I, Shark-chan, ``A mysterious life form that came from beyond the ocean, farther than the universe! ”

There was a lone \"shark\" on the roof of my high school. No, to be precise, it was a girl in a shark costume. She called herself \"Shark-chan\" and suddenly appeared. Who exactly is she? And why is she wearing a shark suit? \"Well, this is a piece of cake! Shark-chan confidently declares, \"This is a piece of cake! But despite her words, she was shivering in a corner on the rooftop. The reason for this was the black-clad combatants standing in front of her. What is your purpose, Shark-chan?\" The leader of the fighters asked. Shark-chan managed to muster up some bravado. Shark-chan managed to bluster his way through the situation. How do you mean world domination?\" another fighter questioned. Shark-chan was so flustered by the sudden barrage of questions that she couldn\'t help but let her true feelings out. I\'m actually just cosplaying in this getup...I like Earth culture and I wanted to make friends...\" The combatants instantly froze in place and then burst out laughing. They, too, were aliens from outer space, interested in Earth\'s culture. The combatants\' true purpose was to study Earth\'s cosplay culture. Shark, you were an alien too? Then let\'s go to a cosplay event together!\" Really? Yay!\" And so, Shark Girl and her combatants went on a rampage at the cosplay event. Their slapstick gag comedy continued. In the end, Shark Girl and the fighters formed a true friendship and spent their days enjoying Earth\'s culture together. And her habitual saying, \"Hmm, this is a piece of cake! gradually changed to \"Together, everything is a piece of cake! gradually turned into \"Together, everything is a piece of cake! Friendship sometimes comes in unexpected ways. As if to prove this point, the encounter between Shark and the fighters quietly blossomed on the roof of the school.
