Amidst the tension, a young villager named Hana stepped forward, her determination overcoming the fear that gripped the others. 

"We won't let you harm us any further. You just ruin our sacred traditions." 

she declared, rallying the villagers behind her.

Kigai's eyes narrowed, a sinister grin playing on his lips. 

"You're all insignificant in the grand scheme of things," he sneered. 

"Give me the flute, or face the consequences."

Hana, fueled by courage, refused to back down. 

"We'll protect our heritage. You won't break us."

The standoff intensified as the villagers braced themselves for an unforeseen battle against a force they couldn't comprehend. The air crackled with a blend of defiance and fear, setting the stage for the unfolding struggle between Kigai and the resilient people of Shinpi.

Jin stepped forward, his presence commanding attention. 

"Step back, everyone. Let me handle this," 

he urged the villagers, a determined look in his eyes.

Kigai remained eerily still, his demand for the flute echoing through the tense air. The villagers watched with bated breath, their trust now placed in Jin.

The remaining elders, their fear mingling with curiosity, questioned Kigai's motives. 

"Why do you need the flute? What darkness are you bringing upon us?" they implored.

Kigai's twisted smile deepened. 

"You don't need to understand. The age of darkness will reign for eons," 

he proclaimed ominously.

In that moment, Mamoru weakened but defiantly, stirred, and tried to stand. 

"What the hell are you talking about?" he exclaimed, only to falter and collapse again.

The elders, realizing the urgency, shared the sacred knowledge. 

"The flute can only be obtained with the chant of the dragon's tongue," 

they revealed a hint of desperation in their voices. The fate of Shinpi hung in the balance as the confrontation unfolded, with Jin ready to face the impending threat.

Jin, enraged by the elders' revelation, screamed at them, 

"What are you doing? Wasn't this place supposed to be protected by the will of the universe?"

Kigai, with an unsettling calmness, responded, 

"In ordinary circumstances, yes. But as for now, a power beyond your knowledge has intervened. Don't worry; he is not powerful enough to defy the universe, but he can intervene for a few minutes. Now, if you'll excuse me."

Kigai then began chanting the Dragon's tongue.

In the Dragon's tongue, he uttered,

 "大いなる龍よ、禁断の洞窟への扉を開く龍の笛を見せてくれ," Ōinaru ryū yo, kindan no dōkutsu e no tobira o hiraku ryū no fue o misete kure."

which translates to 

"Great dragon, show me the dragon flute that opens the door to the forbidden cave."

The air hummed with an otherworldly energy as the chant echoed through the village, setting an ominous tone for what lay ahead.

As Kigai's chant resonated through the air, a mystical flute materialized in his hands. With an eerie grace, he began to play the haunting melody of the dragon, the notes weaving through the atmosphere with an otherworldly allure. The village fell silent, captivated by the eerie tune that seemed to echo the ancient power of the dragon.

As Kigai's melody reaches its climax, a mysterious staircase materialized, leading to a floating cave at the top—the Forbidden Cave. The villagers, though fearful, couldn't help but be entranced by the haunting music that accompanied Kigai's ascent.

Makoto and Jin exchanged uneasy glances, realizing the gravity of their destiny tied to this enigmatic place.

Jin's anger intensified, his eyes ablaze with determination. Makoto, witnessing this unprecedented fury, couldn't hide his astonishment. The villagers, scared yet resolute, prepared for a battle to protect their culture and heritage.

Kigai, ascending the stairs, glanced over his shoulder with a sinister grin. 

"You may try to resist, but destiny can not be denied," 

he taunted, disappearing into the eerie glow of the Forbidden Cave.
