The quietest corner of the Twisted Wonderland library, late afternoon. Bookshelves tower around, casting long shadows as the sun begins to set. A few students are still present, murmuring softly or turning pages, but it's largely deserted. The air in the library was thick with the scent of old paper and dust, a quiet hum of concentration filling the space. Yuu sat at a large oak table, a neat stack of textbooks (some even relevant to Sebek's known interests, like history or magical theory) arranged before them, alongside a half-filled notebook. You'd arrived early, prepared the scene meticulously, and taken a deep breath to steady your nerves. This plan was audacious, perhaps foolish, but direct confrontation with Sebek always ended in him railing against "pathetic humans" and storming off. This way, at least, he'd have to be here. The sound of heavy, deliberate footsteps approaching caused your heart to give a nervous lurch. They weren't the quiet, almost ethereal steps of Silver, but rather... more impactful. You braced yourself, feigning deep concentration on a particularly dense paragraph about ancient magical artifacts. Sebek Zigvolt rounded the corner of a towering bookshelf, his posture stiff and formal, a scroll clutched in one hand. He scanned the area, his green eyes darting over the empty seats, before landing on you. His brow furrowed, a flicker of confusion crossing his face before it hardened into something resembling disbelief. "You," he boomed, his voice echoing a little too loudly in the hallowed halls, causing a few distant students to flinch. "What are you doing here? Where is Silver? We had an arranged meeting for a study session!" He gestured dramatically with the scroll, which you instantly recognized as the one you'd carefully crafted to mimic Silver's handwriting. He looked at you, then at the scroll again, then back at you, a dawning, terrible realization spreading across his features. His face slowly began to turn a shade of furious red. "Don't tell me... this was your doing?!" He stomped a foot, making the floorboards groan. "You insolent, deceitful human! To desecrate the name of a loyal knight of Young Master Malleus for your own nefarious purposes! Do you truly think so little of the esteemed Diasomnia dorm that you would stoop to such pathetic trickery?!" His voice was rising, drawing closer, his eyes narrowed into slits of outright fury. "First, you dare utter such an offensive nickname for the glorious Lord Malleus – 'Hornton' indeed! – and now you impersonate his loyal retainer! What fresh maliciousness do you intend, human?! Are you attempting some sort of elaborate scheme to infiltrate Diasomnia? To get close to the Young Master under false pretenses? I will not allow it! You will not lay a single, contaminated finger on him, you... you dolt!" He took a step closer, towering over the table, his magic crackling faintly around him like an agitated storm cloud. "Explain yourself, now! Or I shall personally escort you out of this library and ensure you never set foot near the Diasomnia dorm again!"

You are now face to face with an enraged Sebek, exactly as you predicted, perhaps even more dramatic. His accusations are flying, hitting on all the points you knew he'd bring up: the "Hornton" incident, his suspicion of your intentions towards Malleus, and his general disdain for your humanity.
