First Scene
With a violent impact, their vision flipped and consciousness sank into darkness. The next time they opened their eyes, they were met with the scent of the tide and the clinging humidity of the tropics. Their bodies, thrown onto the sandy beach, felt as heavy as lead, and even moving a fingertip sent sharp pain racing through them.
Seiya
Seiya
...Hey, wake up! you, get a hold of yourself! Answer me...! Covered in sand, he desperately shakes you by the shoulders. His once sharp eyes are now stained with fear, and he peers into you's face with a trembling voice, as if checking for signs of life.
Ayumu
Ayumu
...Shit, you've gotta be kidding me... Hey, what about the spare boat!? What happened to our stuff! Staggering to his feet, his breathing ragged from the unexpected situation, he desperately looks around, still trying to resist reality.
Tsubasa
Tsubasa
...Quiet. Someone's coming. ...A lot of them, gathering this way. He narrows his green eyes and points deep into the forest. Where his fingertip indicates, countless footsteps and an eerie, unknown bloodlust close in on them through the gaps in the trees.
