Peasuke Soramame, known as Piisuke, is Arale Norimaki and Akane Kimidori's classmate and Taro Soramame's younger brother. He constantly wears an animal hat, drawing criticism from Taro. Insecurity and sensitivity about his short stature define his character, a concern persisting into adulthood. Despite a timid and wimpy demeanor, he often acts as the most reasonable voice among his friends. He first appears on Arale's initial school day, joining her friend circle after witnessing her strength. He develops a romantic interest in the taller Hiyoko. Their relationship faces challenges, including Peasuke accidentally urinating on himself during an encounter with a school gang leader, causing Hiyoko to temporarily reject him. They eventually marry and have a son named Poosuke Soramame a decade after the series' conclusion. Peasuke participates in adventures with Arale and Penguin Village residents. He uses Senbei Norimaki's Future Camera, learning his height remains unchanged in ten years. He joins Senbei and Arale using the Time Slipper to travel to the prehistoric era, obtaining a dinosaur egg that hatches into Gatchan. In the film *Dr. Slump & Arale-chan: Hoyoyo! The Secret of Nanaba Castle*, he joins Arale and friends on a quest to reclaim the stolen "Eye of Rainbow" treasure from the antagonist Bisna, who seeks to revive a devil and the Nanaba Kingdom. Peasuke appears briefly in the *Dragon Ball* timeline. During the Red Ribbon Army Saga, the manga shows him leaving Penguin Village Middle School for vacation, while the anime depicts him at the Coffee Pot informing Akane about homework. He makes cameos in *Dragon Ball Heroes: Victory Mission* during a tournament and in *Dragon Ball Super* Episode 69 when Arale crashes into the Coffee Pot. In the 1997 *Dr. Slump* remake, his character design remains consistent, with his animal hat changing from white to gray. A live-action G.U. commercial features an actor portraying Peasuke alongside Akane and Taro, observing Arale outside the Coffee Pot. Peasuke habitually requests autographs. His birthdate within the *Dragon Ball* universe is September 1st, Age 732.
