro's tiny size, barely does anything to Koromaru; he doesn’t even feel it. Koromaru’s butt gets closer and closer to Cerebro as he gets frustrated while trying to repeatedly attack Koromaru's rump. “No! Why isn’t this working? This giant shadow that looks a lot like Koromaru's rump is about to crush me!” Cerebro says as now the carpet fibers begin to crinkle back. Koromaru's rump is now just above Cerebro, and then “fwomp!” Koromaru is now fully sat down with Cerebro under his rump. And that’s where the story ends for now, on a major cliffhanger. To be continued????
