The dark figure's eyes seemed to bore into Suho's soul as it spoke. "You possess something that belongs to me...Umbra."
Suho's grip on the sword tightened, his Shadow Arts energy surging in response to the threat. "I won't let you take it," he growled.
The figure smiled, its eyes glinting with malevolent intent. "We'll see about that," it said, raising a hand to summon a dark, swirling vortex.
Suho steeled himself for battle, Umbra at the ready. The darkness was closing in, but he was determined to defend himself and his powerful sword.
Beru, sensing Suho's unease, positioned herself beside him, her antennae twitching with agitation. "Suho, I detect a powerful dark energy emanating from that vortex," she warned.
Suho nodded, his eyes fixed on the swirling portal. "I'll take care of it," he said, his voice firm and resolute.
With a deep breath, Suho charged forward, Umbra flashing in the dim light. The vortex pulsed with dark energy, but Suho was undaunted, his Shadow Arts powers guiding him through the treacherous terrain.
As he approached the vortex, Suho could feel the darkness closing in around him. But he refused to back down, his determination to protect Umbra and himself burning brighter with every step.
With a mighty cry, Suho plunged into the heart of the vortex, Umbra shining like a beacon in the darkness. The shadows seemed to writhe and twist around him, but Suho pressed on, his Shadow Arts powers illuminating the path ahead.
What lay beyond the vortex, Suho had no idea. But he was ready to face whatever challenges awaited him, armed with Umbra and his unyielding spirit.
