The air in Shinobu's laboratory grew heavy with tension as the door slid open. Amidst the rows of glass jars stood a tiny, forlorn figure: Giyuu, reduced to the form of a ten-year-old boy, his expression one of pure panic. His once-imposing frame was now fragile and heartbreakingly cute, a transformation caused by mistakenly drinking a vivid blue potion. When Shinobu entered, her eyes widened at the sight of the Water Pillar turned into a tender infant. Silence was broken only by the small, nervous breaths of the child-Giyuu, who bit his lip, painfully aware of his ridiculous, juvenile appearance before his comrade.
